el question day of week statement

["Sentinel Trading" <rjbiiilis@xxxxxxxxxxxxx>]

I added the following statement to a system while trying to include the weekly
avg for daily data into a system to insure a trend in two time frames, It
increased the number of trades and greatly improved the returns on the SP 500
daily. The statement IF DAYOFWEEK(DATE) < DAYOFWEEK(DATE[1]) THEN BEGIN when
removed decreases returns with several stopped trades. Any insight would be
appreciated. I'm posting the whole system not the returns, I'd be interested in
knowing anyone else tries backtesting it. If anyone requests I'll send the ELA.
Thanks for any insight.
