This MCP server provides mathematical precision to trading capital management. It uses the Kelly Criterion to determine optimal position sizes based on your strategy's win rate and win/loss ratio. By applying a Half-Kelly safety buffer and enforcing a 25% concentration cap, it helps prevent over-exposure while maximizing long-term growth. Use calculate_kelly_sizing to find your optimal allocation, evaluate_trade_parameters to generate specific entry and exit instructions, and analyze_strategy_expectancy to evaluate your edge and risk of ruin.

Calculate my position size for a strategy with a 55% win rate, a 2.0 win/loss ratio, and $50,000 in total capital.

Your optimal Half-Kelly position size is $5,500.

I have an entry price of $150, a stop-loss at $145, and a take-profit at $170. My allocated position size is $10,000. How many shares should I buy?

You should purchase 66.67 shares.

What is the expected value and risk of ruin for a strategy with a 40% win rate, $500 average win, and $400 average loss?

The expected value per trade is $20, and the estimated risk of ruin is 0.02%.

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.
