DislikedYes, stop loss is necessary , especially while trading equity and commodity markets. In forex most of the time stop-loss get triggered and I use stop loss if I take trade against the trend . However there is no robust rule for that and stoploss never guaranteed by broker and can't protect ourselves from market debacle like Usd/chf (recent) crash. As when there is 3000+ pips drop and price open and close in Gap we can't guarantee our limited loss. But still stoploss is important.Ignored
