Displaying average zigzag-leg-distance in points and bars // seperate for up- and downtrends

Hi, i need a lightweight indicator, that can be used on around 30+ fx pairs at the same time. The indicator should be addible multiple times on the same chart calculating different timeframes.

My idea is inspired from ATR Value Indicator: https://www.mql5.com/en/code/21175. But instead of displaying a multiplied ATR value, i would like to display average zIgzag leg-lengths in points AND number of bars, to find the right stoploss.

So the indicator should count distances and bars for every ZigZag leg from the past n bars (input parameters). The output should be seperated in uptrending and downtrending leg-distance points and bars and merged together at the end of the list (see below). 

Lets say that the indicator counts 15 up- and 15- downtrending legs, so it should count these seperate leg-distance points and bars and divide these with 15 to get the average leg-length.

Example for displaying in M15 Chart (GBPNZD) with setting ZZ_ExtDepth = 40: 

Values with example input parameters (inputs should be free to choose):
