I moved to mql4 and mql5 programming language. But, MetaEditor is very noob to code with, so I want to code mql4 language and compile with VS Code. If you have any solution please share with us..... Thanks

In the very early years of MQL4 ( MetaTrader Terminal, versions in about 2008-2010 ), there was a separate compiler programme, thus was configurable into other IDE ( me, using Geany-IDE ecosystem for doing this since ever ) After MQL4 language-revision, somewhere about 2009-2010 iirc, this option ceased to exist. Inside MQL5 ecosystem, this option was available never. The maximum achievable comfort thus remains in code-syntax highlights, code-completion configurations, if doable & done manually for the sake of your individual preferences ( me, using Geany-IDE ecosystem, being happy with MQL4-language configurations ( revised whenever MQL4 took further language specification revisions ) & copy/paste "technology" or #include -trick for moving between the two distinct ecosystems )

There is a Extention(Plugin) in the VS Code called "MQL Tools", that can make you very easy to code MQL4 or MQL5 language , and compile with VS Code. You should try it.

If you open the Extensions tab and filter on MQL4, you'll find a MQL4 Syntax Highlight extension that also works for MQL5, and you'll find a MQL Tools extension that will add compilation options to VSCode. Works perfect!
