The Kelly Criterion

The Kelly Criterion

The Kelly Criterion is a formula used to determine the optimal trade size to maximize long-term growth. It weights your win rate against your average win/loss ratio.

Warning

Pure Kelly sizing is notoriously volatile. Most professional traders use "Fractional Kelly" (e.g., 0.25 * Kelly result) to lower the swings.

FAQ
