Oddball test data

["Dennis Todd" <dtodd@xxxxxxxxx>]

I pulled down data from www.trades2traders.com for the NYSE advancing and
the S&P one minute data a while back.

The NYSE advancing issues data, most of it had times of about 33-35 minutes
past the hour. When I test this with the standard oddball code and use the
S&P I get really bad results. Is this a result of having the NYSE advancing
issues offset by ~30 minutes? If so, is there better data somewhere for the
NYSE advancing issues that is on the hour? Or am I doing something wrong in
my testing?

Thanks in advance!
