Cannot Reference to the Ask Data

[cecshab]

I am able to download the ask bid data from esignal.
I can plot them in the chart (see the screen shot green is ask, red is bid, black is last)
But when I reference my ask data in my indicator,
Add(Instrument.FullName, PeriodType.Tick,1,MarketDataType.Ask);

and

Plot0.Set(Closes[1][0]);

I can't see it. (see the second screenshot)

but if I plot the trade data:

Plot0.Set(Closes[0][0]);

I can see it ( see the first screenshot)

so the problem is Closes[1][0] and Closes[0][0]

Is it a bug?

Update:
I changed the code to plot the "last" type instead of "ask" type. :
Add(Instrument.FullName, PeriodType.Tick,1,MarketDataType.Last);
All indicator value still zero. It seems it is not the problem of ask type but the problem of closes[1] not working.

Any errors you would see in your Control Center log tab?

Do you have a CurrentBars check for all involved / ADDed series running at the OnBarUpdate() start?

Thanks

U r right! Thx for telling me about that, I am new to ninja trader. Your answer help me alot!!!

After I added this line of code, everything works like a charm
if (CurrentBars[0] < 0 || CurrentBars[1] < 0 || CurrentBars[2] <0){
return;
}
