INTERPRETATION

- Kelly is a mathematical optimum under strong assumptions; real execution noise makes it aggressive.
- The simulation assumes each trade risks a fixed % of current equity, win adds $R$ multiples, loss subtracts 1R.
- Use this to choose conservative defaults and keep buffers inside your prop ruleset.
