The UltimateChannel2 pdf comes with Pinescript code for TradingView and I can't imagine it would be too difficult to convert it into MQL4/MQL5 code.

I'm sure PineCodersTASC on TradingView will eventually publish the code since they do so for every monthly magazine's featured indicator, but I've included the code to Ehler's Ultimate Smoother that was published in the April 2024 issue.

Hopefully that makes things easier for you!
