Copy trading turns a follower's exchange account into a live mirror of a chosen trader's activity, scaling every entry and exit to the amount of capital the follower has allocated rather than requiring the follower to place orders themselves.
On most centralized exchanges, followers browse a public leaderboard of "lead" or "master" traders, filtering by track record, win rate, and risk level, then allocate a fixed amount to copy one or several of them. When a lead trader opens a spot or futures position, the platform's matching engine mirrors it across every follower's account in proportion to their allocation, and closes it the same way. Because each follower's trade fills as a separate order, small differences in price and timing mean the actual return rarely matches the lead trader's headline result, and the gap tends to widen as more people copy the same trader at once.
Lead traders are usually paid through profit sharing, commonly 10 to 15 percent of a follower's realized gains, with nothing owed if the follower ends up at a loss; ordinary trading and funding fees still apply on top. Many leads run automated trading bots rather than trading manually, and unlike backtesting against historical data, copy trading followers are exposed to live, forward-looking outcomes with no guarantee the pattern repeats.
Key risks include slippage in volatile markets, a lead trader abruptly raising leverage or changing strategy, and leaderboards that reflect survivorship bias rather than durable skill. Copy trading does not remove market risk: followers can still lose money even when copying a historically profitable trader.
