A worked example that explains the rule, not a stock price. The circle marks the first close beyond the level. The blue line is the target. The orange line is the invalidation. 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
Highs and lows both rise, but the lows rise faster so the range contracts. A rise losing momentum: each wave is shorter than the last.
Apparent riseHighs and lows rise · it looks healthy to a casual reader.
SqueezeThe lows rise faster, so the range narrows and volume falls. That is the warning: read the width, not the direction.
BreakBelow the lower leg · the target is the wedge's maximum height subtracted from the breakdown point.
Recognition rules
Two rising lines that converge · the lower one is steeper.
The range narrows as the pattern develops.
Volume falls during the rise · a clear warning.
Confirmation is a break below the lower side.
Measuring the target
The wedge's maximum height is subtracted from the breakdown point.
Where it fools you
The most dangerous thing about it is that it looks like a healthy rise. A casual reader sees higher highs and buys, while the shrinking range and drying volume say the opposite. Read the width, not the direction.

We do not detect chart patterns with a numeric rule: telling them apart takes judgment on the chart. Candlestick patterns with a numeric rule are detected daily by the candlestick pattern scanner.
