Draw.TextFixed() in Drawing Tool Script Throws an Exception

[ramckay]

I am modifying a script for the drawing tool RiskReward that was posted on the forum. The modification displays the number of shares needed to satisfy the risk selected by the drawing tool. That works correctly. To more readily view the drawing tool text I want to to display the calculated number on the chart. I used Draw.TextFixed() to do this.

Draw.TextFixed(this, "tag1", "Text to draw", TextPosition.TopRight);

This line of code causes an exception:
class NinjaTrader.NinjaScript.DrawingTools.RiskRewardAB3
Represents an interface that exposes information regarding a Risk Reward IDrawingTool.

CS1503:Argument 1: cannot convert from 'NinjaTrader.NinjaScript.DrawingTools.RiskRewardAB 3' to 'NinjaScript.NinjaScript.NinjaScriptBase'
Any suggestions?

Thanks

Hello ramckay,

Thank you for your post.

Unfortunately, Draw objects can only be called from indicators or strategies.

If you would like to achieve the same effect as calling Draw.TextFixed(), I recommend taking a look at the code in OnRender() for Draw.TextFixed (within the Text DrawingTools script).

You could extract the OnRender code for Draw.TextFixed and reuse it to draw text in the same way.

Please let us know if you have any further questions.
