A bearish reversal pattern that signals the start of a downtrend following an extended consolidation period.
It is a YC bearish trend reversal pattern comparable to an imaginary right triangle. It is made up of two sides joined at a 90 degree angle and linked by a hypotenuse.
Horizontal Line (Long side): Connects two or more near-equal market lows. (Line 1)
Vertical Line (Short side): Extends from the horizontal to the highest market point above it. (Line 2)
Hypotenuse: Connects descending market highs, indicating bounces above the horizontal. (Line 3)
Wait for at least two valid bounces and a clean structure before planning entry.
A minimum of two, ideally three, descending bounces from the left must occur above the horizontal river-line support.
Velocity within bounces: Rises from the horizontal river-line support to highs (B1, B2, B3) should be slower than the declines back to it (see candle counts in the pic).
A bearish setup is confirmed after breakdown and controlled retest near the key level. Place stop loss above invalidation.
A sell signal is generated when the price closes below the horizontal line after at least two bounces.
A stop loss should be set just above the most recent bounce high before the breakout.

Historical cases show meaningful downside when confirmation and risk management are respected.
