With the exception of the Lower Bollinger Band Walk scan, these scans identify stocks which have not yet broken down but may be poised to do so in the near future. They are in some kind of basing or consolidation pattern and have not yet fallen past their sell points. Stocks found via the Lower Bollinger Band Walk scan will most likely already have broken sown. However, it's possible that when a band walk just begins that a stock may not have yet broken a price support level.
