If your swing points are defined, you do not need a loop.
Try this:
BarsSincePoint_A = BarsSince(SwingPoint_A);
etc

Subject: [amibroker] a loop need to count bars
> Hello .. Headache with High and Low Swing Point Triangles
> I need a help for a loop
> Every time that we have a Swing Point I would like to draw a line to the
> left until the line to find a price bar.
> Then we have to count how many lower low we have on the left side of the
> triangle and how many higher high of the right side.
> And when the left side of the triangle the bars are less than the left
> side I would like to draw a triangle like this in the picture that I
> attach
>
> Do I need to write a loop to count that bars?
> If the left bars are less than the right side the triangle is correct
