Stop Loss is a good tool and by using it you can control your loss. It prevents you from big losses and margin calls. But i think it is not so easy to put SL. It is just like TP if you decide your TP with deep analysis then SL is also set by deep analysis. If u dont use the tool then ur account will blow off. Always place stop loss double ur take profit. if u place take profit for 50 pips then place stop loss for 100 pips...
