Scanning for trends

  You could write a scan that looks at a long term moving average, like the daily 200 or the weekly 40 at several points in time, and compares the later points to the earlier points. If you want an up trend, the later points should be greater; for a down trend, they should be less.
  
  So, for an uptrend, something like
  
  and [sma(200, close) > 21 days ago sma(200,close)]
  
  and [21 days ago sma(200, close) > 63 days ago sma(200, close)]
  
  and [63 days ago sma(200, close) > 126 days ago sma(200, close)]
  
  etc.
  
  For a weekly version, use "weeks ago" and "weekly close".
  
  Another possibility is to test for a stochastic level, with custom parameters:
  
  and [min(251, Fast Stoch %K(251, 1)) > 70]
  
  This says the close has been in the upper 30 per cent of the 251 day range for 251 days.
  
  You can edit all the parameters, including the interval days (21 - 63, 63 -126, 251) and the sma and Stoch lengths (200, 251) to see what happens.

  Another possibility for up trends:
  
  
  and [slope(50, sma(200, close)) > .05]
  
  For down trends:
  
  
  and [slope(50, sma(200, close)) < -0.15]
  
  Again, play with the parameters 50, 200 and .05, -.015
