AddDataSeries(string instrumentName, BarsPeriodType periodType, int period)

Can the instrument be updated programatically in Ninjascript?

Thanks!!

Hello GibbsB613,

Thanks for your post.

With reference to the helpguide: http://ninjatrader.com/support/helpG...dataseries.htm

The following is from the helpguide link above, I've italicised the relevant warning.

Warning:
• This method should ONLY be called from the OnStateChange() method during State.Configure
• Should your script be the host for other scripts that are creating indicators and series dependent resources in State.DataLoaded, please make sure that the host is doing the same AddDataSeries() calls as those hosted scripts would. For further reference, please also review the 2nd example below and the 'Adding additional Bars Objects to NinjaScript' section in Multi-Time Frame & Instruments
• Arguments supplied to AddDataSeries() should be hardcoded and NOT dependent on run-time variables which cannot be reliably obtained during State.Configure (e.g., Instrument, Bars, or user input). Attempting to add a data series dynamically is NOT guaranteed and therefore should be avoided. Trying to load bars dynamically may result into an error similar to: Unable to load bars series. Your NinjaScript may be trying to use an additional data series dynamically in an unsupported manner.
