Not really sure how close to the TradingView versions these are, but made a Follow the line and an angle of follow the line, seems to work ok, just not sure how close to the originals these are.

I would like to suggest the MTF function in this indicator and the inclusion of new averages if possible, it has a similar behavior to the half trend

Maybe I posted twice, in which case I apologize in advance...

thank you very much!!
