Adding multi-timeframe dataseries - no data loaded

[dontpanic]

Hi,

this has been an ongoing issue for me for some time, and I have posted about it previously.

My indicator is fairly simply, its just for displaying 5 minute volume data on my range chart. I have narrowed the error down to the condition that BarsArray[1].Count=0.

I use the following function inside Initialize()

Add(PeriodType.Minute, 5);

So now, before attempting to access the volume I have to check the size of the additional data series. At certain times, intermittently, I get BarsArray[1].Count=0. I have not been able to determine exactly what conditions cause this state, but it is possibly related to time of day. When this condition arose again just now (its been in this state for about an hour, on more than 1 different instrument) I reloaded all historical data and reloaded all ninjascript with no change. I restarted NT and then the data appeared. But I have restarted NT several times this morning and it hasn't fixed the problem.

Can someone help me to track down the cause of this issue?

thanks,
will.

Edit : one other thing that I noticed was that OBU was not called for BarsArray[1] when the chart was reloaded.

Hi dontpanic,

Try using Add(Instrument.FullName, PeriodType.Minute, 5);

Does this correct the issue?

Where are you printing BarsArray[1].Count? (Don't do this in Initialize(), do this anywhere else though)

What is the interval/bar type of the primary series?

Hi Chelsea,

so far that change has made a difference but I will check over the next few days to see if the errors return.

Why does that make a difference?

Thanks,
Will.

Hi dontpanic,

Add with an instrument requires 3 overload parameters.

Hi chelsea,

my question was more to understand WHY the extra parameter makes a difference. If you dont call with that parameter, what is the difference?

Hi Will,

I see your point. Two overload parameters should be correct and should return the primary instrument.

What are the differences you are seeing?

Hi Chelsea,

can I forward you some further information including a log and my indicator source via email? I'm still having problems and unable to identify what is happening.

Thanks,
Will
