Converting a simple indicator to from MQL4 to MQL5

Hi everyone, I need to convert an indicator from mql4 to mql5. 

The indicator is just a group of moving averages calculated on a main linear regression line. The total indicator is composed by two separate indicators and one include file, the total indicator is splitted in two indicators indeed but the total code is very short and simple, hence the price request. 

The converted indicator must be 100% identical, no change in parameters, colors or method of calculations. I know how to code in mql4 and I assure it's a really simple code, it's just me that I don't have time to learn the differences between mql4 and 5. 

Thank's for your attention.
