    Thanks for that. Seems like what this does is look for a breakout in a different way.
Yep, if you set the Range No of days = 5 or 10 you look further back for the setup.  
  As far as I know Scan is used to ...
  1.Create composites using the Addtocomposite function
  2.To run a daily (or other time period) for signals as per your buy signal..  
  The Scan button will only work if your code has a buy statement in it.  
  So if you add  
  Buy = filter;   
  after the filter statement then you will be able to use the Scan button..
  Double click on one of the returned tickers, and the chart will show  with an arrow/arrows in the place where your buy or filter conditions  were met.   
 Exploration does not need a buy condition. It  returns a list of tickers based on your Filter conditions and returns  information for these in the columns.
  So for Explorations you need a Filter
 statement and at least one Addcolumn statement.
  Explorations are a good way to output numbers into the columns to see  if your code is doing what you think it should be doing. Or to derive  data which you wish to export into a CSV file for example.  
  So if you have code which has ...
  1.filter and Addcolumn statements AND
  2.Buy statement  
  you can use this as Scan or Exploration.  
  If you also have ...
  3.Plot statements then you can use the same whole afl file for Scans  and Explorations and for the old Indicator builder or plotting function.  
  If your code also has a Sell condition you can use it for backtesting.  
  Happy trading.

 Just  on that point - what exactly IS the difference between scan
 and  explore?  I know that if I go to 'Scan' with your formula, I get  an error about something not being defined, but it works perfectly as  an "Explore".  Never been clear on the difference and the use of  the terminology there - to me, a scan and an exploration would seem to  be the same thing....  but what do I know? :)
