A close below the lower band is a statistically unusual amount of selling; closing back above it is the band-trader's classic entry, because the unusual condition resolved upward. The one thing to respect is that in a genuine downtrend price can ride the lower band for weeks — this scan finds the re-entry, and the re-entry failing is itself information.
