no - if you hit 50% you are stuffed, period. I don't know what the point of no return is, but 50% has to be well past it - at this point you have to figure that something is seriously wrong with your trading strategy. What i am saying is, if you have 100k, and you apply the 2% rule, and you lose, then you have 98k left. Don't now apply the 2% rule to the 98k, because if you lose again, you will have 96.xK left. Now if you win on try 3, (assume your target is 2*risk) then you will only recover 3.x%, not 4% - which puts you at less than starting, and you will now be in a vicious circle. Remember that your system is a function of risk vs reward as well as the ratio of wins to losses. If you downsize your position on losses, then you introduce a 3rd factor - the sequence of events. And the first two give us enough headaches to worry about
