Copying trades across multiple prop firm accounts

Why traders run more than one account

Evaluations are cheap compared to the payout they unlock, so serious prop traders diversify: several evaluations at once, accounts at more than one firm, a mix of sizes. The strategy is one strategy — the problem is execution. Every extra account multiplies the clicks, the chances to fat-finger a quantity, and the odds that one account misses the exit while the others take it.

The three ways traders copy trades

Manually. Free, and fine at two accounts. Beyond that it breaks down precisely when it matters: fast markets, partial exits, bracket adjustments. A stop you forget to move on account four is a real loss, not a rounding error.

Cloud copying services. A server sits between your broker accounts and copies over the internet. Strengths: nothing to install, works across platforms, your computer can be off. Trade-offs: your orders take an extra network hop (for scalpers, real milliseconds on every order), your broker credentials live on someone else's server, and it's a subscription forever.

Local copiers. Software on your own machine, inside your trading platform, mirroring trades between the accounts connected there. Strengths: the shortest possible path between accounts, your credentials never leave your computer, and — with the right tool — per-account risk controls a server can't apply as fast. Trade-offs: your machine or VPS has to be on, and setup quality varies wildly between tools.

The risks nobody puts on the sales page

• Copying multiplies mistakes as faithfully as it multiplies good trades. One bad market read at full size on eight accounts is eight times the damage. Per-account quantity caps and a per-account daily loss limit are not luxury features; they are the difference between a bad day and a blown fleet.
• Firm rules differ, and they are your problem. Some firms allow copying between your own accounts, some restrict it, some ban third-party tools entirely. Check your firm's current rules before you copy anything — and re-check, because they change.
• Consistency rules interact with copying. If your master has one huge day, every follower now has one huge day — and on a consistency-rule evaluation, that day can block passing until it's diluted. Our free consistency calculator shows the math.
• Drawdown is per account. Trailing drawdown follows each account's own balance. A follower sized too aggressively relative to its drawdown room can breach on a trade the master survives comfortably.
• Sync failures are silent killers. A copier that loses track after a platform restart or a dropped connection leaves orphan positions and unadjusted brackets. Look for tools that persist their mappings and reconcile on startup — and log everything, so you can audit what actually happened.

A safer setup checklist

1. Confirm your firm's copying rules in writing (their help center or support).
2. Pick ONE master account — the one you actually trade — and start with ONE follower.
3. Size followers by their own drawdown room, not by the master's size. Use multipliers and symbol mapping (trade NQ on the master, copy as MNQ on a small eval) deliberately.
4. Set a hard quantity cap per follower, and a daily loss limit per follower if your copier supports it.
5. Test in this order: dry-run (copies logged, nothing sent), then a paper or sacrificial account with live fills, then the smallest real size. No exceptions for "it looked fine in dry-run."
6. Run it on your own accounts for a few weeks before trusting it with size. Read the logs.

That's exactly the process we built TradeCopier around: it runs locally inside Quantower, starts in dry-run by default, persists its mappings across restarts, logs every copy with its latency, and carries a per-follower daily loss limit that stops copying to one account before a bad day blows it. The setup guide walks the test sequence, and the free config builder writes your followers.json without hand-editing JSON.
