Setting a suitable stop loss point can not only help us get as much profit as possible, but also help us avoid greater trading risks even in a relatively dangerous market. However, the market tends to fluctuate to varying degrees, and a fixed stop-loss point will certainly not help us get more profits. At this time, the mobile stop loss function in MT4 is particularly important. The MT4 platform has this important function. Mobile stop loss, also called trailing stop, means that trading software can adjust the position of stop loss point according to the latest price position and price trend, and this function will only be triggered when the market is favorable to this position. This function can ensure that investors' income will not be reduced under the premise of correct investment direction, and the profit point is fixed. The moving stop loss in MT4 needs to be set manually in the opening menu of the software, but it is worth noting that our MT4 software can only set one moving stop loss point for a position. However, some investors have expressed concern that the stop loss of the moving stop loss point is triggered according to the direction of the exchange rate that is conducive to holding positions, and will not follow any important position in the exchange rate trend, which means that the moving stop loss may cope with the technical support resistance, destroy the established resistance point in the transfer process, and bring greater risks to the transaction. At this time, you can also choose to check the current market changes and manually set your own stop loss point.
