1. Stop loss after the important support level or resistance level is broken. This is the most commonly used operation mode in actual combat. According to my observation, the proportion of investors who stop at this position is very high. However, a careful analysis of foreign exchange charts at home and abroad shows that in the foreign exchange market, the price trend often reverses after the resistance level or support level is broken. The important resistance or support positions are as follows: (1) the intensive transaction area where the price stays for a long time; High or low prices for a long time; Location provided by trend line, golden section or moving average system. 2. Stop loss after the absolute amount of loss is reached. At present, this is a stop-loss method adopted by many foreign gamers. The key point of its operation is that the maximum loss of funds for setting up entry points is generally 5%-20% of the occupied funds, or it can be the absolute amount of occupied funds, such as 100 yuan per lot. Once the loss amount is reached, stop the loss immediately, regardless of the price. 3. Stop loss after reaching your tolerance limit. This stop loss method is often used by novices. The author's experience is that using this stop loss method in short-term operation is still helpful to improve the yield. In fact, some excellent foreign exchange traders often use this method.
