This screen finds stocks whose price has just bounced up from the upper Bollinger Band. Bollinger Bands(20,2), created by John Bollinger, plot a 20-day simple moving average as the middle band and upper and lower bands two standard deviations away, so the bands widen when volatility rises and narrow when it falls. A bounce off the upper band from above is a sign of a strong band walk in an uptrend.
