Calling another indicator - data series

[NinjaCustomer]

What data series does it use when you call another indicator?

The same one as the chart?

How can you specify specifically another - say, you want to call another indicator on 200 ticks when the main indicator is on a 5 minute chart ?

and is this code correct indicator.Value.GetValueAt(CurrentBar) to get the latest value?

Hello NinjaCustomer,
Thanks for your post.

What data series does it use when you call another indicator?

You are correct. Unless you specify for a different series to be used as the input then you will use the primary data series when calling an indicator. You are also correct that you could use that code for that purpose. For example, both of the following prints will produce the same value.

Print(SMA(20).Value.GetValueAt(CurrentBar));
Print(SMA(20)[0]);

How can you specify specifically another - say, you want to call another indicator on 200 ticks when the main indicator is on a 5 minute chart ?

Something similar to the following snippet would add a 200 tick series, and then use that 200 tick series as an input to the SMA using BarsArray.

protected override void OnStateChange()
{
	else if (State == State.Configure)
	{
		AddDataSeries(BarsPeriodType.Tick,200);
	}
}
protected override void OnBarUpdate()
{
	Print("The Primary Data Series' SMA(20) = "+SMA(BarsArray[0],20)[0]); 
        Print("My 200 Tick SMA(20) = "+SMA(BarsArray[1],20)[0]);
}
