Sports Perpetual software calculates the optimal bet size based on a a mathmatical formula called The Kelly Criterion

Kelly Criterion

There are two basic components to the Kelly Criterion:

  1. Win probability - The probability that any given bet made will return a positive amount
  2. Loss probability and Edge % - The expected advantage over fair value divided by the probability of losing

These two factors put into Kelly's equation:
Kelly % = W – [(1 – W) / R]

W = Win probability
R = Profit/loss ratio
Kelly staking can be applied at different levels depending on the algorithms variance tolerance
