graphics within custom bartypes

[soulfx]

Hello, i am working on a couple of custom bar types - one of them i considered it useful to display a text marker or arrow on the chart as the bar evolves which conveys which state the bar is in.

I tried to use the Draw.ArrowUp method and needed to add the required 'using' declarations and receiving error Argument 1 : cannot convert from Ninjatrader.NinjaScript.BarsTypes.xxx' to NinjaTrader.NinjaScript.NinjaScriptBase

Obviously the key difference for a an indicator at the top is it is derived from Indicator and references the NinaTrader.NinjaScript.NinjaScriptBase
whereas a bartype derives from BarsType and reference Bartypes names space.

Is it possible to derive from both to achieve the drawing effect here -

For the most part graphics are handled separately in indicator methods and overlayed onto the bars on the chart but wondered if i could generate some graphics within the bartype code itself. This may not be possible or advisable and am seeking some confirmation on this

thanks

Hello soulfx,

No, drawing objects are not available to bar types. Drawing objects can be called from Indicators and Strategies.

For any custom drawing, you can do this in a ChartStyle in the PaintBars override using the graphics library (GDI+).

This would be an undocumented approach and resources are few, however, below is a link with some information about custom drawing in a ChartStyle.

However, from your description, it would seem that you could achieve your goals using an indicator that works with this bar type, allowing you to use NinjaScript drawing objects.
