This screen finds a SuperTrend bullish reversal: the price has just closed above the SuperTrend line, which flips below the price. SuperTrend(3,7) is a trend-following line built from the Average True Range: it sits below the price in an uptrend and above it in a downtrend, at a distance of three times the 7-day ATR, and flips sides when the price closes through it. The flip is a buy signal that a new uptrend may be starting.
