TRADING PERFORMANCE GLOSSARY

Trading win rate

Win rate measures how frequently trades finish profitably in a defined sample. It says nothing by itself about the size of wins, losses, fees, or risk taken.

THE FORMULA

Win rate = winning trades ÷ total closed trades × 100

Use consistent units and state how breakevens, fees, and incomplete trades are treated.

WORKED EXAMPLE

See the calculation.

With 24 winners, 14 losers, and 2 breakevens, overall win rate is 24 ÷ 40 = 60%. If breakevens are excluded, decisive win rate is 24 ÷ 38 = 63.16%.

HOW TO INTERPRET IT

Ask what the number leaves out.

  • State whether breakevens remain in the denominator.
  • Pair win rate with average win, average loss, expectancy, and costs.
  • Compare consistent samples and avoid treating an arbitrary target as universal.

COMMON MISTAKES

Keep comparisons honest.

  • Counting open trades as outcomes.
  • Changing breakeven treatment between periods.
  • Optimizing win frequency while ignoring loss magnitude.
