NT7B5 - DataSeries in Multi-Instrument Strategy Error

[bethewater]

Hi,

I'm using the following strategy code on a ES 12-09 (Zen-Fire) chart, and get the following output:

CurrentBar: 37
**NT** Error on calling 'OnBarUpdate' method for strategy 'TestDSStrategy/307ee535ba044c06b4ae971d5128ceac': Index was outside the bounds of the array.

When I comment out the "Add("TF 12-09", ..." line, I get no error with the following output:

CurrentBar: 20
testDS[0]: 1104.5
CurrentBar: 21
testDS[0]: 1104.75
...

Note: I am using all the default Strategy settings when attaching to the chart of ES 12-09.

Thanks

public class TestDSStrategy : Strategy

private DataSeries testDS;

}

protected override void OnBarUpdate()

if ( BarsInProgress != 0 ) return;
testDS.Set(Closes[0][0]);

Print("CurrentBar: " + CurrentBar);
Print("testDS[0]: " + testDS[0]);

Forgot to mention, I'm using: 1 min - Ask (on the chart).
