A worked example that explains the rule, not a stock price. Prices are in the right-hand column, and sessions sit under the volume bar.Hollow green candles closed above their open, and filled red candles closed below it.

What it is
Higher highs and lower lows in succession, so the shape opens like an upturned horn. Volatility rises with no direction · a market that has lost its price anchor.
When the trigger starts and when it fails
Signal
No approved signal: the volatility itself is the message.
No fixed invalidation level: the range widens with every leg.
Reading it stage by stage
ExpansionEvery high is higher and every low is lower · volatility climbs with no direction.
Touch pointsAt least five confirm the shape.
Practical reading⚠ Treat it as a volatility warning and cut position size, not an opportunity to grab: every leg looks like an excellent entry and the range swallows the stop.
Recognition rules
Two diverging lines: the upper rising and the lower falling.
At least five touch points (3 on one side and 2 on the other).
Volume tends to rise as the range widens.
Appears at market highs more than at lows.
Measuring the target
No reliable target · the volatility itself is the message, not the destination.
Where it fools you
The riskiest pattern to trade live: every leg looks like an excellent entry, and the widening range swallows the stop. The more useful reading is to treat it as a volatility warning and cut position size · not as an opportunity to grab.
