Trade Copier

A trade copier is software that monitors a source (leader) trading account and automatically replicates every trade to one or more destination (follower) accounts. In the futures trading world, trade copiers are essential tools for traders managing multiple prop firm funded accounts.

How a trade copier works:

1. The software subscribes to the leader account's execution-report stream at the broker.
2. When a leader fill arrives, the copier dispatches matching orders to all follower accounts in parallel.
3. The system handles entries, exits, stop losses, profit targets, and position sizing.

What to look for in a futures trade copier:

• Fill-triggered, not alert-triggered: The copy should fire on the leader's actual broker fill, not on a chart alert or webhook, so followers react to what really executed.
• Bracket order support: When you place an entry with a stop loss and profit target, all three legs should be copied — not just the entry.
• Rogue trade detection: If a trade is placed directly on a follower account (not through the copier), the system should detect and handle it to prevent untracked exposure.
• Per-account controls: Enable/disable individual followers, set contract ratios, and restrict which symbols are copied.
• Reliability: The copier runs 24/7 during market hours. Connection drops should reconnect automatically without missing trades.

TradeDupe is a trade copier built specifically for Tradovate-based futures prop firms: a hosted worker listens to Tradovate's execution-report stream and dispatches follower orders in parallel the moment the leader fill arrives, with bracket order copying and automatic rogue-fill close.
