    Operator '*' cannot be applied to NinjaTrader.Indicator.StdDev

    Hi,

    when trying to add the following rule to a strategy

    CrossAbove(ROC(KAMA(Low, 2, 20, 30), 5), 0.25*StdDev(ROC(KAMA(Low, 2, 20, 30), 5), 100), 10) == false)

    I get the error message:

    Operator '*' cannot be applied to operands of type 'double' and 'NinjaTrader.Indicator.StdDev'

    how can I overcome this? I need to have a fraction of the Standard Deviation, how can I multiply the output of the StdDev with a percentage?

    many thanks
    Paulo
