Your trading stats

Win rate (%) Out of 100 trades, how many do you typically win

Win rate variability (%) How much your win rate varies. 5 means it swings 5% either side — so 55% becomes anywhere from 50%–60%

Risk:Reward ratio If you risk $1 and win, how much do you make? e.g. 2 = you make $2 per winner

Worst losing streak ever The longest run of consecutive losses your strategy has had — from backtesting or your journal

Max trades per day The most trades you take in a single day

Simulation runs More runs = more accurate. 1000 is a good balance of speed and accuracy
