pozisyon sizing is how SEN translate a işlem idea into an exact number of lot so that a loss costs a fixed, planned amount. It is the single most practical skill in risk management.
The percent-risk model
risk a small, fixed percentage of your hesap per işlem — commonly 0.5% to 1%. On a $5,000 hesap, 1% is $50. Every işlem is sized so that hitting your stop-loss loses about that amount, no daha.
The sizing formula
pozisyon size = (hesap × risk %) ÷ (stop distance in pips × pip value). If your stop is 25 pips away and a micro lot's pip value is $0.10, then $50 of risk ÷ (25 × 0.10) = 20 micro lot. Wider stops mean smaller size; tighter stops allow larger size — same money at risk either way.
Why fixed-percent survives
Risking a fixed percentage means your pozisyon shrinks automatically during a losing seri (each loss makes the hesap, and so the next pozisyon, smaller) and grows as SEN recover. It mathematically prevents the death spiral of risking daha to win tekrar losses.
Key takeaways
- risk a fixed small % (0.5–1%) of the hesap per işlem.
- Size = (hesap × risk%) ÷ (stop pips × pip value).
- Fixed-percent sizing shrinks risk in drawdowns and prevents the death spiral.
