Strategy adding MTF indicators to chart

[mr_trade]

Hi there,

I am trying to add a multi-time-frame indicator to my strategy to be displayed on the chart, but currently get display issues when adding the indicator.

I have the following code under State == State.DataLoaded

testRsi = RSI(BarsArray[1], 14, 3);
AddChartIndicator(testRsi);

When calling testRsi in the strategy logic, it is calling the correct data series and entries appear to be ok so know the above BarsArray[1] is working.
However the AddChartIndicator doesnt seem to reflect the new dataseries/BarsArray on the chart. Only half the RSI is shown historically and is clearly still calculating the RSI on the primary dataseries.

Am i missing a step here?

Thanks

Hello mr_trade,

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 to use AddDataSeries() you would not be able to supply BarsArray[1]. Instead, internally add the series with AddDataSeries() in the indicator and strategy.
Below is a link to an example.
