RemoveDrawObject

[anmir55]

I have a first "if" that according to a bar closure draws me some pictures. Then I have another "if" independent of this with other conditions. I have added this sequence to erase these two squares that have been generated before and when some conditions are not met, but now to load a chart that has two historical days and that used to take 1 minute now takes 15 minutes ... there are some option to make it faster?

if ( DrawObjects["PR" + (CurrentBar-1)] == null && DrawObjects["PH" + (CurrentBar-2)] != null && DrawObjects["PH" + (CurrentBar-3)] != null)
{
RemoveDrawObject("PH" + (CurrentBar-2));
RemoveDrawObject("PH" + (CurrentBar-3));
}

Hello anmir55,

Thanks for your post.

There will be an expected delay when using RemoveDrawObject which can be exacerbated when called multiple times during historical processing. Heavy use of Drawing objects is also prone to performance issues. I may suggest using SharpDX rendering instead to improve performance.

I have attached an example that can be used for demonstration. Custom rendering routines would be needed for other kinds of drawings.

For an introductory look at using SharpDX, I recommend viewing our SampleCustomRender indicator and the documentation below.
