Ray vs IRay

[chartish]

I am trying to convert a NT7 inidcator to NT8 and I ran into these lines of code:

IRay downTrendRay = (IRay) DrawObjects["DownTrendRay"];
startBarPrice = downTrendRay.Anchor1Y;
endBarPrice = downTrendRay.Anchor2Y;;
downTrendStartBarsAgo = downTrendRay.Anchor1BarsAgo;
downTrendEndBarsAgo = downTrendRay.Anchor2BarsAgo;


How do I get the anchor values from Ray in NT8?

Hello chartish,

Thanks for your post.

NinjaTrader 8 Ray anchor values can be retrieved using the StartAnchor and EndAnchor properties of the Ray object.

For example:

Ray myRay = Draw.Ray(this, "tag1", 10, 1000, 0, 1001, Brushes.LimeGreen);
	Print(myRay.StartAnchor.Price);

I'll provide documentation links for Ray's and the IDrawingTool interface which also explains how ChartAnchors can be used. Also helpful while converting NT7 indicators would be to reference the Code Breaking changes page of the Help Guide which provides a quick reference for NinjaTrader 7 items that have changed in NinjaTrader 8.
