How it works
What exactly does the simulator do?
It block-bootstraps your pasted trades into 3,000 alternative orderings of the same performance, then runs each one against the selected challenge rules (daily loss, max loss, profit target, minimum days). The share of paths that pass is your estimated probability — from your own numbers, not a generic calculator.
Why not just look at my equity curve?
One curve is one lucky (or unlucky) ordering of your trades. Challenge rules are path-dependent: the same trades in a different order can breach a daily-loss limit that your live curve never touched. Resampling exposes that hidden risk.
Is my trading data uploaded anywhere?
No. The whole engine is a small JavaScript module running on your device. You can open your browser's network tab and verify: no requests carry your data.
What should I paste?
One closed-trade result per line in account currency (exports from MT4/MT5, cTrader or a spreadsheet column all work — extra columns and headers are ignored automatically). 50+ trades give a stable estimate.
