Oddball Question

["Dion Kurczek" <dionkk@xxxxxxxxxxxxxx>]

I'm experimenting with the Oddball system and I have a quick question about
the trade by trade data:

http://www.oddballsystems.com/positions/X.SPX-S0007.txt

Does each entry in this file represent a single bar of data?  I see that
some days end at 3:00 PM while most days have an additional bar of data,
3:15 PM.  Since Oddball is based on the 7 bar ROC it seems that the extra
(eighth) bar would throw off the results.

Am I right to assume that a testing dataset should contain 7 hourly bars per
day, 9:00 AM through 3:00 PM?

Thanks much!
