Using Plot data from Original Class Instance

[byi777]

Hello!


I would like to create few indicators (IndicatorA , IndicatorB, etc) based on Plot's data , calculated in one base Indicator and use all Indicators on the same chart.

Let's say for example that I would use MACD as my Base Indicator and use Avg values in IndicatorA.

I could use in IndicatorA formula MACD(12,26,9).Avg[0] to reach element 0 in DataSeries containing historical values for Plot Avg.
In IndicatorA I'll create PlotA.

In IndicatorB I will use formula to reach PlotA data as IndicatorA.PlotA[0].

In my understanding all these calls will create few instances of Classes defining MACD and IndicatorA and forcing system to use extra memory and processor power, recalculating the same values few times.

Do you have way to access data created by original Class Instance(MACD) used to plot actual MACD Indicator on chart?

Thanks

Unfortunately not. These will be separate instances.

Maybe there is some way to expose IDataSeries object representing The Plot globally?

Yuliy,

Unfortunately this is not supported. I suggest merging your calculations into one script if feasible for what you are trying to do and use multiple plots in the same script.

Josh,

In this case, could I place Plots from one script on few Panels.

Thanks

Unfortunately not. A single indicator can only populate a single panel. If you instead worked with a strategy, you could however use the StrategyPlot() technique to plot on multiple panels. This would consolidate all your calculations into one script which would not require multiple instances. http://www.ninjatrader.com/support/f...ead.php?t=6651

The latest approach sounds promissing.

Thank you, Josh!
