Export to MT4/ MT5
When you are done building your EA you can export it. EA Builder Pro will generate an ex4/ex5 (compiled mql) file for you. All you'll have to do is press the "Export To MetaTrader" button and the download will begin.

After downloading the ex4/ex5 file you can use the EA in a backtest, or in a demo- or live environment.
For more information about MetaTrader go to MetaTrader 4 or MetaTrader 5.
