FirstTickOfBar not trigger

[asafs]

Hi,

I am developing an Indicator that uses few Instrument as follows:
protected override void Initialize()
{

Add("$EURUSD",PeriodType.Minute,15,MarketDataType. Last);
Add("ES 09-13",PeriodType.Minute,15,MarketDataType.Last);
Add("QM 10-13",PeriodType.Minute,15,MarketDataType.Last);
Add("GC 12-13",PeriodType.Minute,15,MarketDataType.Last);
}

FirstTickOfBar is not trigger for some of them for example: QM although I can see the bar changes in the graph the FirstTickOfBar is not triggered.
any idea how to solve this issue?

Thanks for the post asafs, how do you determine that exactly via the code? Do you a print on the FirstTickOfBar per BarsInProgress?

Would you see this as well if you used this changed Add?

protected override void Initialize()
{

Add("$EURUSD",PeriodType.Minute,15);
Add("ES 09-13",PeriodType.Minute,15);
Add("QM 10-13",PeriodType.Minute,15);
Add("GC 12-13",PeriodType.Minute,15);
}
