The Scientific Gambling Method


The Kelly Formula (Criterion) determines mathematically optimal allocations in order to maximize long-term portfolio performance given an investment’s probability of success compared to the amount gained or lost. It results in the maximum expected rate of bankroll growth, and is the optimal strategy for money management in betting games.

The Kelly Formula

Kelly % = W – (1-W)/R where:

  • * Kelly % = percentage of capital to be put into a single trade.
  • * W = Historical winning percentage of a trading system.
  • * R = Historical Average Win/Loss ratio.

"A trader whose trades show a Kelly percentage that is less than zero, has no business trading at all"
