Code to extend manually drawn rectangles

[coolmoss]

Below is the code I'm using to extend manually drawn rectangles to the current bar. I pulled this code out of another indicator that extends rectangles programmatically drawn and that indicator works fine. The code below does not extend, but it does compile. I realize there is no check for user drawn, but I'm not concerned about that. Also, I checked that my rectangles are not locked. Any ideas where I'm going wrong?

protected override void OnBarUpdate()
        {
            if (CurrentBar < 1)
				return;
			
            foreach (IRectangle draw in DrawObjects)
			{
					IRectangle Extend = (IRectangle) draw;
					Extend.EndBarsAgo = 0;
                         }

Hi coolmoss,

Thanks for your post.

Our development department is aware there is a bug as of release 15 that causes this to not work correctly.

You mention that the indicator is still working.

Which indicator did get this code from?

Hi Chelsea,

Yes, I'm still running release 15. Does 16 resolve this?

The code is a stripped down version of something in another proprietary indicator of mine. If it would be helpful, let me know how to send it to you via email. I just checked and the original indicator is extending the rectangles correctly.

Thanks for your help on this.

Hi coolmoss,

It has not been corrected in release 16.

If you can, please send the script to support[at]ninjatrader[dot]com.

In the body of the email please write Attn: Chelsea #936463. Also include a link to the forum thread.

Hi coolmoss,

I have responded to you via our email, but for anyone else reading this thread, the issue exists with manually drawn objects but not objects that are drawn from a script.

[coolmoss]

Is there any timeline on when a fix for working with manually drawn rectangles might be forthcoming?

Hi coolmoss,

I cannot give an ETA on when bug fixes or feature requests will be implimented.

Currently our development team is working hard on completing Ninjatrader 8. However, I do know they are continuing to address bugs in NinjaTrader 7.

I can, however, update you in this thread when we receive news this bug has been fixed.

Chelsea,

Finding a workaround to this would is a priority for me, so, what do you think about trying the following:

Have the script check for the manually drawn rectangles, create new rectangles programmatically which are identical to the manually drawn rectangles, then have the script extend the programmatically created ones.

I realize this isn't terribly elegant, but it might work. Based on your knowledge of the current bug/limitation, is this worth trying? Thanks for your help.

I was about to post such an idea... but I'm not about to find out programming it on my own time.

Look up NT_Ryan's code for alert for manually drawn lines... in the file section... if you can hack that to extend a line...you will be on to something.

Thanks Sledge. Unfortunately that is the code I was using, more or less. It appears the issue is specific to rectangles.

Hey coolmoss,

Thats a neat idea.. I'll have to do some testing to see if we can get that to work.

I'll let you know what I find.

Hi Coolmoss,

The issue seems to be the same. While I can get a start bar and end bar and then draw a new rectangle, I cannot remove the manually drawn rectangle with RemoveDrawObject. Again this only is working for objects that are drawn with the script and not drawn manually.
