I understand the intention to use stop loss with long trading is that we hope that breaking through this level will further indicate a better level for good friends, so the main reason we have to trigger a stop loss is the high leverage we use. This only means that those who use lower leverage don't have to worry about stop loss. and Stop loss is also a useful tool for conducting Forex trading business safely, if we want to do business properly then we must set a stop loss tool at the right point, I think if we calculate the support and resistance levels correctly then we can set stop loss and take profit tools correctly.
