The idea is simple: you trade one master account, and a copier replicates every fill onto your follower accounts in near real time. Ten funded accounts, one decision. The hard part isn't the copying — it's keeping each follower individually controllable and staying inside every firm's rules.
01Why per-follower control is non-negotiable
A copier that can only mirror is a liability. The moment one follower needs a different stop, an early exit, or a manual flatten — and you can't do it without affecting the master or the other followers — you've lost control of your risk. This is the single most important capability to test before trusting any tool with real accounts.
- Per-follower stop adjustment — move a stop on one account without touching the rest.
- Independent manual close — flatten one follower while the master stays open.
- Per-account sizing — different contract counts to respect each firm's limits.
- Hard lockouts — auto-flatten a follower at its own drawdown threshold.
02Connection level beats platform
Modern copiers operate at the broker-API level (Rithmic, Tradovate), not the charting platform. That means your master can run on whatever you like — your charts and order-flow tools are untouched — and the copier replicates underneath. The practical consequence: the follower firm's charting app no longer matters. What matters is whether the account is reachable over a supported connection.
In 2026 that's effectively Rithmic and Tradovate, which between them cover almost every futures prop firm. (ProjectX went exclusive to a single firm in early 2026, so it's no longer a useful cross-firm bridge.)
03Latency and why it matters for scalps
On a 2–8 tick target, replication delay is the difference between an identical fill and a worse one. Desktop, local copiers running near the exchange typically replicate in single-digit milliseconds; cloud copiers add network hops and can run 100ms+. For scalping, faster and local generally wins; for swing trading, latency barely matters.
04Three rules that protect you
- No counter-positions. Some firms instantly liquidate if you hold opposite positions across any accounts you control — including correlated instruments like ES vs MES. Your copier must never create opposing positions through a malfunction.
- Firm approval. Copying your own accounts is allowed at most firms; copying other people's trades usually isn't. Confirm the firm permits your specific tool.
- Sim first. Validate per-follower stop, manual close, and sizing in simulation before a single live contract.
