Frequently asked questions
What's a good R:R?
Minimum 1:1.5, ideally 1:2 or better. Higher R:R relaxes the win-rate requirement: at 1:3, you only need 25% win rate to break even.
Win rate vs R:R — which matters more?
R:R × win rate together give expected value. High win rate with tiny wins (1:0.5) loses money. Low win rate with big wins (1:5) can still profit.
Why bother with low R:R trades?
Some strategies (scalping, arbitrage) have 90%+ win rates — even at 1:0.5 they profit. But they're hard to scale.
R:R in options?
Different dynamics. Debit spreads have capped reward vs capped risk (ratio ~1:1 to 1:2). Credit spreads flip — small reward, big risk (but high win rate).
