Converting MQL5 Code to MQL4

 
Hello.. I've just started trading, and I'm looking for a an AO Crossover EA. I found and copied one from a video on youtube but it isn't compiling properly in the mql5 metaeditor. I would like some help fixing it, and then if possible converting it to mql4, because that's where my trading account is. Thanks.
 
If no one helps on this thread so you may consider to use Freelance for example.
 
  1. You can't compile MT4 code in the MT5 editor. You need to download and install MT4.
  2. Furthermore, you need to learn the language and translate the MQL5 code appropriately. E.g. iAO does not return an int.
