This looks more like grid than martingale to me because with martingale strategies the lot size will keep increasing each time a new trade is placed and that's not what really what i saw happening with this EA. To me this EA placed trades at certain level which look more like some kind of grid trading strategy or so. I don't know, maybe I'm wrong about this too.
Anyway, not sure whether this is suitable for trending market or not. I guess only time would tell us more details and info about it. Or if anyone else knows anything please do feel free to share your experience or info with us all. For the time being, I think it's better to use demo accounts only for your best safety. Play around with the settings to see how it works and find the ones that suit you the best. Learn to manage your risks so that your profits could possibly be more secure in the long run. Be safe and stay safe as always. Take care everyone and God bless.
