Risk-Reward Below 1:1 Needs a Very High Win Rate to Survive

[Fairman]

A lot of scalping setups target 1:1 reward-to-risk, or sometimes even less — grabbing 5 pips while risking 7 or 8, for example.

That's not automatically a bad approach. But it only works under one condition: your win rate has to comfortably clear somewhere around 55-60%, after accounting for spread and commission.

Here's the math intuition. If you're risking exactly what you're targeting, you need to win more than half your trades just to break even, and meaningfully more than half to actually profit once trading costs are subtracted.

This is where a lot of scalpers get quietly destroyed without realizing it. They track their win rate loosely, feel good about "mostly winning," and don't notice that their real, cost-adjusted win rate barely clears breakeven. Weeks go by feeling productive while the account slowly drains.

The fix is simple but requires honesty: track your actual win rate, including cost-adjusted outcomes, over a meaningful sample size — at least 50-100 trades.

If your R:R can't support your win rate, or your win rate can't support your R:R, the strategy is mathematically losing money slowly, even during weeks that feel like "good weeks."

Feelings are not P&L. Only the spreadsheet tells you the truth.
