A hosted indicator tried to load additional data - AddIndicator to chart

[ricardo88]

Hi,

I'm having an Error message "A hosted indicator tried to load additional data" when I add OrderFlowCumulativeDelta Indicator to strategy; How do I fix it?

The code is as follows:

if (State == State.DataLoaded)
			{
				AddChartIndicator(OrderFlowCumulativeDelta(CumulativeDeltaType.BidAsk,CumulativeDeltaPeriod.Session,0));
			}

protected override void OnBarUpdate()
		{
			if(CurrentBar <= 100) return;
		}

Attached is the full code.

Thanks in advance.

Hello ricardo88,

Thank you for your note.

Because the OrderFlowCumulativeDelta adds a secondary tick series, your strategy would need to add this as well.

You would have the following code in your strategy,

else if (State == State.Configure)
{

AddDataSeries("ES 06-18", BarsPeriodType.Tick, 1);

}
if (State == State.DataLoaded)
{

AddChartIndicator(OrderFlowCumulativeDelta(CumulativeDeltaType.UpDownTick,CumulativeDeltaPeriod.Bar,0));

}

Please let us know if you need further assistance.

Thanks for the reply AlanP, it worked as expected

I'm trying to make AddDataSeries dynamic, I mean, OrderFlowCumulativeDelta load the instrument that I've selected in the chart instead of always loading the same instrument ("ES 06-18" with 610 tick bar).

I'm trying with the next code but with no chance. I got the same Error: "A hosted indicator tried to load additional data..."

else if (State == State.Configure)
			{
				instrumento = this.Instrument.FullName.ToString();
				periodo = BarsPeriods[0].Value;
				AddDataSeries(instrumento,BarsPeriodType.Tick,periodo);
			}

Attached the full code. Thanks in advance.
