Why a prop firm copier is judged differently from a retail copier
Prop firm accounts fail on rules, not on missed profit. Daily loss limits, drawdown models, consistency thresholds and instrument restrictions are set per account, and a copier multiplies whatever the leader does across every one of them. Three things matter more than anything else: the bracket has to arrive with the entry so no follower sits without a stop; you need to be able to switch one follower off when it is close to its daily loss limit or a payout buffer; and if a follower ends up in a position the leader does not hold — a manual click, a stale bracket leg — it has to be closed before it becomes a hedge against your other accounts.
Speed is the fourth criterion and the hardest to verify from a sales page. TradeSyncer's help center advertises an average copy speed of 20–40 ms; TradeCopia publishes no figure; TradeDupe publishes no figure either — its worker listens to Tradovate's execution-report stream and dispatches follower orders in parallel the moment the leader fill arrives, and the live feed shows each follower's result so you can judge it on your own accounts during the trial.
- Brackets mirrored with the entry, including stop moves and cancels.
- Per-follower off switch that works mid-session.
- A defined response to a follower fill the copier did not place.
- Trial on a live session before you fund a stack.
