1.MT5 is not an upgraded version of MT4, but it is different. Even their officials say it's not an upgraded version. \x0d\2。 The biggest difference is that MT5 can't hedge (can't hold both long and short positions at the same time), while MT4 can hedge \x0d\3. When trading on MT5, there will only be one order for the same variety in the same direction, and even if more orders are issued, they will be rejected. And every command on MT4 is independent \x0d\4 Other differences, the programming language of MT4 is similar to C, while the programming language of MT5 is C++. \x0d\ It is suggested that the official download MT5 and use the simulated account for simulated trading. \x0d\ You can contact me if you need MT4/MT5 programming.
