[EquisMetaStock Group] Stocks >= 50% in value downwards per quarter

["mdtmn" <mdtmn@xxxxxxxxxxxxxxxx>]

Hi All,
      This is a scan that I use to find stocks that have moved 50% or
more per quarter downwards ( close to close)

Filter days:=60; 
C<=Ref(C,-days)-(Ref(C,-days)*0.5) 

as you can see it is approx ( and rough)and very dependent on what day
near the end of the quarter you run the scan

Example , this last quarter was 1st July to 30th Sep ,was 66 days
and running the scan  on the 24th , 25th, 26th, 29th and 30th of 
September will give slightly different results

Would someone be able to offer code that will scan for stocks in the
quarter that at any time during that time period moved down in value
by 50% or more, close to close ?
Thanks in advance
Michael B
