  and [weekly close < weekly max(52,weekly close) *.5]
  
  or, if you want to run it daily instead of weekly
  
  and [close < max(251,close) *.5]
  
  Note: 251 is 52 weeks x 5 days - 9 market holidays.

  Also note, that this will pick up things that are making new 52 week lows, not just things that are near 50% down. If you want to limit the range of results, you can add a another line - for instance:
  
  and [close > max(251,close)* .4]
  
  i.e. things down not more than 60%
  
  If you want to find candidates in the group that might be turning up:
  
  and [sma(50, close) > 10 days ago sma(50,close)]
  and [sma(50, close) < 30 days ago sma(50,close)]
  
  You can play with any of the parameters to see what gives you more useful results.
