[FONT=NotoSans, Lato, arial, sans-serif]It is not necessary to know the type of poker you play to determine the rules for bankroll management.
You need to know your statistics at a sufficiently large playing distance. It is enough to find out a few parameters in some poker tracker.[/FONT]
There is an absolutely exact bankroll formula that works for all poker formats.
You yourself can choose what risk of ruin is acceptable for you, for example 5%, 2%, 1%, ...
B = (D / 2m) * ln (1 / R)
B - bankroll
m - winrate (expectation)
D - variance
R - risk of ruin
For example, for a cash games with a winrate of 7.5BB / 100 and a variance of 100^2 BB^2 / 100, choosing a ruin risk of 5%, we get:
B = (100 * 100/15) * 3 = 2000BB
{ ln(1/0.05)~3 }
Everyone knows the rule of 20 stacks...
You can also calculate for SnG, knowing your winrate and standard deviation over a long distance.
