filtering out non trading stocks

[paul <pwjc@xxxxxxxxxxxxxx>]

"(VOLUME > 0) OR (Ref(VOLUME,-1) > 0) OR (Ref(VOLUME,-2) > 0)

... to filter out stocks without trading for 3 days."

This doesnt filter out stocks that havent traded yesterday because if a
stock has not traded no data is updated, so the "volume>0" is applied to the
last days data, so if a stock hasnt traded for a week the "volume>0" is
applied to the last days data a week ago. 

But thanks for your help, I gave it a go.
