Hi, backtest looks good. Suggest you put it in demo and run it.can withstand long trending with a bit of tweaking.
Unless your pocket is deep, I realise that whenever a martingale EA is used, it will be prudent to just use 1 or max 2 pairs of currency. No point to use so many pairs as our objective is to make money and to run the demo as if it is real account.
Mind to share what have you changed? I only changed the trading time, the rest default setting.
Cheers...
