For comparison here are two backtests with USDJPY, beginning lot 0.1, one with martingale multiplier 2.0 and the other one with multiplier 1.2. Test is from 2017.01.09 thus far. 2.0: image image Max lots 25.60 1.2: image image Max lots 1.03 Considering that the maximum lots with MG 2.0 is being hit just once and even 3.2 lots just a few occasions, it'd probably make sense to limit the maximum lots to around 3 in order to decrease DD. However, with all the multiplier 1.2 you could use a greater initial lot and still keep the DD relatively low.
