How to add mql4 syntax file into your vim configuration:
First, clone this repository to your local.
$ cd ~/.vim/
$ git clone https://github.com/vobornik/vim-mql4.git
It's also ok that download zip file and extract that.
Then, open your .vimrc file and write a following line to add it to runtimepath.
set runtimepath+=expand('~/.vim/vim-mql4')
I recommend to use plugin-manager plugin like NeoBundle or Vundle.
