I already feared that, considering that I remember that someone once asked for a Half trend AVGs. I looked for more than 30 minutes (until now) and I didn't find any repaint in this version (until now)

i don't think a non repaint half trend version has ever existed

I tried to make a smoothed volume weighted two pole (no smoothing) RSX of Ehler's Center of Gravity. OpenAI keeps telling me this code is the one.

But it does not

2. paint in the subwindow nor display data in the data window
1. complile correctly. it keeps using input in the 2 pole calculation

Never seen a volume weighted two pole ma, can possibly do a cog pre-smoothed with super smoother (think that would be the 2 pole) then make an rsx from that, but being rsx is already pretty smooth normally not sure how adding pre-smoothing to the cog would cause more lag.

sounds good, and dont forget the volume weighted part :P
