Trade Copier
Software that replicates orders from one trading account to others in real time — the engine behind multi-account scaling, and a tool worth configuring carefully.
A trade copier is the software layer that makes copy trading possible. It watches a master account, and the instant an order fills there it sends matching orders to your follower accounts — entries, exits, stop moves, partial fills, the lot. Good copiers connect through the same platform and data infrastructure your accounts already use, so the latency between master and copy is measured in milliseconds.
The core settings you’ll configure:
- Sizing mode. Fixed ratio (1 master contract = 2 follower contracts), proportional to account size, or a fixed multiplier per account.
- Which accounts follow. Usually a checklist, so you can pause an account near its drawdown floor without unhooking everything.
- What gets copied. Some copiers mirror stops and targets; others only mirror the entry and leave management to each account.
- Risk guards. Per-account max contracts, daily loss cutoffs, or an automatic disconnect when an account crosses a threshold you set.
Set those last two properly and a copier becomes a genuine risk tool, not just a duplication tool.
A worked example of why sizing mode matters: you run a master account plus three funded accounts of different sizes. A trade goes 12 ticks against you in MNQ ($0.50 per tick). At a flat 3 contracts on every account, that’s $18 lost on each — trivial for the biggest account, but a real dent in the smallest one’s cushion. Proportional sizing solves it: each account risks the same percentage of its own buffer, so no single account gets pushed toward its floor by a routine losing trade.
One non-negotiable: confirm your firm permits copying, and on what terms, before you connect anything. Rules differ, and a copier configured against the rules can undo a lot of good work.
