Algorithm::Kelly - calculates the fraction of a bankroll to bet using the Kelly formula
use Algorithm::Kelly; use feature 'say'; say optimal_f(0.5, 2); # 0.25
Returns the optimal fraction of bankroll to wager, using the Kelly Criterion, given the
$payoff. Payoff should be the net odds of the wager, so the value of 3-to-1 would be 3. The
optimal_f() sub is exported by default.
Odds are usually presented in one of three styles: decimal, fraction or American. The
optimal_f sub requires the net decimal odds. These odds are all equal:
Type Example Net Odds ---- -------- -------- Decimal 4.0 3.0 Fraction 3/1 3.0 American +300 3.0
The different odds representations are also explained here.
