Multi-Instrument CurrentBar Question

[freewind]

Hi,

I'm developing a multi-instrument strategy adding 9 more instruments.
Min bar is set to 20.

I have the following code :

protected override void OnBarUpdate()
        {
            if (BarsInProgress != 0) return;
            Print("CurrentBar =" + CurrentBar);
            Print("CurrentBars[0] =" + CurrentBars[0]);
            Print("CurrentBars[3] =" + CurrentBars[3]);
            Print("CurrentBars[8] =" + CurrentBars[8]);
            Print("CurrentBars[9] =" + CurrentBars[9]);
        }

The output I get is:

CurrentBar =335
CurrentBars[0] =335
CurrentBars[3] =335
CurrentBars[8] =335
CurrentBars[9] =21
CurrentBar =336
CurrentBars[0] =336
CurrentBars[3] =336
CurrentBars[8] =336
CurrentBars[9] =22
CurrentBar =337
CurrentBars[0] =337
CurrentBars[3] =337
CurrentBars[8] =337
CurrentBars[9] =23
CurrentBar =338
CurrentBars[0] =338
CurrentBars[3] =338
CurrentBars[8] =338
CurrentBars[9] =24
CurrentBar =339
CurrentBars[0] =339
CurrentBars[3] =339
CurrentBars[8] =339
CurrentBars[9] =25
CurrentBar =340
CurrentBars[0] =340
CurrentBars[3] =340
CurrentBars[8] =340
CurrentBars[9] =26
CurrentBar =341
CurrentBars[0] =341
CurrentBars[3] =341
CurrentBars[8] =341
CurrentBars[9] =27
CurrentBar =342
...

Can you explain to me this outcome?

TX,

What instrument / timeframes do you Add() here Roy? OBU() Processing would be started once all series have see the min bars required...

Thanks,

Do you mean that if 1 of the instruments have a less data all will wait for him to sync. with the other?
The instruments are few stocks, time frame is daily and the data I'm getting is from Kinetick Real-time service.

Correct Roy, first OnBarUpdate() call you would see is where all series have satisfied their min bars requirements.
