Drawobjects sometimes not drawn

[FireFly]

Hi,

I'm working on an indicator that puts certain draw objects onto the chart, such as trendlines, diamonds, etc. I have noticed that when I scroll through a historical chart bar by bar, such that the indicator is updated on very bar, sometimes some of the drawobjects are not drawn at all! However, if I then "Reload Ninjascript" using the right mouse button, the indicator will draw all objects properly.

So it almost looks like my code is OK, but NT sometimes 'forgets' to draw some of the objects.
Do you know what is causing this? Am I overlooking something? And what can I do about it?

Thanks!

Hmm .. we are not aware of any bug related.

- please make sure you are on latest 6.5.1000.2
- if issue persists: please provide a simple as possible indicator where drawing objects just disappear by scrolling the chart back and forth

I'm using the lastest NT version (I already noticed the problem half a year ago in earlier versions).

The problem is that my code is currently almost 3000 lines that I don't want to disclose. It will be quite a lot of work to strip it down, while preserving the problem.

My reasoning has always been that my code is OK because all drawingobjects are OK when I press "Reload Ninjascript" when the problem occurs. Is this a fair assumption?

The problem is also not consistent: with the same data and same chart sometimes objects are drawn and sometimes not. However, after "Reload Ninjascript" I always get the same situation (= the situation I expect).

Btw: tried on 3 different PCs and CPU load seems low.

I see your point. However we would need a reproducible scenario in order to further analyze since we are not aware of any issue related.

I understand that. When I have time I'll see if I can strip the code while preserving the problem.

Anyway, it's not a high priority for me at this moment since I'm only using this indicator as an intermediate step to visualise the behaviour of parts of code that I'm writing for an automated strategy, so eventually I'm not going to need this indicator at all.
