I can't really remember the last time I used stop loss in a trade, I just make sure I don my analysis well then I enter a trade. Mostly whenever I enter a trade and I use stop loss, immediately my stop loss have been hit, then the coin will bounce back that's why I don't really use it again, I always make sure I monitor my trade myself and I always know when to leave a trade.
Okay I presume that you exit your trade yourself when it is moving opposite your desired direction and you can't afford to lose all to stop loss ? Because I know that all traders lose some and win some. This time when you are not trading with stop loss, take for example your computer become faulty when you are in a volatile trade without stop lose? This you can lose all that would have been protected by stop loss. Anyway like you said every trader should learn a strategy that is working for them but remember stop loss was not designed because of newbies alone, even experienced trade use stop loss.
