You do not need to win most of your işlemler to be profitable. What matters is the relationship between how much you risk, how much you make, and how often you win — captured in two ideas: risk-to-ödül and expectancy.
risk-to-ödül (R:R)
If you risk 1 to make 2, that's a 1:2 R:R, often written as 2R. With 1:2 işlemler you can be wrong more than half the time and still profit. Thinking in 'R' (multiples of your risk) instead of dollars keeps sizing consistent and emotion lower.
Expectancy
Expectancy = (win rate × average win) − (loss rate × average loss). A positive expectancy means the Sistem makes money over many işlemler, even with a modest win rate. A 40% win rate at 1:2.5 R:R is strongly profitable; a 70% win rate at 1:0.3 can lose money.
Why this frees you
Once you işlem for expectancy across many işlemler rather than trying to win each one, single losses stop feeling like failures — they're just the cost of doing business in a positive-expectancy Sistem. This mindset is the foundation of işlem psychology.
Key takeaways
- risk-to-ödül lets you profit even with a sub-50% win rate.
- Expectancy = (win% × avg win) − (loss% × avg loss); keep it positive.
- işlem for the edge over many işlemler, not for winning each single işlem.
