I still have an unanswered question.
why???
Why does this thing work, why?
I've already broken my head.
I can't get the formula to the end, from which this dependence will be clearly visible.
I have an outstanding question

It's a real pain in the arse.

all of it, all of it
All right, I got it.
I'm waiting for the results from the others now.all of them, all of them.

Have you seen what a late-model Cadillac looks like? I should have one.
Roman, I've been using mathcad to do the math.
How are you gonna do it?
Roman, for example, I've been using mathcad to do the math.
What are you gonna do?
I did it a long time ago.)

Hall Help #2
There are two lines (MAs) with the same period :
* red - regular LWMA
* orange - sin-weighted, calculated on log prices (https://www.mql5.com/ru/forum/448777/page167#comment_50811587).
Question: why the heck do they match ? (like any average, they should be close, but not that close).
as an option, maybe I lost accuracy somewhere (in log. they are small and close values), and got special effects double
I think it's like this:
then give me some ideas and methods - how to do calculations with log (with close values), avoiding such pitfalls.

why so difficult to calculate?
exponent from the sum of logarithms is the product of
MathExp(sum(MathLog(x[i]*W[i]))) = prod(x[i]*W[i]))

subtract one from the other, metac catches tiny numbers, output the result in the basement.
Isn't digits hanging on indik by any chance?
