Yes it worked, thanks a lot Mrtools.
btw, what is color red for? the one with "color late" buffer?


Also, was wondering if for MT4 already exist ot its possible to make something like this indicator from tradingview that calculates angles of bollinger bands:

this is the explanation of the indicator:
"This script is used to calculate angle of Bollinger Bands and also setup alerts.

The angle is based on the rules:

- if the previous 2 is 1.1, previous 1 is 1, and the current is 1.1, then the angle should be 90 degrees.
- if the previous 2 is 0.9, previous 1 is 1, and the current is 0.9, then the angle should be 270 degrees

If upper angle is below 90 degrees and close is above the average, it is long signal.
If lower angle is above 270 degrees and close is below the average, it is short signal.

- It is good for catch trend trading.
- Not good for swing trading as the BB changes are very tiny but angles for upper may hit below 90 degrees or angle of lower may be above 270 degrees.

hello mrtools

may You add arrows when lines crosses the other .
Of course it is, but sometimes it doesn't work.
And add some options to it.
thank you

It repaints, it's the same as step stochastic, there are some non-repainting versions posted in the forum.

mrtools wrote: Tue Apr 16, 2024 3:26 am Are you aware that that version can repaint.

Mrtools thanks for the answer.
I was thinking of using it as a semaphore, for a complex signal
In the system that I want to make for NINA the main role is not assigned,
it roughly looks like this.
Redrawing is not too scary, I have a fairly reliable filter for it.

Thank you.

No interest to my request??

Looks interesting enough

Sorta wasn't an interesting request because no chart image or simple explanation to what this indicator is.... so what benefit will it give to other traders

mrtools, kvak, and the master coders here, I was wondering if it would be possible to have this indicator ported for MT4.

FYI, I'm working on it but it's still not finished….

Looks good! Can't wait to see the final product.
