Plotting 5 minute EMAs on 1 minute chart not working

[jaybedreamin]

Hi there,

I am trying to accomplish something very simple in NinjaScript. I'm simply trying to calculate two 5 minute EMAs and have them plotted on a 1 minute chart. For some reason, only the 1minute versions of the indicators are showing. The strategy only runs on a 1 minute chart, but I need the 5 minute ema values plotted.

Any idea what I'm doing wrong?

Hello jaybedreamin,

From the help guide:
"An indicator being added via AddChartIndicator() cannot use any additional data series hosted by the calling strategy, but can only use the strategy's primary data series. If you wish to use a different data series for the indicator's input, you can add the series in the indicator itself and explicitly reference it in the indicator code (please make sure though the hosting strategy has the same AddDataSeries() call included as well)"

https://ninjatrader.com/support/helpGuides/nt8/addchartindicator.htm

This means the indicator needs to add the series and plot the values on the primary series.

Every bar needs a plot value set to see the plot. If there is no value to set on the lower time frame, set the value to the previous bars value.

Below is a link to an example of plotting a higher time frame on a lower time frame.
