    Thanks. That is consistent with the behavior I have observed.

    Hello ntbone,

    Yes, NinjaTrader caches the series objects and does not technically duplicate them. However, the indexes remain, and OnBarUpdate will still run for both of the duplicated series.

    That's not what I was querying, nor what my conculsion was.

    If I have a 1 minute chart, and I have a call to AddDataSeries(BarsPeriodType.Minute, 1); the BarsArray[0] will be the exact same object as BarsArray[i] for the index which correlates to AddDataSeries call. It doesn't appear to generate a separate object but puts the reference to the same object in both slots of the BarsArray[].


    I would also expect, if for some odd reason, I called AddDataSeries(BarsPeriodType.Minute, 1) twice in a row, that the object in the BarsArray[] for both series would be the same object.

    Hello ntbone,

    It is expected that there will be a BarsInProgress and BarsArray index for the primary series and for each series added with AddDataSeries.

    I checked for BarsArray[] equality and sure enough BarsArray[0] == BarsArray[i] if the data series for BarsArray[i] is the same time period as the chart.

    Multi-Series Indicators and Duplicate AddDataSeries

    If I am looking at a one minute chart and my indicator has code to AddDataSeries(BarsPeriodType.Minute, 1) I will have two bar series in the chart that are covering the exact same time period. Is the data duplicated?
