TRADING PERFORMANCE GLOSSARY

Average win vs average loss

Average win is total winning value divided by winning trades. Average loss is the absolute total losing value divided by losing trades. Their relationship is often called the payoff ratio.

THE FORMULA

Payoff ratio = average win ÷ average loss

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

WORKED EXAMPLE

See the calculation.

Average wins of $200 and average losses of $100 produce a 2.00 payoff ratio. The break-even win rate before costs is 100 ÷ (200 + 100) = 33.33%.

HOW TO INTERPRET IT

Ask what the number leaves out.

Use net outcomes when you want costs reflected in the comparison.
Averages can hide skew and outliers, so inspect the distribution and largest trades.
Payoff size and win frequency work together; neither is a complete performance measure.

COMMON MISTAKES

Keep comparisons honest.

Entering average loss as a negative magnitude in a formula that expects positive loss size.
Combining unrelated setups or instruments.
Assuming the average stays constant as execution or market conditions change.
