No stock is in NR4 Bull Break on the Daily chart right now. The screen re-evaluates on every daily close; the app alerts the moment one enters.
The NR4 condition checks that the prior session's range was smaller than each of the previous three sessions -- confirming a four-session compression. "Close crosses above prior high" is a cross-detection filter, not just a comparison: it requires the close to be below the prior high on the previous bar and above it on the current bar. This fires on the exact bar of breakout, not on any bar after it. Volume above the 20-period average confirms the breakout has real participation.
NR4 Bull Break targets a single specific event: the first session of upside expansion after a compression period. Traders who use this are typically looking for entries with well-defined risk -- the NR4 bar's low serves as the natural stop. The main failure mode is the false breakout: price crosses above the prior high, triggers the screen, then reverses and closes back inside the NR4 bar range by session end. This is especially common when the breakout occurs late in the trading session or on a gap-up open with no intraday follow-through. Traders mitigate this by requiring the cross to happen before the last 30-60 minutes of the session and by watching volume develop in real time. For the bearish mirror setup, see NR4 Bear Break. For compression over a longer seven-session window, see NR7 Bull Break. For post-break continuation confirmation, see High ATR and Bollinger Squeeze Break Bull.
