NT7: Plotting Multiple EMA from Different Range Barss

[Jim-Boulder]

In NT 7 I have a chart whose primary series is a 13Range bar, I want to plot the 13-bar EMA from the 4,13,21,and 34 Range bars---on this chart, I do NOT need the 4,21,34 range bars to plot--just the 13-bar EMA from them.

I have added the EMA's by adding these other series to the charts 'data series' definition, however, it is distorting the visual display the primary chart.

Is there a way to NOT plot the other series bars other than the primary?

Ultimately I want a single bar chart (13 Range Bar)--with 4 EMA lines--all a 13Bar EMA plot from the 4,13,21,and 34 Range bars.

I don't think I can ratio the EMA's like I could in a time chart (like a 13 minute chart)--because the bars don't form in sync with each other.

Hello Jim- Boulder,

You can do this with custom programming a multiseries indicator. Series are added for calculation purposes, but not plotted.

A sample multiseries script is available by clicking tools > edit NinjaScript > Strategy > Sample MultiTime frame. Documentation is available here:

http://www.ninjatrader.com/support/helpGuides/nt7/multi_time_frame__instruments.htm

Add the series in the indicators Initialize() method. You can then pass BarsArray[ ] into the EMA. 0 = Primary Series, 1 = Secondary Series, 2 = Third series, etc.

Value.Set(EMA(BarsArray[1], 13)[0]); //Plots the second series EMA (first added series)

thanks-how would I add an additional PLOT line to plot the EMA of dataseries index 3 for instance...I am having issues adding multiple Plot lines inside (one for each dataseries) of the strategy....

If this is in a strategy, you first add statements in the Initialize method. These are just placeholders for the actual values that are set in OnBarUpdate. This sample can help with strategy plotting:
