calling mq4 from C#/C++/Java

[Josip Istuk]

Hi, how can I call mq4 from my c/c#/c++/Java program? I need call functions like iRsi(...), iMACD etc.

implementation of such indicators in MT is not ideal, hence it is hard to understand why you want to use indicators provided exactly with Meta Trader, so at the moment i can suggest only such options :

1. [EASY WAY] there are several open source libraries that provide much wider list of different indicators, thus i would recommend to look at implementation of such indicators in R studio, you can call different R methods from your C# code

2. [HARD WAY] you can create custom EA in MT and using e.g. Named Pipes exchange some information between this EA and your C# program, when it is already implemented then you will be able to send commands from C# to EA, e.g. dynamically add some indicator to the chart
