Calling SMA and EMA while interfacing Gui.NinjaScript.MarketAnalyzerColumnRenderBase

[karlomacariola]

Hello, I hope someone can help me with this which I am trying to figure out for some time now. I'll be grateful if someone can point me to the right direction.

I am writing a custom Market Analyzer Column script and I want to customize the column's color depending on its value so in my script, I am interfacing Gui.NinjaScript.MarketAnalyzerColumnRenderBase instead of the default MarketAnalyzerColumn to make color customizations in OnRender(). The problem is when I switch to this interface, I lose access to indicator functions like SMA, EMA and other built-in NinjaTrader functions in the body of my script particularly in OnBarUpdate().

My question is: is there a way to access SMA(), EMA() and other NinjaTrader indicator functions while interfacing Gui.NinjaScript.MarketAnalyzerColumnRenderBase in a Market Analyzer Column? Many thanks in advance to whoever can help.

Hello karlomacariola,

I would suggest looking at the ChartNetChange column for some examples of how to access data when using OnRender in a column.

You can still access all the same series or indicators but you need to change how you access their data. To access bar data you need to access the GetClose/Open/High/Low methods and supply an index, BarsAgo does not work in OnRender. The same concept applies to indicators you would need to use GetValueAt when accessing indicator values from OnRender.

One other note is that you will also need IsDataSeriesRequired = true; in State.SetDefaults which is shown in ChartNetChange also.
