AddHeikenAshi() to change with timeframe switch

[gyilaoliver]

Hi,

I would like to add Heiken Ashi into my indicator as secondary data series.

The function and the syntax is clear, however my question would be : what syntax should I use so that whenever I change the instrument or the timeframe, the Heiken Ashi data series would follow my primary settings? In the code below, I add a 1 minute Heiken Ashi, but if I would like to switch to 15 seconds bars, I would like Heiken Ashi to switch as well. Or if I change the instrument to NQ, Heiken Ashi should also follow that.

Thank you

  {
      Name = "Examples Indicator";            
  }
  else if (State == State.Configure)
  {
        AddHeikenAshi("ES 12-24", BarsPeriodType.Minute, 1, MarketDataType.Last);
  }
}​

Hello gyilaoliver,

Thank you for your inquiry.

AddHeikenAshi is not supported to be used dynamically in this way.

"Arguments supplied to AddHeikenAshi() 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 in 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."

Any HeikenAshi series you want to use in your script must be hard-coded.
