Yesterday was NR7; breaking above prior day’s high — strong volatility expansion bullish.
The NR7 condition requires today's range to be smaller than yesterday's AND smaller than each of the prior 2-to-6 sessions -- confirming the tightest bar in seven consecutive days. The directional filter checks that the current close is above the prior day's high, confirming buyers have taken control beyond the compression zone. Volume must exceed the 20-period average, filtering out low-conviction moves. The four filters together target a specific event: a compressed market suddenly releasing to the upside with participation. Compression alone (without the break and volume) is the NR7 Squeeze screen. This screen adds the resolution trigger.
on the Daily timeframe, NR7 Bull Break is used by swing traders targeting multi-day continuation moves. The setup's strength is that compression periods often precede the largest single-session gains, since trapped sellers above the range provide fuel for the breakout. The key failure mode is a one-day pop with immediate reversal -- the stock breaks above the prior high, triggers alerts, then closes below it by the end of the session or gaps down the next morning. Checking that the break occurs in the first half of the trading session (rather than a last-hour spike) improves follow-through rates. Earnings-driven NR7 breaks carry more risk because the move is news-dependent, not technically driven. Compare with Bollinger Squeeze Break Bull for momentum-confirmed breakouts and High ATR for stocks already in high-volatility regimes.
