You could explicitly provide the dates for which you test in a Personal Criteria Formula and use it as an EasyScan Condition:
C'11/28/08' > C'12/31/08' AND C'12/31/08' < C'01/30/09'
You can keep adding dates to check, but if you go back too far, the formula will not be calculated for symbols that weren't around for the older dates.
It is possible to write Personal Criteria Formulas based on past dates. You may wist to review the following section of the Online Help Files:
Days Ago parameter
There are two distinct ways to use historical data with Personal Criteria Formulas.
Any criteria can be used to scan X number of days back by adding '.XX' where XX is equal to the number of market days past to calculate for. An example of this is (AVGC21.21), which is a 21 day moving average 21 of close, 21 days ago. This use of historical data always refers to the market day XX number of days ago (in this case, 21). If you wish to use a specific date’s data, use the option detailed below.
The other method of using historical data is by specifying a precise date in history to use. For example, (AVGC21.'11/13/08') will provide a 21 day moving average of close for November 13, 2008 (the period should be used in cases where the first method requires a period and not used when the first method does not use a period). Always confirm that the date you wish to use using this parameter was a market day.
