Rows in Output is not in the correct sequence

[aksamyo]

When I backtest my strategy against the DOW 30 folder, I print each bar that I receive. I expected the data to be printed in the output in the same sequence as the sequence of the instruments; however this is what I get:
2009-09-04T16:00:00 Instrument=AA BarsInProgress=1 Close[0]=12.18
2009-09-04T16:00:00 Instrument=BAC BarsInProgress=1 Close[0]=17.09
2009-09-08T16:00:00 Instrument=AA BarsInProgress=0 Close[0]=12.6
2009-09-08T16:00:00 Instrument=BAC BarsInProgress=0 Close[0]=17.02
2009-09-09T16:00:00 Instrument=BAC BarsInProgress=0 Close[0]=17.04
2009-09-09T16:00:00 Instrument=AA BarsInProgress=0 Close[0]=12.81

Shouldn't all "AA" be printed before all "BAC"?

Attached is the strategy.

No, since backtesting of a basket of instrument is multi-threaded with NT7. Multiple instruments are backtested at a time.
