Your inputs
Stress-test your account against the trader's worst historical period.
Worst-case scenario
If history repeats — or gets worse — here's what your account looks like.
Why drawdown matters more than ROI
The asymmetry of losses
A 50% drawdown requires a 100% gain to recover. A 75% drawdown requires a 300% gain. That's why drawdown is the single most important number on a lead trader's profile — bigger than ROI, bigger than win rate. The recovery percentage in the results panel shows you exactly what you'd need to climb back to break-even.
What's a healthy max drawdown?
Under 5% over 30 days is excellent. 5–15% is normal for active traders. Anything above 25% is a yellow flag, and above 40% is a red flag — that's casino territory regardless of what the ROI looks like. The screenshot examples in our guide show traders at 0.44%, 0.55%, and 5.83% which range from very tight to active.
Why use a stress multiplier?
Because the next drawdown can always be worse than history. A trader showing 5% max DD over 30 days could easily see 10–15% during a flash crash, exchange outage, or correlated crypto sell-off. Sizing for 1.5× or 2× the displayed max gives you a survival buffer. If 2× the displayed DD would force you out of the trade, your position is too big.
Where do I set a stop-loss in copy trading?
On Bitunix, the stop-loss field is on the copy setup page (we recommend 5–25% depending on the trader's history). On BTCC and MEXC the placement is similar. Setting a stop-loss doesn't override the lead trader's positions — it triggers a market exit on your follower account once your equity drops by that percent.
