Colored Zerolag MACD - indicator for MetaTrader 5

This is the MQL5 version of ZeroLag MACD that was available for MetaTrader 4 here: https://www.mql5.com/en/code/9993

Also there was a colored version of it here but it had some problems: https://www.mql5.com/en/code/8703

I fixed the MetaTrader 4 version which has 95 lines of code. It took me 5 days to write the MetaTrader 5 version.(reading the logs and testing multiple times and finding out the difference of MetaTrader 5 and MetaTrader 4!)

My first MQL5 version of this indicator had 400 lines of code but I optimized my own code again and now for reading all of the history it has around 290 lines of code!

In My first MQL5 version of this indicator I used IMAonArray from MetaTrader 5 site and it used to take 8 seconds to load for the first time for calculating 700 candles!

As MetaTrader 5 does not have iMAonArray and the code iMAOnArrayMQL4 from https://www.mql5.com/en/articles/81 has some loops with too much cycles, so I rewrote it.

Also the time series in MetaTrader 5 is from old to new candles (from left to right) but in MetaTrader 4 the time array is set as timeseries by default, so it is from new to old (right to left). As the MQL4 version of the indicator was coded somehow that I couldn't simply set arrays as timeseries (change their direction) and get the correct results in MQL5, so I had to change all the loops and write my own method to calculate all the candles of history for this MetaTrader 5 version.

As the original code was free, I will share product for free in market too. hope it will be useful for getting faster signals than the traditional MACD.
