It is better not to think that Stop-Loss is a loss, but think of it as a cost for the mistakes made. A kind of school or college fees, as a form of warning that traders need to improve their abilities. The price movement touching the SL point should be considered as the cost of learning, this cost arises because you cannot properly compile the analysis. If later you have succeeded in compiling the analysis correctly, there should be no need for school fees. Instead, you always get of money from the analysis.
