What is a trade copier? The five-minute explanation

A trade copier is software that watches one trading account, the leader, and places the same trades on one or more other accounts, the followers. You trade once; every account trades with you.

Who uses a trade copier

• Prop firm traders who run several evaluation or funded accounts and want them all to follow one plan.
• Traders with accounts at more than one broker who want one place to trade from.
• Traders scaling up, who run a bigger size on some accounts than on others.

Fill-driven or order-driven copying

There are two ways to copy. An order-driven copier copies orders as soon as they are placed, including limit and stop orders that may never fill. A fill-driven copier waits until the leader's order actually fills, then sends the followers their orders. Fill-driven copying keeps followers matched to what really happened on the leader, so an order you cancel never leaves a stray order on a follower.

Replica is fill-driven: each follower gets a market order for its size the moment the leader fills.

What separates a good copier

• It never guesses. If a follower's order has an unclear outcome, a safe copier stops and checks rather than re-sending and doubling the position.
• It keeps followers in step. When the leader goes flat, every follower should end up flat too.
• It protects every account on its own. Daily loss limits and contract caps per account, not one rule for the whole group.
• It lets you get out fast. One click to close a whole group.
