H1 timeframe.
And some changes in the settings:
Stop Loss = 100;
Take Profit = 100;
Trailing Stop in pips = 15;
Trailing Stop Step = 5;
Brekeven in pips = 25;
Profit Lock in pips if ... = 10.
Conclusion: M15 timeframe is not profitable or profitable just for few pairs only. H1 timeframe is profitable for now (till now) for all the account/pairs.
