We need to install Wine first. This is allowed us to launch Windows software under Linux.
Let's open the Terminal and call the commands.
yum install wine
And now, get winetricks
wget http://kegel.com/wine/winetricks
chmod +x winetricks
sudo mv winetricks /usr/bin/
Then install requirements for MetaTrader using wineticks:
winetricks gecko vcrun6
Thats all! Now we can install and run MetaTrader like Windows.
Note: Tested on CentOS 5.4 and CentOS 5.5.
