Price closing above the upper Bollinger Band, signaling an overextended move or strong momentum breakout.
The upper Bollinger Band equals the 20-period Simple Moving Average plus twice the rolling standard deviation of closes over the same 20 bars. on the 5-Min timeframe, each bar is one week, so the 20-period SMA spans roughly five months and the standard deviation reflects how volatile the stock has been over that window. A close above this band means price has pushed into territory that is statistically uncommon given recent volatility. The screen does not require the cross to be a new event; it flags any current close above the band, so a stock that has been walking the band for several weeks continues to appear.
Above Upper Bollinger is used two opposing ways: as a mean-reversion fade signal and as a momentum continuation filter. Mean-reversion traders see the extension as overstretch and look for signs of price returning toward the 20-week SMA. Momentum traders see the band break as a genuine breakout, treating band-walking as confirmation of a strong trend. The critical failure for mean-reversion is exactly that: some stocks walk the upper band for months in bull phases, and fading every close above it produces repeated losses. The critical failure for momentum is that not every upper-band break leads to continuation — many are exhaustion tops. Volume and broader market context separate the two scenarios. On shorter timeframes like the 5-minute, this condition is noisier and resolves faster. For the inverse condition, see Below Lower Bollinger. RSI Overbought Extreme can serve as a confirming momentum signal.
