An SL should not always be used when your trading. If you are for example trading very small lot size and
your equity can handle it, then try better to martingale! Please use martingale strategy only when you have
enough equity and trading small lot size. Or it will kill your account for sure!
The problem of some traders are that they set the SL wrong! Always set it under the support and above the Resistance!
But why not always using SL? Because I had personally many trades with 100 pip and more and the price returned to my SL @ BE.
I let the profits always run, so I can make 200 -300 pips in a trade. I dont close them completly.
My Motto always: Dont hope in trading, dont fear the loss in trading.
