You should learn not to utilize stoploss but understand where your exit are. When you trading on ecn, the spread can be volatile particularly during news and asian session where bandwidth are reduced. And just stick with major pair, which is usd pair but dont trade exotic usdpair like usdtry,usdsek,usdzar etc the spread may go crazy too and try to not trade cross pair that's everything without usd onto it. Because when you trade cross pair the spread may get even worst.
