Bar Index needs to be greater/equal 0

[habibalex]

I'm getting an ArgumentException in a multi-timeframe indicator. I don't quite understand why this would be an issue since I am calling the Count property of the timeseries to find the end of the array. It should correspond to the number of BarsAgo and return the 1st DateTime in chart.

Times[1][Times[1].Count - 1]
=> 'Times[1][Times[1].Count - 1]' threw an exception of type 'System.ArgumentException' System.DateTime {System.ArgumentException}

Times[1][Times[1].Count - 7]
=> {3/3/2015 3:00:00 PM} System.DateTime

I'm calling this code in this if statement:
if(Historical && BarsInProgress == 1 && Times[1].Count - 2 == CurrentBar){

}

Why is it Times[1].Count - 7, instead of Times[1].Count - 1?

habibalex, you mean rather why it would be the Count - 1 with the exception instead of the Count -7? What series are you dealing with here and how would the be loaded from the data series window? Do you load based on days back? Is it the same outcome for other instruments, so we could rule out potential cache issues for this market?

On which series do you run the returned index? Would this be a custom series that may potentially not be synched to the added series but as default for the primary?

Yes I am getting an exception with Times[1].Count - 1.
I add a dataseries in the initialize function, I get the error w/ both 6E and ES:
Add(PeriodType.Tick,1);

Habibalex,

Would you be willing to attach your script or a toy script that reproduces this so I can review and investigate this.

[habibalex]
