I know about the deadly martingale but what I am saying is that you never had martingale that double the size of the loosing sequance.
I think that if Funyoo will code it we will know if it is visible. and if yes, you can use it as an option on any EA.
If you look at the report of Heiken Ashi EA he got to trade with 23.68 lots which is very poor risk reword.
If you had the hedge in between you had only 1.6 or 3.2 lots
BTW I think that 20% monthly is not realistic.
I shoot to 100% yearly with low risk and I am almost there.
