Go to Copy Trading, select a lead trader, tap Copy, and enter your amount and you can start copy trading with the trader's parameters.

The profit difference may result from factors like manual position closure by copiers, different contract costs, changes in the lead trader's margin, leverage mismatches, copy multiplier settings, slippage, or copying failure due to shared risk limits.

When selecting lead traders, prioritize recommended ones, choose those with strong risk control strategies, and match your copy amount to their position size.
