How to check for Time being valid?

[ETFVoyageur]

How should I check to see whether Time is valid before trying to access it?

• Time is often non-null, but still invalid, so that does not work
• Time.Count throws if accessed before Time is valid. Technically one could do a try...catch, but that is not really a very satisfactory method
• I know from the debugger that Time is sometimes valid and sometimes NULL when State >=State.Historical. I do not like a state-based method anyway, because it is subject to breaking in the future if the implementation changes
• ISeries supports IsValidDataPoint(0), but unfortunately TimeSeries does not

What I am really looking for is a way to directly test whether or not Time is yet valid. Any suggestions will be appreciated.

Thanks,

If you're talking about the TimeSeries associated with data bars, as long as CurrentBar != -1, the value of the Time[0] should be set.

if(CurrentBar != -1)
     Print(Time[0]);

Time of "what"? And how do you mean "valid"? What is the determinant of validity? A time is a time.
