The stop loss point you need to set for the long term is very large, usually around 150, and the retracement of funds will be large. This depends on whether you can accept the floating loss psychologically. For example: you place a standard lot of EURUSD with a leverage of 200:1, a 10% position, a stop loss of 150 pips, a margin of 700 US dollars, and a maximum floating loss of 1,500 US dollars. Your investment needs to be about 7,000 US dollars. Only then can complete risk control be achieved. If your capital is small, your position may be liquidated and forcibly liquidated before it reaches the stop loss point. Although the risk is high, if you control your position correctly, wait for a good entry position, and strictly operate your skills, the risk is controllable. The foreign exchange market exists every day, and survival is the first priority.
