Quote from oilfxpro:
One of the ways to beat the market day trading is through martingale type (not martingale itself)position sizing , using 50 /50 success rate set ups, and recovering previous losses through a sophisticated betting method , a method which can survive 75 consecutive losses
This in theory works and by using it , day trading can be very profitable.
I don't understand this, if you have a method that gives you 50% winners, the probability of having 75 consecutive losers is 3.77 x 10 ^22
It's possible to have 10 losers in a row , but if you had say 20, you need to re-evaluate your method, because your assumption of your method having a 50% win rate is likely to be wrong.
