More details on Kelly Criterion https://en.wikipedia.org/wiki/Kelly_criterion
I must confess, the criterion is a little more than i can take in and utilize, but certainly interesting. I'm told of one trader who swears by Kelly Criterion, enjoys 87% win rate and claims $100k per week average profit.
The hardest part with the Kelly criterion is gettin' the numbers right.
There are many wizards that do use this criterion for bet sizing.
We're told to bet half of it because for safety reason.
It's better to under bet than to over bet ^^
In the end it does just maximize growth over time.
If you don't know how to use it then bet a fixed %
Less than 2.5% is a good one to bet with.
