Win rate vs risk/reward: which matters more?
Neither matters alone. What matters is that Win Rate x Avg Win exceeds Loss Rate x Avg Loss. A 1:2 R/R only needs a 34% win rate to break even; a 1:1 R/R needs 50%.
The break-even relationship
Break-even Win Rate = 1 / (1 + R/R). So a 1:1 R/R needs 50%, 1:2 needs 33.3%, 1:3 needs 25%, 2:1 needs 66.7%. Any win rate above the break-even for your R/R is a profitable edge before fees.
Break-even Win% = 1 / (1 + R/R)
Why chasing 'high win rate' is a trap
Strategies that hit 80% win rates usually take tight targets and let losers run, producing a low R/R. One outsized loss wipes out ten winners. Expectancy exposes this immediately.
Why chasing 'big R/R' is also a trap
A 1:5 R/R sounds great, but if your win rate is 12%, expectancy is barely positive and drawdowns are brutal. Both dials matter.
How to find your real balance
Log every trade in a journal, group by setup/tag, and compute expectancy per setup. Keep the setups with positive expectancy, drop the rest. That is edge discovery in one sentence.
Frequently asked
Is a 1:2 risk/reward always better?
Only if your win rate stays above ~34%. Below that, 1:2 loses money.
Can I have a 90% win rate strategy?
Yes, but almost always at a poor R/R (like 1:0.3). Verify with expectancy, not win rate alone.
