simon_n3z wrote: Sun Nov 19, 2023 8:20 pm 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

Code: Select all

and finally i wanted it done in my way of the formula, im not sure what the ai did....

WHAT IS MY MAJOR MALFUNCTION ?

Plz help a brother out *nudge nudge *

Thank you in advance

mrtools wrote: Mon Nov 20, 2023 10:31 am 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.
