FAQ
Questions Kelly Criterion Optimizer owners ask.
- 01
How does the position sizing cap work?
The server enforces a hard 5% cap on any single bet. Even if calculate_kelly_position suggests a larger amount, the recommended bet size will never exceed 5% of your current bankroll.
- 02
What is the difference between Full Kelly and Half-Kelly?
Full Kelly uses the raw mathematical fraction. Half-Kelly uses a safetyMultiplier of 0.5, which reduces the bet size to half of the full Kelly amount to decrease volatility and drawdown risk.
- 03
Can I simulate long-term outcomes?
Yes, you can use simulate_strategy_performance to run a simulation of consecutive bets to estimate your expected growth rate and the probability of a 90% drawdown.
