Before you copy anyone, check:
• Win rate next to average loss. 100% usually means losers are being held.
• Drawdown including open positions
• Liquidations
• Their own trades vs copied ones
• Copy mode: fixed ratio copies their sizing and their leverage. Fixed margin makes every order the same size, which punishes traders who scale in with lots of small orders.
I'm watching all six. I'm not copying any of them... yet.
