Not heard his name mentioned for a while, I read Fortunes Formulas by William Poundstone when I was 15, I think its a massively underrated book. It goes into Kelly quite a bit,
So you mean do people trade risking only 2% of their capital at a time?
This would be extremely limiting on a small account, and in high risk ventures like futures I think you would be struggling to hold any position for any length of time.
