Frequently Asked Questions
What is trading expectancy?
Expectancy = (Win Rate × Avg Win) − (Loss Rate × Avg Loss). It tells you the average profit or loss per trade. A positive expectancy means you're profitable on average. Example: 55% WR, $150 avg win, 45% LR, $100 avg loss → expectancy = $82.50 − $45 = $37.50 per trade.
What is profit factor?
Profit Factor = Total Gross Profit ÷ Total Gross Loss. Above 1.0 means profitable. 1.5+ is good. 2.0+ is strong. Most consistently profitable professional traders have profit factors between 1.5 and 2.5. Higher isn't always better — it may mean missing good trades.
How many trades do I need to judge my edge?
You need at least 100 trades for meaningful statistics, ideally 200+. Below 50 trades, your results are largely dominated by luck. The more trades in your sample, the more confident you can be that your win rate and expectancy reflect your true edge rather than random variance.
What is a good win rate?
Win rate alone means nothing without knowing your R:R. A 40% win rate with 1:2 RR is more profitable than a 60% win rate with 1:0.8 RR. What matters is expectancy and profit factor. Many professional traders win only 40-50% of trades but have large average wins relative to losses.
