Trade Copier: Multi-Account Order Replication
The SabrTrader Trade Copier is a built-in window that mirrors every order and position from one master trading account to an unlimited number of copy (slave) accounts in real time. It requires no third-party copier software, no separate subscription and no bridge application: the master account, the copy accounts and the per-account symbol and size rules all live inside the platform. This page documents the full window, every setting, the arming behaviour, the two different close paths that behave differently, and the risk concepts a multi-account trader must understand before pressing Start Copying.
Overview: What the SabrTrader Trade Copier Does
A trade copier is a tool that mirrors orders and positions from one account (the master account) to one or more other accounts (the copy accounts, also called slave accounts) in real time. You trade once, manually, on the master; every linked copy account receives a replica of that order within milliseconds.
In SabrTrader the copier is a native platform feature. There is no add-on to purchase, no external bridge process to keep running, and no separate copier licence. It is opened from the platform toolbar, configured in a single window, and its configuration persists between sessions.
Who the Trade Copier is for
- Prop firm traders running several evaluation or funded accounts at once (for example multiple Apex accounts) so that one setup produces payouts across every account.
- Traders splitting size across brokers, for example holding part of a position at one futures broker and part at another for margin, redundancy or fee reasons.
- Educators and trade-room leads mirroring executions into student or observer accounts.
- Traders testing configuration, who mirror a live master into SIM accounts to compare behaviour without risking capital.
What the copier replicates
| Event on master | Behaviour on copy accounts |
|---|---|
| Market order (buy or sell) | Replicated immediately as a market order on every armed copy account, subject to that account's symbol and size rules. |
| Limit / stop order placement | Replicated as a working order on each copy account. |
| Position scale-in (adding contracts) | Replicated; the aggregate position grows on every copy account. |
| ATM strategy brackets (target and stop) | Applied per copy account against that account's resulting position; prior brackets are cancelled and re-issued when size changes. |
| Manual exit or flatten | Replicated, but the effect on the copier's armed state depends on which surface you close from — see the comparison table below. |
The core value is simple to state: one manual trade on the master produces identical execution on every linked account, with optional per-account rules that change the instrument traded or the quantity traded.
Opening the Trade Copier Window and What It Contains
The Trade Copier button is located in the SabrTrader platform toolbar alongside the other order-entry and analysis launchers. Clicking it opens the Trade Copier as a floating pop-up window that can be docked, moved and resized like any other panel in SabrTrader's modular window layout.

Anatomy of the window
| Region | Purpose |
|---|---|
| Master account selector | A single-select control naming the account whose orders are the source signal. One master per configuration. |
| Copy account list | A multi-select list of every account currently connected to the platform. Ticking an account enrols it as a copy account. |
| Per-account rule columns (right-hand panel) | Optional fields per copy account for symbol isolation, symbol translation and size multiplier. Blank means pure 1:1. |
| Inline help text | Short descriptive text inside the window explaining that blank rule fields produce 1:1 copying of every instrument. |
| Start Copying / Stop Copying control | The arm/disarm switch. Nothing is mirrored until Start is pressed. |
| Live monitor tabs (bottom of window) | One tab per copy account showing connection state, working orders, current position and fills, used to verify replication and spot latency or rejects. |
Configuration is saved with your profile, so the master, the copy account selection and every per-account rule are still in place the next time the platform starts. This means the copier can be fully preconfigured before the session opens, leaving only one action — pressing Start Copying — as part of the pre-session routine.
Feature Reference: Master, Copy Accounts and Per-Account Rules
Selecting the master account
The master account is the account you actually trade. Orders originate there and nowhere else. You can send those orders from any SabrTrader order-entry surface:
- The SuperDOM / depth-of-market ladder, by clicking bid or ask price cells.
- The Chart Trader panel docked to a chart.
- Any other order entry panel bound to the master account.
Only one account can be master in a given configuration. Every order that account sends is a source signal, including orders generated automatically by an ATM strategy such as the profit target and protective stop attached after an entry fills.
Choosing copy accounts
The copy account list shows every account the platform is currently connected to: SIM accounts, prop firm accounts on Rithmic infrastructure (Apex evaluation and funded accounts, for example), and live broker accounts. Ticking multiple entries enrols them all.

There is no hard cap on the number of copy accounts. Multi-account prop traders commonly run groups of 10, 20 or more accounts from a single master. Practical limits come from margin, connection bandwidth and the trader's ability to monitor the group, not from the copier itself.
Mixing SIM and live accounts in the same group is permitted and is the recommended way to rehearse, but it is also the most common source of confusion: a fill on a SIM tab looks identical to a fill on a funded tab. Name accounts clearly so the monitor tabs are unambiguous.
Per-account rules: isolation, translation and multipliers
The right-hand panel of the window holds the optional rules. Rules are set per copy account, so each account in the group can have a different mandate.

| Rule configuration | Meaning | Example |
|---|---|---|
| All fields blank | Pure 1:1 copy ratio: copy every instrument, at the same quantity as the master. | Master buys 2 MNQ → copy account buys 2 MNQ. |
| Symbol isolation filter | A whitelist restricting which master instruments reach this account. Anything not listed is ignored. | Master trades MES and MNQ; the account is set to MES only, so MNQ trades never appear on it. |
| Symbol translation | Converts the master instrument into a different but correlated instrument on the copy account. | Master trades ES; copy account trades MES. |
| Size multiplier / lot ratio | Scales the copied quantity for that account. | Master sells 1 ES; copy account sells 5 MES. |

The arithmetic of mini-to-micro translation
The ES (E-mini S&P 500) contract has ten times the notional value of the MES (Micro E-mini S&P 500). The same ratio holds for NQ versus MNQ. Therefore:
- Notional equivalence of 1 ES is 10 MES.
- A rule mapping 1 ES to 5 MES is a deliberate 50% risk reduction on that copy account, not an equal-size copy.
- A rule mapping 1 ES to 10 MES reproduces the master's dollar risk on the copy account.
- A rule mapping 1 ES to 1 MES gives the copy account one tenth of the master's exposure — useful for a small evaluation account.
Always compute the intended dollar risk per copy account before entering a multiplier. The copier applies the number you give it; it does not normalise notional value for you.
Start Copying and Stop Copying
The copy state is a binary armed/disarmed flag. When stopped, the window is only a configuration screen: master orders execute normally on the master and nothing is mirrored. When started, every qualifying master order is replicated.

The window shows the current state on the control itself (the button reads Start Copying when disarmed and Stop Copying when armed). Certain close actions taken from the copier window, and Flatten All, disarm the copier and require pressing Start again — this is covered in detail in the close-path section.
Live monitor tabs
The tabs at the bottom of the window are a per-account monitor. Each tab reports the account's connection status, working orders, open position and recent fills.

What to watch for on the monitor tabs:
- Quantity mismatch — one account shows a different position size than intended, usually a multiplier or mapping rule.
- Missing fill — an account shows no position after the master filled: connection, margin, or instrument permission.
- Rejected order — insufficient buying power, instrument not permitted on that account, or a prop firm rule block.
- Fill price drift — the copy fill printed at a worse price than the master fill, which is slippage caused by copy latency or thin liquidity.
- Lag — a visible delay between the master fill appearing and the copy fill appearing.
How Execution Replication Works in Practice
The following sequence reproduces the behaviour demonstrated in the walkthrough, using a master account with an ATM strategy selected and three SIM copy accounts armed.
1. First market order
Selling the market on the master with a market order — an order that executes immediately at the best available price — fills the master and, effectively simultaneously, fills every armed copy account. The monitor tabs show the position appear on each account. The ATM strategy attaches a profit target and protective stop around the new position on the master, and equivalent brackets are placed on each copy account.

2. Scaling in
Selling again on the master adds contracts. This is position scaling in. The copier replicates the additional quantity, so the aggregate position grows on every account — in the demonstration, from 2 lots to 4 lots. The previously working bracket orders for the smaller position are cancelled and re-issued against the new aggregate size, per account.

Two points matter here:
- The copier mirrors the resulting position, not just individual clicks. If the master is short 4, each 1:1 copy account should be short 4.
- ATM brackets are applied per account. Each copy account has its own target and stop orders resting at its own broker, sized to its own position. They are not a single shared bracket.
3. Exit
If the position exits because a target or stop is hit, the copier remains armed and continues to copy the next trade. If you exit manually, the behaviour depends on which surface you used — see the next section.
Critical Distinction: Closing from the Copier vs Closing from the Order Entry Surface
This is the single most important operational lesson of the Trade Copier, and the point the walkthrough repeats several times. There are two different surfaces you can close a position from, and they do not behave identically.
- Closing from the Trade Copier window (its own close/flatten control, and Flatten All) closes the position but also disarms the copier. The Start Copying button must be pressed again before the next trade is mirrored.
- Closing from the order entry surface (the DOM, SuperDOM or Chart Trader close/flatten control bound to the master) leaves the copier armed, but may close only the master position and leave the copy account position open.

Comparison table
| Action | Master result | Copy account result | Copier state after |
|---|---|---|---|
| Close / flatten from the Trade Copier window | Flat | Flat | Disarmed — press Start Copying again |
| Close / flatten from the DOM or Chart Trader | Flat | May remain open — verify on the monitor tabs | Still armed — copying continues |
| Flatten All | Flat | Flat | Disarmed — press Start Copying again |
| Profit target hit (ATM bracket) | Flat at target | Flat at that account's target | Still armed — no action needed |
| Protective stop hit (ATM bracket) | Flat at stop | Flat at that account's stop | Still armed — no action needed |
| Manual early exit | Flat | Depends on the surface used | Depends on the surface used — check both |
Early exit vs target exit
The distinction that determines whether attention is required is early exit versus target exit:
- A target exit or stop exit is handled by the bracket orders each account already holds. Every account closes itself. The copier stays in copy mode. Nothing to check beyond confirming all accounts went flat.
- An early exit — you decide to leave before the bracket triggers — is a manual action, and manual actions differ by surface. After any early exit, do two things: confirm the copier's armed state, and confirm on the monitor tabs that every copy account is actually flat.
The practical conclusion, especially with large account groups: prefer bracket exits over manual exits when copying. Bracket-managed exits are deterministic across the whole group; manual exits require a per-surface decision every time.
Orphaned positions
An orphaned position is a position left open on a copy account after the master has already gone flat. It is the direct consequence of using the close path that leaves the copier armed but does not propagate the flatten. Orphaned positions carry full market risk with no bracket relationship to your intent, and on a prop account they can breach a drawdown limit while you believe you are out of the market. Checking the monitor tabs after every manual exit is the countermeasure.
Trading Concepts Behind Multi-Account Copy Trading
Copy latency
Copy latency is the delay between the master fill and the copy account fill. It is the primary performance metric for any copier: the closer to zero, the closer the copy accounts' results are to the master's. Because SabrTrader's copier runs inside the platform rather than as an external bridge, there is no inter-process hop, so replication is effectively instantaneous from the trader's perspective. Real-world latency still depends on each copy account's network path and broker acknowledgement speed, which is exactly what the monitor tabs let you observe.
Slippage
Slippage is the price difference between the master fill and the copy fill. Two causes dominate. First, latency: even a small delay can mean the market has moved a tick. Second, thin liquidity: if the master takes the available size at a price, a simultaneous copy order for the same or larger size may have to reach deeper into the book. Slippage is therefore worse in fast markets, at the RTH open, around economic releases, and when copy accounts are sized larger than the master.
Correlated risk and over-leverage
Correlated risk is the concentration created when many accounts hold the same position in the same instrument at the same time. A copier does not diversify risk — it multiplies one decision. If the master is short 4 MES and ten copy accounts each hold 4 MES, the trader is short 44 MES in aggregate. One adverse move hits every account simultaneously. Size the master with the aggregate exposure in mind, not the single-account exposure.
Prop firm consistency and drawdown rules
Prop firm accounts carry rules: maximum daily loss, trailing or end-of-day drawdown, maximum contract size, permitted instruments, news-trading restrictions and consistency requirements that cap how much of total profit may come from a single day or trade. Because copied trades are identical, a rule-breaking trade breaks the rule on every account at once. Two consequences follow:
- Set the master's size to the smallest per-account contract limit in the group, or use per-account multipliers to keep each account inside its own limit.
- Use the symbol isolation filter for accounts with instrument restrictions, so a trade in a disallowed product never reaches them.
Micro versus mini contracts
ES and NQ (minis) are ten times the notional value of MES and MNQ (micros). Micros exist precisely so that small accounts can express the same idea with one tenth of the dollar risk per tick. Symbol translation plus a size multiplier is how the copier bridges the two: a master trading minis for its own liquidity and tick precision can feed micro-sized copy accounts at whatever fraction of risk each account can carry.
SIM accounts
A SIM account is a simulated trading account with virtual funds. In copier work its purpose is configuration testing: you can verify the master selection, the rule fields, the arming behaviour and both close paths with zero financial risk. Every operational surprise in this document can be reproduced on SIM in under five minutes.
DOM order entry as a copy signal
DOM order entry means placing orders directly on the depth-of-market price ladder. The copier does not care which surface produced the master order — DOM clicks, chart trader buttons and ATM-generated brackets are all treated as master signals. This is why the copier composes cleanly with SabrTrader's order-flow tools: you read the tape on the SuperDOM and liquidity heatmap or a footprint chart, click once, and the whole account group is positioned.
Tutorial: Configuring and Verifying the Trade Copier Step by Step
Do this entire sequence with SIM accounts the first time. It takes a few minutes and eliminates almost every failure mode described later on this page.
- Connect all accounts. In the Control Center Connections tab, connect every account you intend to use — the master and all copy accounts. Prop firm and futures accounts typically connect through Rithmic; equity and options accounts through their own broker connection such as Schwab or Interactive Brokers. Only connected accounts appear in the copier list.
- Open the Trade Copier. Click Trade Copier in the platform toolbar. The window opens with any previously saved configuration intact.
- Select the master account. Choose the account you will actually click orders on. Confirm your DOM and Chart Trader are bound to this same account.
- Tick the copy accounts. Select every account that should receive replicas. Start with two or three SIM accounts for the test run.
- Set the per-account rules. Leave all fields blank for pure 1:1 copying. Otherwise enter a symbol isolation whitelist (for example MES only), a symbol translation (ES → MES) and/or a size multiplier (1 → 5) for each account that needs it. Read the inline help text in the window to confirm the field semantics.
- Select an ATM strategy on the master. Choose the ATM template that will attach your profit target and protective stop on fill. Brackets are the preferred exit mechanism when copying.
- Press Start Copying. Confirm the control now reads Stop Copying, indicating the copier is armed.
- Fire a 1-lot test order. Send a single-contract market order from the DOM on the master. Check every monitor tab: each copy account should show a fill of the expected quantity in the expected instrument, plus its own target and stop.
- Test a scale-in. Send a second order in the same direction. Confirm each account's position grew and that the old brackets were cancelled and replaced with brackets sized to the new aggregate position.
- Test each close path deliberately. Close once from the DOM/Chart Trader and note that the copier stays armed — then verify on the tabs whether any copy account is still in position. Re-enter, close once from the Trade Copier window, and note that the copier disarms. Re-arm and let a third trade exit on its ATM target to confirm the copier stays in copy mode.
- Press Flatten All and verify. Confirm every account reads flat with no working orders, and remember that Flatten All also disarms the copier.
- Only then swap in live or funded accounts. Re-check margin and buying power on each, re-check per-account rules against each account's contract limit, press Start Copying, and keep the monitor tabs visible for the session.
Best Practices for Multi-Account Copy Trading
- Rehearse on SIM before every configuration change. Any change to the master, the account list or a multiplier deserves one test order on SIM before real size touches it.
- Keep master size small and scale on the copy side. Trade 1 lot on the master and use per-account size multipliers to reach target size on each copy account. This keeps the master's own risk trivial and makes per-account sizing explicit rather than implicit.
- Prefer ATM targets and stops over manual exits. Bracket exits close every account deterministically and leave the copier armed. Manual exits introduce the close-path distinction on every trade.
- Arm the copier as a fixed pre-session checklist item. The single most common failure is trading with the copier stopped. Make pressing Start Copying the last step before the first trade, and re-check it after any flatten.
- Keep the monitor tabs visible. Dock the Trade Copier where you can see the tabs without switching windows. Verification is only useful if it is continuous.
- Verify flat on every account at session end. Do not rely on the master being flat. Read every tab.
- Name accounts clearly and consistently. Include the broker or firm and whether the account is SIM, evaluation, funded or live. Ambiguous names cause the wrong master to be selected.
- Check margin and buying power on every copy account before the session. A partially filled group is worse than no fill: the master and part of the group are positioned and part is not.
- Use symbol isolation to protect restricted accounts. If an account may only trade one product, whitelist it rather than remembering to avoid the other product manually.
- Size to the aggregate, not the account. Compute total exposure across all accounts before deciding the master's lot size.
- Set the master's size to the tightest limit in the group. Then raise individual accounts with multipliers where their rules allow it.
- Practise the whole workflow in Market Replay or SIM so that the arming and close-path habits are automatic before real money is involved.
Common Mistakes and Edge Cases
| Mistake | What goes wrong | How to avoid it |
|---|---|---|
| Forgetting to press Start Copying | The master trades alone. Copy accounts stay flat and the trade cannot be reproduced retroactively at the same price. | Make arming a checklist item; confirm the button reads Stop Copying before the first order. |
| Assuming any close flattens everything | Closing from the order entry surface can leave copy accounts in position while the master is flat — an orphaned position with live risk. | Learn the close-path table; verify every tab after any manual exit. |
| Not noticing the copier disarmed | After a copier-window close or Flatten All, the next trade is master-only. | Re-arm immediately after every flatten; glance at the control before each new entry. |
| Selecting a live account as master during a test | A test order becomes a real position at real risk. | Use unmistakable account names; keep a SIM-only test configuration. |
| Mixing SIM and live in one group without noticing | The trader reads a SIM fill as confirmation that a funded account filled. | Label accounts by environment; check the specific funded tabs, not just the first tab. |
| Setting a multiplier without accounting for notional difference | 1 ES mapped to 1 MES gives one tenth the exposure; mapped to 10 MES gives full exposure. A misjudged multiplier silently misprices risk. | Compute dollar risk per tick per account before entering the multiplier. Remember 1 ES = 10 MES notional. |
| Insufficient margin on one copy account | Part of the group fills and part rejects, producing an unintended, uneven aggregate position. | Check buying power on every account pre-session; watch the monitor tabs for rejects. |
| Ignoring rule differences between prop accounts | A trade that is inside limits on one funded account breaches contract size, instrument or drawdown rules on another. | Use per-account multipliers and symbol isolation to enforce each account's own limits. |
| Scaling in without re-checking brackets | The trader assumes old brackets still protect the position when they have been cancelled and replaced. | Confirm the new bracket quantities on each tab after every scale-in. |
| Over-leveraging through correlated risk | Twenty accounts holding the same position means one adverse move hits everything at once; a normal-looking per-account size becomes an oversized aggregate bet. | Size to aggregate exposure; reduce master size as account count grows. |
| Leaving the copier armed after the session | An accidental click on the master propagates to every live account. | Press Stop Copying and confirm all accounts flat at session end. |
| Trading a fast release with large copy size | Latency plus thin liquidity produces meaningful slippage across every account simultaneously. | Reduce size around scheduled events or stand aside; use limit entries where the strategy allows. |
Frequently Asked Questions
Do I need to buy separate trade copier software to copy trades in SabrTrader?
No. The Trade Copier is built into SabrTrader. It is opened from the platform toolbar as a native window, requires no third-party copier application, no bridge process and no additional subscription. Because it runs inside the platform there is no extra inter-process hop, which is why replication is effectively instantaneous.
How many copy accounts can I run at once?
There is no hard limit imposed by the copier. Traders commonly run 20 or more copy accounts from one master. The practical constraints are margin and buying power on each account, the quality of each account's connection, and your own ability to monitor the group on the live monitor tabs.
Why are my trades not copying even though the accounts are selected?
The most likely cause is that the copier is not armed. Nothing is mirrored until Start Copying is pressed; the control should read Stop Copying while armed. The second most likely cause is a symbol isolation filter that excludes the instrument you traded — for example an account whitelisted to MES will ignore an MNQ trade. Third, the copier may have been disarmed automatically by a close action taken from the copier window or by Flatten All.
How do I copy an ES trade as MES contracts on my other accounts?
Use symbol translation with a size multiplier in the per-account rule panel: map the master instrument ES to MES on that copy account and set the quantity factor. Because 1 ES equals 10 MES in notional value, mapping 1 ES to 10 MES reproduces the master's risk, 5 MES halves it and 1 MES gives one tenth of it. Choose the number based on the dollar risk each account can carry.
Can I copy only one instrument and ignore the rest of my master account's trades?
Yes. That is the purpose of the symbol isolation filter. Whitelist the instrument you want on that copy account — for example MES only — and any other instrument traded on the master, such as MNQ, is not copied to that account. Filters are per account, so one account can be isolated while others copy everything.
Does the copier stay armed when a profit target or stop is hit?
Yes. When a position closes because an ATM bracket target or protective stop is hit, the copier remains in copy mode and continues to mirror the next trade. No re-arming is needed. Only manual close actions require attention, and only some of them disarm the copier.
Why did the copier stop after I flattened my position?
Because you flattened from the Trade Copier window, or used Flatten All. Both close the positions and disarm the copier, so Start Copying must be pressed again before the next trade will be mirrored. Closing from the DOM or Chart Trader instead leaves the copier armed — but may leave copy account positions open, so verify the monitor tabs.
Can I mix SIM accounts and live or prop firm accounts in the same copy group?
Yes, and mirroring a live master into SIM accounts is a legitimate way to observe behaviour. Be careful: a fill on a SIM tab looks identical to a fill on a funded tab, so it is easy to read a simulated confirmation as proof that a funded account filled. Name accounts explicitly by environment and check the specific tabs that matter.
How fast are copied fills, and how do I check for lag?
Replication is effectively instantaneous — in the demonstration, copy accounts fill at the same moment as the master. Copy latency is the metric to watch, and the live monitor tabs at the bottom of the Trade Copier window are the tool for watching it. Compare the timestamp and fill price on each copy account tab against the master. Persistent lag or price drift usually indicates a connection problem on that specific account rather than a copier problem.
What happens if one copy account does not have enough margin?
That account's order is rejected while the rest of the group fills. The result is an uneven aggregate position: the master and most accounts are positioned, one is not. The rejection appears on that account's monitor tab. Check buying power on every copy account before the session, and scan the tabs after the first fill of the day.
Are ATM stops and targets copied to every account?
Yes. When an ATM strategy is active on the master, each copy account receives its own bracket orders — a profit target and a protective stop — sized to its own resulting position. They are separate orders resting at each account's broker, not a shared bracket. When you scale in, the old brackets are cancelled and new ones are issued against the new aggregate size on each account.
Can each copy account use a different position size?
Yes. The size multiplier is a per-account setting, so one account can copy 1:1, another can copy at five times, and another can trade a translated micro instrument. This is how a single master trade can respect different contract limits on different prop firm accounts.
Does copying work with prop firm consistency and drawdown rules?
The copier will send whatever you configure; it does not enforce firm rules. Because copied trades are identical, a rule-breaking trade breaks the rule on every account simultaneously — a daily-loss or trailing-drawdown breach can hit the whole group at once. Manage this by sizing the master to the tightest limit in the group, using per-account multipliers to stay inside each account's contract cap, and using symbol isolation for accounts with instrument restrictions.
How do I test the trade copier safely before going live?
Build the configuration with SIM accounts only, arm the copier, send a 1-lot market order and verify every monitor tab shows the expected fill. Then test a scale-in, then test each close path in turn — DOM close, copier-window close, Flatten All and a bracket target exit — noting the copier's armed state after each. Finally confirm every account is flat. Only then substitute live or funded accounts.
What is the difference between the master account and a copy account?
The master account is the account you trade manually; its orders are the only source signal for the copier. A copy account (slave account) receives an automatic replica of those orders and is not traded directly. There is exactly one master per configuration and any number of copy accounts.
Which order entry surfaces can generate copied orders?
Any surface bound to the master account: the SuperDOM or DOM ladder, the Chart Trader panel on a chart, and orders generated automatically by an ATM strategy. The copier treats them all identically as master signals.
Does the Trade Copier configuration survive a platform restart?
Yes. The master selection, copy account list and all per-account symbol and size rules are saved with your profile, so the copier can be preconfigured before the session. The armed state, however, is an operational flag — always confirm Start Copying is pressed at the start of a session.
Will copied fills always be at the same price as the master fill?
Not necessarily. Any price difference is slippage, caused by copy latency or by thin resting liquidity when several accounts take the same price simultaneously. Slippage is larger in fast markets and when copy accounts are sized larger than the master. Compare fill prices across the monitor tabs to measure it on your own setup.
What does leaving all the per-account rule fields blank do?
Blank fields produce a pure 1:1 copy ratio: the copy account trades the same instrument at the same quantity as the master, for every instrument the master trades. The window's inline help text states this behaviour. Rules only need to be entered when you want isolation, translation or a different size.
Is the Trade Copier useful for a single-account trader?
It has limited value with only one account, since there is nothing to mirror to. Single-account traders sometimes mirror a live master into a SIM account to keep a parallel record or to test how a larger size would have behaved. The feature's main audience is traders running multiple funded, evaluation or broker accounts.
Troubleshooting
Nothing copies at all — the master fills but every copy account stays flat
Check in this order:
- The copier is stopped. Press Start Copying; the control should then read Stop Copying.
- A previous close from the copier window or a Flatten All disarmed the copier without you noticing.
- A symbol isolation filter excludes the instrument you traded on every account.
- The wrong account is selected as master — you are trading an account that is not the signal source.
One specific account is not filling while the rest of the group fills
Isolate the cause on that account's monitor tab:
- Connection down — reconnect the account in the Control Center Connections tab.
- Insufficient margin or buying power — fund the account or reduce its size multiplier.
- Instrument not permitted on that account, or excluded by its own symbol isolation filter.
- Account rule breach — a prop firm daily-loss, drawdown or contract-size block is rejecting orders.
A copy account filled the wrong quantity
This is a rule configuration issue, not a copier fault. Open the per-account rule panel and check the size multiplier and the symbol translation for that account. Remember that translating minis to micros changes notional value by a factor of ten: 1 ES to 5 MES is half the master's exposure, not an equal copy. Correct the field, then re-test with a 1-lot order.
A copy account is still in position after I closed the master
You used the close path that leaves the copier armed but does not flatten the group — a close from the DOM or Chart Trader. Flatten the orphaned position directly on that account, or use Flatten All from the copier and remember that this also disarms copying. To prevent recurrence, exit via ATM bracket targets and stops rather than manual clicks, and check every monitor tab after any early exit.
The copier disarmed itself unexpectedly
It did not disarm spontaneously. A close or flatten action taken from the Trade Copier window, or pressing Flatten All, disarms the copier by design. Press Start Copying again. Build the habit of re-arming immediately after every flatten and glancing at the control before each new entry.
Copied fills are arriving late or at noticeably worse prices
Compare timestamps and fill prices per account on the monitor tabs to identify whether the delay affects all accounts or one. All accounts late points to local network or CPU contention — close unnecessary windows and check the internet connection. One account late points to that account's broker route or connection. Persistent price drift with normal timing is slippage from thin liquidity: reduce size, avoid the fastest moments of the session, or use limit entries.
A copy account does not appear in the copy account list
Only accounts currently connected to the platform are listed. Open the Control Center Connections tab and connect the account, then reopen or refresh the Trade Copier. For futures prop accounts, confirm the correct Rithmic system and gateway are selected; for broker accounts, confirm the connection is authorised and account linking selected that account.
Brackets disappeared after I added contracts
This is expected. When the position size changes, the working target and stop orders for the old size are cancelled and replaced by brackets sized to the new aggregate position, on the master and on each copy account. Verify the new bracket quantities on each monitor tab after every scale-in rather than assuming the original protection is still in place.
I flattened everything but one account still shows working orders
Flattening closes positions and should cancel working orders, but a rejected or in-flight cancel can leave a resting order. Cancel the remaining orders directly on that account, then confirm the tab shows no position and no working orders. Never end a session without reading every tab.
A test order intended for SIM hit a funded account
The master or the copy account selection included a live account. Stop copying immediately and flatten. Then rename accounts so environment is unambiguous, and keep a separate saved configuration containing only SIM accounts for testing.
Glossary
- 1:1 copy ratio
- Default copier behaviour in which each copy account trades the same instrument and the same quantity as the master. It is produced by leaving all per-account rule fields blank.
- ATM strategy
- An automated trade management template that automatically attaches a stop-loss and profit target when an entry order fills. With the copier armed, equivalent brackets are applied per copy account.
- Bracket order (target and stop)
- A paired profit target and protective stop placed around an open position. When position size changes, existing brackets are cancelled and re-issued against the new aggregate size.
- Chart Trader
- The order-entry panel docked to a SabrTrader chart for placing, modifying and managing orders directly on the chart. Orders sent from Chart Trader on the master are copied.
- Copy account (slave account)
- A linked account that automatically receives a replica of the master account's orders. Copy accounts are not traded directly; they are enrolled by ticking them in the Trade Copier window.
- Copy latency
- The delay between the master fill and the copy account fill. It is the key performance metric for any copier and is observed on the live monitor tabs.
- Copy state (started/stopped)
- The armed/disarmed flag of the copier. No orders are mirrored until Start Copying is pressed; pressing Stop Copying, closing from the copier window, or Flatten All returns it to stopped.
- Correlated risk / over-leverage
- The risk concentration created when many accounts hold the same position in the same instrument at the same time. A copier multiplies a single decision rather than diversifying it, so aggregate exposure grows with account count.
- DOM order entry
- Placing orders directly from the depth-of-market price ladder by clicking bid or ask price cells. The copier treats DOM orders on the master as source signals like any other.
- Early exit vs target exit
- The distinction that determines whether the copier needs attention after a position closes. A target or stop exit leaves the copier armed and closes every account via its own brackets; a manual early exit behaves differently depending on which surface it was performed from.
- Flatten
- Closing all open positions and cancelling working orders for an account. In SabrTrader, flattening from the Trade Copier window (and Flatten All) also disarms the copier.
- Flatten All
- A control that closes all positions and cancels working orders across the accounts in scope. Pressing it disarms the copier, so Start Copying must be pressed again.
- Market order
- An order that executes immediately at the best available price. Used in the demonstration because it makes replication speed directly visible.
- Master account
- The account you trade manually. Every order it sends — from the DOM, Chart Trader or an ATM strategy — is the source signal for the copier. Only one master exists per copier configuration.
- MES
- The Micro E-mini S&P 500 futures contract, one tenth the size of ES; a liquid, low-notional instrument commonly used as the copy-side instrument when translating from ES.
- Micro vs mini contracts
- E-mini contracts such as ES and NQ carry ten times the notional value of their micro counterparts MES and MNQ. The ratio must be accounted for whenever a copier translates a mini master trade into micro contracts.
- MNQ (Micro E-mini Nasdaq-100)
- The micro-sized CME futures contract on the Nasdaq-100 index, one tenth the size of the E-mini NQ. Frequently the instrument excluded or whitelisted by a symbol isolation filter.
- Orphaned position
- A position left open on a copy account after the master has gone flat, typically because the close was taken from an order entry surface that did not propagate the flatten. It carries full market risk and can breach a prop account drawdown limit unnoticed.
- Position scaling in
- Adding contracts to an existing position. The copier replicates the additional quantity on every armed copy account and re-brackets the new aggregate position.
- Prop firm account
- An evaluation or funded trading account issued by a proprietary trading firm. For futures these typically run on Rithmic infrastructure and appear in the copier account list once connected.
- Prop firm consistency and drawdown rules
- Account rules imposed by a proprietary trading firm — maximum daily loss, trailing or end-of-day drawdown, contract size caps, permitted instruments and consistency requirements. Because copied trades are identical, a breach affects every account simultaneously.
- Prop firm multi-account trading
- Trading several funded or evaluation accounts simultaneously so that one trade setup produces payouts across multiple accounts. It is the primary use case for the trade copier.
- SIM account
- A simulated trading account with virtual funds, used to test copier configuration, arming behaviour and close paths without financial risk.
- Size multiplier / lot ratio
- A per-account factor that scales copied quantity. It is applied independently per copy account, so different accounts can carry different sizes from the same master trade.
- Slippage
- The price difference between the master fill and the copy fill, caused by copy latency or by thin resting liquidity when multiple accounts take the same price at once.
- SuperDOM
- A depth-of-market ladder that displays resting bid and ask liquidity at each price level and allows orders to be placed, modified and cancelled directly from price.
- Symbol isolation filter
- A whitelist that restricts which master instruments are copied to a given account. Instruments not on the list are ignored for that account.
- Symbol mapping / translation
- A rule that converts the master instrument into a different but correlated instrument on a copy account, typically mini to micro.
- Trade copier
- A tool that mirrors orders and positions from one master account to one or more copy accounts in real time. In SabrTrader the copier is built into the platform and requires no third-party software.
