FAQ
Questions Kelly Criterion Strategy owners ask.
- 01
What is the Kelly Criterion?
The Kelly Criterion is a formula used to determine the optimal size of a series of bets to maximize the logarithm of wealth, balancing win probability against the reward-to-risk ratio.
- 02
Why does the server use Half-Kelly sizing?
Half-Kelly is a conservative approach that halves the theoretical Kelly percentage. This reduces volatility and provides a margin of safety against errors in estimating win rates or win/loss ratios.
- 03
How is the maximum position size limited?
To prevent over-concentration, the server automatically caps any single position at 25% of your total available capital.
