Kelly Calculator

Does anybody here have a good web site that has a Kelly calculator? I am looking for a web site that I can just fill in the percent winning trades and the average win average loss.

Thanks
 
I have not seen one or looked for one, but...why do you need one? By the time you calculate the % return for wins and losses, you are most of the way there:

k = (((1+r)*p)-1)/r

where r = mean % return on wins/mean % return on losses

and p = probability of a win

Assuming you risk the same amount or % on each trade

15rms,

Once you have reduced the information to, "percent winning trades and the average win average loss", only, the Kelly Ratio can no longer be determined.
