Copy trading
Automatically mirroring another account's trades in your own account, usually through a signal or copy service.
Copy trading reproduces another trader’s or system’s positions, scaled to the subscriber’s own deposit and leverage, without the subscriber choosing each trade themselves.
A copied result is never identical to the source account’s published one: spread, slippage, latency and the subscriber’s own broker all change the fill price, and the effect is largest on short trades and on trades opened during a widened-spread hour.
