DislikedI was using a counter trending Martingale EA for many months, until fairly recently. After taking a couple of big losses that went beyond Level 7, I lost my enthusiasm for the principle. The more pairs you trade; the more money you will make. However, the more pairs you trade, the greater the chance that one of them will turn around and bite you.
I still believe that such a system can be profitable but, have never been able to come up with a solution to counteract the potential death trade(s).Ignored
For example if in the last ten years your system never reachs lvl 10, then you should only run a live account that can hold until lvl12.
The bad thing is that a martingale system that can hold until lvl10 will start with 0.01 lots, and you need really high ammount of trades per day to make it profiteable.
