TheLark: Laguerre PPO

A while ago I posted a more flexible MACD , known as PPO (See that post for details).
Yesterday I had a request by @ChartArt for a Laguerre MACD . Since I favor PPO to MACD , here it is!

Completely untested, and not at all price fit. Play with the numbers and leave a comment if you come up with an interesting combination or idea ;)

Hello there, TheLark! I'm trying to copy this indicator to Excel. Do you mind getting in touch with me for a couple of questions, please? Cheers!
