Range Expansion 14Cross-asset & regime

Timeframe M1 · unit ratio

What it measures

Compares the high-low range of the most recent 7 bars to the 7 bars before that, expressed as a ratio. Values above 1.0 indicate range expansion (recent volatility exceeds prior); below 1.0 indicates range contraction.

How Janira reads it (bullish vs bearish)

Values above 1.5 indicate significant range expansion - the market is covering more ground recently than it did in the prior equal-length window. Below 0.6 indicates notable contraction - price movement has compressed. A value near 1.0 means volatility is roughly stable across the two halves.

In plain language

Imagine the market as a rubber band being stretched and released. A value above 1.0 means the band is being stretched more than before (expansion). Below 1.0 means it is being pulled less (contraction). Near 1.0 means nothing changed.

Scenarios

• Ratio > 1.8: Sharp range expansion; the market is covering substantially more ground than in the prior 7 bars - volatility spike or breakout in progress.
• Ratio 0.8-1.2: Stable range environment; recent volatility is roughly comparable to the prior window; no structural change in activity level.
• Ratio < 0.5: Significant range contraction; the market has become notably quieter recently; compression phase, often precedes an expansion.
• Ratio expanding from < 0.7 toward > 1.5: Volatility is waking up from a compression; structural change in activity level is underway.
