PORTFOLIO SIMULATOR
Multi-position binary-market sizing. For each row you input a model probability qand the engine computes individual Kelly, then applies a correlated-Kelly haircut from the empirical correlation matrix of price returns across the basket. A book-walk simulator estimates the slippage of the resulting clip sizes against the available liquidity. Honest about each piece's sample size — many PM histories are short.

Correlation matrix (price returns)
Note: PM price histories are typically short (n < 60). Correlation estimates here have wide standard errors; treat the matrix as directional, not precise. The haircut is conservative for small N — closer-to-zero correlations imply larger individual Kelly fractions than the data may justify.
