[R-SIG-Finance] quanstrat rule to exit same day close (using daily data)

[algotr8der]

I am trying to backtest a strategy that requires an exit on the close (same
day as the entry).  I have searched through Rmetrics and stackoverflow and
found the following post:

http://stackoverflow.com/questions/10441614/quantstrat-in-r-setting-a-date-based-exit-signal

Brian Peterson said the following:

>quantstrat, as described in the manual, is a signals-based framework. It is
not designed for filters based trades really.

>You could do what you want by using the delay argument to your exit rule.
Set the delay to be one day, and the prefer
argument to prefer a different price column.

>I'm not going to write it for you, but that is enough information to solve
your problem.

Now this was a solution to exit at a future time stamp. I want to exit the
*same* day (I am using daily data for my test) which is why I'm not sure if
setting a delay really works for what I want to do. Is this at all possible?

Appreciate the direction.
