Mt4 cannot be traded, mainly because investors failed to log on to the mt4 platform. Main reasons and solutions: 1. Wrong server selection. Wrong server selection is a common reason why you can't log on to mt4 platform. Almost all foreign exchange retailers use Mt4. Not only do different retailers use different servers, but some large retailers even have multiple servers. If investors choose the wrong server, they will not be able to log in to the server, which will make the mt4 platform unable to trade. Second, there is something wrong with the network. After logging in to mt4, investors can check whether there is traffic in the lower right corner of the platform. If there is an explanation, it is another problem. They need to check the network if they don't explain that the network settings are wrong. Third, foreign exchange is closed on weekends and some holidays, and it is impossible to trade when logging in to the mt4 platform. Download address of genuine MT4: http://mt4. M 1 .sinklow.xyz/
