Remove all line or all arrow up from chart

[wokitun]

Hi guys!

Please help me if its possible.

I'd like to /from an indicator/ remove all special draw type from chart.

For example
RemoveDrawObject (all Hline)
or
RemoveDrawObject (all arrow up markers)

I don't know and I don't care the tags name...

So without tags, how can i do this?

Thanks for advance

I would try something like this. I haven't tested this but it should work.

foreach (IDrawObject draw in DrawObjects)
 {
         if (draw is ILine)
         {
                 Print("Line Object: " + draw.Tag);
                 RemoveDrawObject(draw.Tag);
         }
 }

Instead of ILine you would use the drawing object you wish to remove

Let me know if I can further assist.

Hi Lance!

Thanks for your reply.

Unfortunately is not working.
If I draw manually a line on chart... I see the tag name in output window, but not removed...
Can i remove it from an indicator?

wokitun, would unfortunately only work for lines drawn from the script. This is done purposely so malicious code could not influence other user / manual drawn objects.
