Trying to make this ind mtf with no success

I have the suspicion that the error is at limit var and the way it is calculated ,
because the way it is currently coded is referring to the current timeframe and doesn't take into account the selected timeframe...

Thank you so much mladen for the fast response to my request and the extra addition of the interpolation,
i got it all wrong from the beginning as i can see now.

Is there a way to mark the topic as <RESOLVED>?I cant find a way to edit the title and add the "tag" there

Edit: OK found it and added the "tag" at the title
