Six tools for smarter copy trading decisions
Each calculator solves a different question. Use them together to vet any lead trader on Bitunix, BTCC, or MEXC before committing capital.
Profit Calculator
Plug in a trader's ROI, your capital, and profit-sharing fee. Get net take-home over 7, 30, 90, 180, or 365 days.
Open calculator →Proportional vs Fixed Amount
Compare the two copy modes side-by-side. See which mode produces better outcomes for your account size.
Open calculator →Drawdown Survival
Stress-test your account. See how many losing trades you can take and what recovery you'd need to break even.
Open calculator →Win Rate & Expected Value
Run the EV math on any lead trader. Spot real edge versus negative-EV traders disguised by high win rates.
Open calculator →Compounding Returns
Project monthly ROI over 3, 6, 12, 24 months. Toggle reinvest vs withdraw with a built-in realism factor.
Open calculator →Multi-Trader Portfolio Allocator
Split capital across 2–3 lead traders by risk-adjusted return. Reduces blended drawdown 20–40%.
Open calculator →A simple 4-step workflow
Find candidate traders
On Bitunix, BTCC, or MEXC, browse Lead Traders. Sort by 30D ROI but immediately filter out anyone with max DD over 25%.
Run the EV math
Use the Win Rate calculator to confirm their win rate plus avg win/loss sizes produce positive EV.
Stress-test drawdown
Use the Drawdown calculator with a 1.5–2× stress multiplier. If you can't survive that, size down.
Diversify & project
Use the Portfolio Allocator to split capital, then the Compounding calculator for the long view.
Common questions
Are these calculators specific to Bitunix, BTCC, or MEXC?
No — they work for any copy trading platform that exposes ROI, max drawdown, win rate, and profit-sharing ratio. That includes Bitunix, BTCC, MEXC, Bybit, Binance, OKX, KuCoin, and most other major exchanges. The calculators are platform-agnostic.
How accurate are the projections?
They're estimates, not predictions. The math is correct — but real-world results depend on whether the lead trader sustains their recent performance. Use shorter projection windows (30–90 days) for more reliable numbers. Anything beyond 90 days is a thought experiment, not a forecast.
What's the most important calculator?
The Drawdown Survival Calculator. Most copy trading losses come from underestimating worst-case scenarios — not from picking the wrong trader. If you can size your position so that 2× the trader's historical drawdown still leaves you within your stop-loss, you're playing the long game correctly.
Do these account for trading fees?
The Profit Calculator includes a trading fees field. The others abstract fees into the trader's reported ROI (which on most platforms is already net of trading fees, but not net of profit-sharing). The calculators consistently apply profit-sharing as a separate deduction.
