Is there any way to optimize my use of the draw tool? I am in a situation where I am using thousands of DRAW_HORIZONTALBAR's at a time, and I am already using the basic optimizations like setting sc.FreeDLL=0, manual looping, and using s_UseTool.BeginIndex|EndIndex. |

These really are the only optimizations there are when using the drawing tools from ACSIL: sc.FreeDLL=0, manual looping, and using s_UseTool.BeginIndex|EndIndex
What especially makes the most difference is using BeginIndex and EndIndex. We need to understand the problem better. When you scroll the chart, do you notice that it is like sluggish?

Yes, very slow. Several second delay between grabbing and moving the mouse, and the chart responding.

Yes, the more lines on-screen, the greater the lag.

To confirm, you are only using BeginIndex and EndIndex and not specifying the position of a drawing using SCDateTime BeginDateTime SCDateTime EndDateTime? If you are specifying the position using indexes, and you still notice a sluggishness, then you just have too many drawings of a chart and have to reduce them. There really is no other possibility. You cannot go to an extreme. Sierra Chart Support - Engineering Level Your definitive source for support. Other responses are from users. Try to keep your questions brief and to the point.

I realize this method of identification will cause extreme sluggishness. Are you aware of ways to optimize the specification of drawing objects relative to the y-axis? |

You should only add a small number of drawings at a time. Remove drawings that are not visible. This is what we recommend.
