Sen do not need to win most of your işlemler to be profitable. What matters is the relationship between how much SEN risk, how much SEN make, and how often SEN win — captured in two ideas: risk-to-ödül and expectancy.
risk-to-ödül (R:R)
If SEN risk 1 to make 2, that's a 1:2 R:R, often written as 2R. With 1:2 işlemler SEN can be wrong daha 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 SEN
Once SEN 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 SEN profit even with a sub-50% win rate.
- Expectancy = (win% × ortalama win) − (loss% × ortalama loss); keep it positive.
- işlem for the edge over many işlemler, not for winning each single işlem.
