You just need to double your money every time you bet and if you have the money to go to the end, you always win.
I tried martingale on mt4 - for some time it was really profitable EA but since some moment it started ruining the balance...
Im already done with this strategy when you do tried to apply it either on Forex or Crypto tradings.In regards to my situation it did blow all of my account when im still trading up with
Forex. Volatility will kill you specially with high impact news, one swing of price then say goodbye to your account.I test it out with Crypto and the situation got worst unless if you are doing
manual you can somehow stop further loss than on doing EA.
