Re: Chances of breaking even
[ QUOTE ]
Can someone help me calculate the chances of breaking even or losing over an extended period of time for a given WR and SD?
I vaguely remember a post with the formulas here in the past, but I can't seem to find it using the search function.

EV (after x hours) = EV*x
SD (after x hours) = SD*sqrt(x)
Probability of breaking even or being behind is N(-EV/SD), where N is the normal distribution.
So, it's N([-EV*x]/[SD*sqrt(x)]), or N([-EV/SD]*sqrt(x))
The easiest way to solve is by using the <font color="green">=normsdist()</font> function in Excel.
