Subject: [amibroker] GFX x y position conversion question
> Does anyone know if there is a way to convert the X and Y coordinates from
> the price chart directly to X and Y pixel coordinates?
> I simply want to draw polygon shapes of chart patterns. Since I already
> have the pivots and lines on my current chart I simply want to do a color
> fill. I don't want to have to do loops to recreate everything that I
> already have.
>
> Any help is appreciated.
>
> I will post the completed project if I can find a way of doing this.
