How to Update a Line already drawn via a Strategy?

[ChainsawDR]

Hi,

Hoping you may be able to help please.

When certain criteria are met, I draw a dotted line to the Chart and store the Y value and CurrentBar for when the line begins into variables:

Draw.Line(this, "NewLine"+CurrentBar, false, 0, NewLineValue, (0-120),NewLineValue, Brushes.Blue, DashStyleHelper.Solid, 4);

In subsequent bars when certain conditions are met, I wish to "go back" and update the line to end sooner than the originally planned 120 bars. E.g. 15 bars later something happens, and I wish to cut the already added 120 bar line down to 15 bars.

Is it possible to update/edit a line that has already been drawn to the chart?

Many thanks in advance

Hello ChainsawDR,

Thanks for your post.

Yes, you can redraw the line with new parameters. To do so you would want to save the tag name of the line when it is created and then if/when you update later you can reuse the tag name and this will automatically remove the older line and replace it with the new line with the new properties.

Works a treat, thank you!
