Draw.TextFixed will not compile in BarTypes in NT8

[Louis335]

Dear team,

Although the simple test line:

Draw.TextFixed(this, "tag1", "Test text", TextPosition.TopRight);

compiles fine in an Indicator type, it will not compile in a BarTypes type, even when using the same Using declarations.

The same line in a BarTypes gives the error:
CS1502 (the method has some invalid arguments)
CS1503 (indicating that the 'this' key word cannot be converted from NinjaTrader.NinjaScript.BarTypes.xBars to NinjaTrader.NinjaScript.NinjaScriptBase)

I cannot find anything in the NT8 manual on this.

Is there a work-around for this ?
And how can I find out which other methods may / may not work when compiled in different file types ?

Many Thanks

Welcome to the forums Louis365!

BarsTypes do not inherit from the NinjaScriptBase class like Indicators and Strategies do. As such, Drawing Tools cannot be used here.

BarsTypes are used only to build Bars objects and are not intended to place a visual indication on a chart. This would be best done using an indicator or creating your own custom ChartStyle which would be used with the custom BarsType.

ChartStyles use SharpDX rendering and would not use DrawingTools. If you are not familiar with SharpDX rendering, I suggest reviewing the Help Guide information below and following along the SampleCustomRender indicator that comes standard with NinjaTrader. NinjaTrader ChartStyles are also open source and can be referenced for examples. If the SharpDX rendering is too complex, you could build an indicator that uses Drawing Tools to accomplish your goal.

Please let me know if you have any questions.
