Yes you can use step -1. It depends on the scan but more often than not I
want to scan forward in time to today so if I get a buy signal on an
indicator I get the first occurance in the period being tested rather than
the last. In this case, its just a personal choice.

Note: this snippet is useful either way you count because If you index out
of range it doesn't work properly. Using Daysloaded to dynically keep track
of the # of days available based on what was asked for using the Daystoload
command. I use this in virtually all my scans and then can adjust the
period with confidence that I will get stocks that I want and my scans won't
crash.
