Beginners worship win rate. Marketers know it — hence every scam Telegram channel screaming "92% accuracy!" Here is the uncomfortable truth: win rate alone tells you nothing about profitability.
The two systems
System A wins 90% of trades — grabbing +0.2R winners, holding losers to −3R ("it always comes back… until it doesn't"). Net: negative. System B wins 40% — losers cut at −1R, winners averaging +2.5R. Net: strongly positive. The first feels wonderful daily and bleeds out monthly; the second feels mediocre daily and compounds yearly.
The only equation that matters
Expectancy = (Win% × Avg win) − (Loss% × Avg loss). Positive expectancy compounds; negative expectancy destroys — regardless of which component looks pretty. Full treatment in What Is Expectancy.
Psychology picks your profile
Low win-rate/high-R systems demand you shrug through long losing streaks; high win-rate/low-R systems demand ruthless loss-cutting because one bad hold erases twenty wins. Neither is superior — but one fits your temperament better, and the mismatch is where discipline actually breaks. Most structure-based trading (ours included) lives in the balanced middle: roughly 45–60% wins at 1:2 or better.
The takeaway
When someone advertises accuracy, ask for average win and average loss in R. Silence answers the question. Our track record publishes net R for exactly this reason — it is the only honest scoreboard.
Education only — not financial advice. Trading carries risk of loss; never trade money you cannot afford to lose.
