How the Trade Copier works
Mirror one account onto many, each sized the way you want, all in the cloud.
The Trade Copier mirrors one account, the leader, onto other accounts, the followers. When the leader opens, adds to, or closes a position, Lune places the matching order on every follower. Each follower can trade a different size, so one master account can drive many accounts at once.
Everything runs in the cloud. Your computer and your broker platform can be closed, and the copier still mirrors trades.
What a copy group is#
A copy group is one leader plus its followers. You build it once, then turn it on.
Choose one account as the master. Its fills drive the group.
Select the accounts that mirror the leader. You can add up to 200 followers per group.
Set a per-account size so a small account and a large account each trade the right amount. See Size each follower.
Lune fans out to all followers in parallel, so every account fills close together with low latency.
Copy activity is its own lane#
The Trade Copier page shows only trades the copier created. Manual trades live in the Cockpit. Automated trades live in Auto Trader. Keeping the three lanes separate means you always know which system opened a position.
The leader can be driven by anything: your manual trades, an automation, or trades you place by hand at the broker. The copier mirrors the leader's fills no matter where they come from.
Built to protect followers#
The copier caps every exit to what a follower actually holds, blocks accidental opposite positions, and pauses a follower when its state drifts from the broker. Read Copy safety to see how each guard works.
