How to Calculate Your Trading Win Rate (and Improve It)

Win rate is the most quoted — and most misunderstood — statistic in trading. Here is the formula, what counts as "good," the trap almost everyone falls into, and how to track it without a spreadsheet.

The formula

Win rate = winning trades ÷ total trades × 100

Close 50 trades, win 30 of them: 30 ÷ 50 × 100 = a 60% win rate. Count only closed trades, count break-even trades consistently (either exclude them or define a threshold), and never count open positions — hope is not a result.

What is a good win rate?

Trick question. A 40% win rate can be wildly profitable and a 75% win rate can slowly bleed an account. It depends entirely on the size of your average winner versus your average loser:

• Trend followers often win 35–45% of trades but their winners are multiples of their losers.
• Scalpers may win 65–80% with small winners — until a few outsized losses erase the edge.

The number that ties it together is expectancy: (win rate × average win) − (loss rate × average loss). If that is positive, your system makes money; if not, no win rate will save it.

The sample-size caveat

A win rate from 8 trades is noise. Treat 20 trades as a first hint, 50+ as a real signal, and always compare like with like — your win rate per setup or per market matters more than the blended number.

Tracking win rate automatically

Calculating this by hand is exactly the kind of maintenance that kills journals. AlphaTrades computes it for you: the analytics screen shows a win-rate ring with wins and losses for any week, month or year, alongside average result, best and worst trade, and long vs. short splits. Log the trade — by voice, photo or a quick form — and the math is done the moment you save.

How to actually improve your win rate

1. Get 20+ trades in the journal so the number means something.
2. Segment: win rate by setup, by weekday (profitability heatmap), by direction, by market.
3. Stop taking the trades that lose. Improvement usually comes from subtraction — cutting the Friday trades, the revenge trades, the one pair you should not touch — not from a new indicator.
4. Re-measure monthly. Your win rate becomes a feedback loop instead of a mystery.
