Is it possible (using ACSIL) to draw rectangles that occupy all of the bar space? I have tried stuff like: tool1.BeginDateTime = sc.BaseDateTimeIn[sc.Index] - (sc.SecondsPerBar * SECONDS)/2; tool1.EndDateTime = sc.BaseDateTimeIn[sc.Index] + (sc.SecondsPerBar * SECONDS)/2; Needless to say, it doesn't work. I'd appreciate any ideas on how to accomplish this. EDIT: I can't use "background color" for this as I will be drawing several different rectangles vertically (not shown in the attached image).

Happened to me when I built a numbers bars study. You can't use the rectangle tool since it draws from index to index or datetime to datetime, which always fall on the middle of a bar. The only workaround I found is to draw a vertical line and give it some width. Not the Vertical Line Tool.... just a simple line with a start and an end that make it vertical. There is still a problem that if you change the chart's bars spacing/width, your "bars" won't change width since they are of course hard coded to a fixed pixel width. If you do need it to follow changing bar spacing/width, its more complicated. you need to monitor the chart's spacing thru acsil, and give your bars a width option for every chart spacing (if-elseif-elseif-elseif etc). From memory I remember needing to do something like this (though with horizontal lines) since it wasn't as simple as finding a single factor to do "my bar width = chart spacing * factor". Good luck.

You cannot do this automatically, however you can use the Bar Top and Bar Bottom Draw Style pair and set the width in pixels to what you require.

Thanks Hendrixon, great idea. I never thought of drawing vertical line segments, that will do the trick. Together with the value of "sg.ChartBarSpacing" and "sg.SpaceBetweenChartBars" it should pretty much work automatically even if the bar width is changed. Sierra Chart Engineering - thanks, I'll look into that draw style, might be the same as drawing line segments if I understand it correctly. Date Time Of Last Edit: 2013-08-06 18:09:54
