    Sum function error ninjascript series

    I am trying to create a variable that sums N periods of the OrderFlowCumulativeDelta.

    but when I try to create a variable(value) using the SUM function
    double value = SUM(cumulativeDelta.DeltaClose[0], 2)[0];

    I get the error "cannot convert from 'double' to NinjaTrader.NinjaScript.ISeries<double>"



    I can use simple logic under OnBarUpdate() like
    (cumulativeDelta.DeltaClose[0] + (cumulativeDelta.DeltaClose[1] >0)

    I can also set a variable (value)
    double value = cumulativeDelta.DeltaClose[0]+cumulativeDelta.DeltaClose[1];



    I was able to create a variable "cumualtiveDelta" accessing NT8 OrderFlowCumulativeDelta ** with help from the forum and help guide

    namespace NinjaTrader.NinjaScript.Strategies
    {
    public class TestCumDelta : Strategy
    {
    private OrderFlowCumulativeDelta cumulativeDelta;
    }


    I


    Any help with the proper syntax to assign the SUM function to a variable would be appreciated

    Hello sdauteuil,

    cumulativeDelta.DeltaClose is a series of doubles (Series<double>).
    https://ninjatrader.com/support/help...ive_delta2.htm

    cumulativeDelta.DeltaClose[0] uses an index to select the most recent double in this series.

    Perhaps remove the index '[0]' to return the series and not the most recent bar's double value?
