Every range eventually contracts before it expands. When one bar's high-to-low range is tighter than each of the last several, that tightness is the setup, not noise to filter out. The break of that one narrow bar is the trade.
“The break needs volume stepping up from the prior bars, not a wick through the level. Only the volume-backed break counts.”Jason Parker · Founder
The narrow range breakout compares a single bar's range, its high minus its low, against the same measurement on each of the bars before it. When the current bar's range is the tightest of the last seven (the classic NR7 test popularized by floor traders decades ago, adapted here to a 1 to 5 minute intraday bar instead of a daily one), it marks a coil: volatility has compressed to a multi-bar low right before it typically expands again. The setup does nothing with the narrow bar itself. It waits for whichever side breaks first.
Midday Range Compression fades a specific stretch of the clock, the post-open lull, regardless of how any single bar's range compares to the ones around it. Bollinger Band Squeeze Breakout measures compression through a volatility indicator, band width relative to its own recent history, not the raw bars themselves. Inside Bar Breakout requires one exact two-bar relationship, the whole bar sitting inside the prior bar's range. Narrow range breakout needs neither an indicator nor a two-bar containment rule, just the tightest range of the last seven bars, wherever in the session it happens to show up.
| Entry | At the narrow bar's high (long) or low (short), on a break with volume stepping up from the prior several bars, not on a wick through the level |
| Exit | First target equal to the width of the two or three bars right before the narrow bar, the range that just compressed away; trail behind new higher lows (or lower highs) if the move keeps extending |
| Stop | Just past the opposite side of the same narrow bar, since a full round trip back through it means the compression resolved the other way |
An illustrative example built to show the setup’s shape. Not historical price data, and not tied to any specific ticker.
A narrow bar during a dead, low-volume stretch, the last few minutes before a holiday close, the middle of an illiquid afternoon, can sit tight for reasons that have nothing to do with a coiling market, and the break that follows can be just as thin. This also needs enough bar history to compare against; the first seven bars of a session haven't built that history yet, so this setup doesn't apply right at the open. A false break through the narrow bar's edge that snaps back inside it whipsaws the trade with no warning beyond the stop already in place.
None of this works without the framework underneath it. Read risk management next, or run your own numbers in the position-size calculator.
Common questions about trading this setup, answered straight.
Its high-to-low range has to be the tightest of the last seven bars on the chart, not just visually small. That comparison is what separates this from any other quiet-looking candle.
Entry sits at the narrow bar's high for a long or its low for a short, triggered by an actual break with volume, not a brief wick through the level. The stop sits just past the opposite side of that same narrow bar.
When the range compressed for reasons that have nothing to do with a market about to move, thin holiday-session liquidity being the most common one, or when the break through the narrow bar's edge snaps back inside it instead of holding.
