SL is really needed, whether it's a trader with scalping style and also long-trem trading without SL, of course it will make us feel uneasy and worried. In my opinion, the way to respect losses is that every loss is hit by SL, we record it every day, so we can know at the end of the day. where is the error that makes us always trading with SL, we calculate the opportunities when we get SL, if we evaluate it, we have to learn from losses that have a lot of discipline in order to enter the market correctly
