I would like to suggest esignal add a new efs function to return the chart window width and hight. Because drawtextpixel only positions objects relative to left border of the chart window, it is hard to arrange objects to the right side of chart window nicely unless passing chart width in pixels as an efs parameter. However in such way, whenever a chart size is changed, the user has to edit the study to update screen width. So unless it is possible to arrange objects "relativetoright", exposeing chart window size to efs would be a very helpful improvement.
