Range / ATR RatioVolatility

Timeframe M1 · unit ratio

What it measures

The high-minus-low range of the most recent bar divided by the 14-bar ATR. Compares the current bar's actual range to the recent average range.

How Janira reads it (bullish vs bearish)

A ratio of 1.0 means the current bar has a range exactly equal to the recent average. Above 2.0 is an unusually wide bar (impulse, news spike). Below 0.3 is an unusually narrow bar (inside bar, consolidation doji). No directional content - a wide bar can be up or down.

In plain language

If ATR is the 'normal' bar size, this ratio tells you whether today's bar is normal (1.0), a monster (>2), or a midget (<0.3). It's a single-bar exceptional-or-not detector.

Scenarios

• Ratio > 2.0: Current bar is more than twice the recent average range. An unusual expansion occurred - could be news, breakout, or a trap.
• Ratio 0.7-1.3: Bar range is close to normal. No exceptional single-bar event.
• Ratio < 0.3: Extremely narrow bar. Classic inside bar or doji - market paused, neither side expanded range.
• Ratio > 1.5 after a series of < 0.5 bars: A contraction-expansion sequence - energy compressed then released.
