Even if you start with 0.1 lot it doesn't work. Following 10 losses in a raw you will wind up with over 200 lots ! I let you figure out what your funding should be to open 200 lots.
Anyhow there are plenty of unique variations of martingale Ea in the forum and it is also the prefered EA for crooks to market it to newbies.
Because it looks good on the statement for a few days/weeks/maybe months if you're fortunate and have a huge funding but it always ends the same way: the account is wipped out
Just my advice: do not spend too long trying to work on a martingale EA. When it would work, we would all be billionnaires. There are loads of egies in this forum that are much more interesting to research and to comprehend.
