What is the look-back period for the New High-New Low indicator? Can it be done in MetaStock?

The new highs and new lows are for 52 weeks. That is, today's high is a new high for the last 52 weeks or today's low is a new low for 52 weeks.

I am not a Metastock user, but I understand it can interrogate a database, so it should be able to filter out a list for you. Insight Trader also gives the total number of hits for a filter run. You may have to add them up in Metastock. You will, of course, need a database of all stocks on the ASX.
