There’s no single “good” win rate — it depends entirely on your reward-to-risk. A 40% win rate can be highly profitable with big winners; a 70% win rate can lose money with big losers. Win rate alone is meaningless.

Why win rate alone lies

What matters is expectancy — win rate combined with the size of wins vs losses. A 40% win rate with 3:1 winners is very profitable; a 70% win rate with tiny wins and a few big losses is a loser. So “good” depends on your average R. Chasing a high win rate for its own sake often means cutting winners short, which wrecks expectancy.

How to think about it

Decide your style: high-win-rate/small-winners (mean-reversion, quick profits) or low-win-rate/big-winners (trend, let runners run). Both work if the math is positive. A scalper taking quick profits might run 55–65%; a runner-focused trader might run 40–50% and still crush it. The “good” number is whatever gives you positive expectancy at your reward-to-risk.

There’s no magic win rate — only the win rate your reward-to-risk needs to be profitable. Optimize expectancy, not the hit rate.

What it means for a scalper

Track expectancy, not just win rate, in your journal. Don’t sacrifice big winners to inflate your win rate. Know which style you trade and what win rate its math requires. A “low” win rate with great winners is a fine business.
