There are two ways for me in automated trading :
1 - algorithms that deal with SL and let it hit.
2 - algorithms that use technical SL - far away from opening price - and let the SL almost NOT hit. Internal SL or methods will close almost earlier than technical SL.
Not every algorithm/strategy can deal with 1 AND/OR 2. The more you invest in quality of exit signal the more you can risk as in 2. To be safe with 2, you need to know brokers tickvalue, the risk you will take in sum and a good exit criterion.
I quit method 1 for myself. Hitting a fix SL is just lack of exit signal and hard exit by loosing orientation. I don't like this. Visibile tight SL are just to easy to grab for your broker with a single tick hitting gently yout tight SL. My development EA Cutter uses wide technical SL. And yes it will be hit in backtest, but money management and a good exit algorithm allows me to use this anyway (hopefully).
