Modify Existing Source Code so that it Matches indicator values

I have the source code attached which is my attempt at merging / converting:

Into MQL5 code, but instead of being an indicator I just need it to return the same values as the indicator.

What I need help with:

I need the values in the comments to return similar to the demo indicator below - currently it is showing values near the price, but would instead expect - values from -80 to 80 like the indicator

How to test:

- Make sure the attached source code WaveTrend, returns the same value output as https://www.mql5.com/en/market/product/88437?source=External# which using the same inputs

Example:

Comment(
"HLC3:  ",HLC3,"\n\n",
"wt1:  ",wt1,"\n\n",
"wt2:  ",wt2,"\n\n" 
);

These values should match:
