Reference values based on Bulkowski's "Encyclopedia of Chart Patterns". Data is primarily from U.S. markets and may differ for other markets.

A pattern where a U-shaped rounded bottom forms during an uptrend, after which the trend continues. A pullback from a high creates a gentle curve to find a bottom, then rallies back above the previous high to complete the pattern. Named for its scallop shell-like rounded shape, it may appear in succession.

Formation Conditions

  • An uptrend must precede the pattern
  • The decline from the high must form a U-shape (rounded bottom)
  • The bottom must be a gentle curve, not a V-shape
  • Price must rally and break above the previous high
  • The left side of the scallop is often steeper than the right

Entry Condition

Enter long when price clearly breaks above the previous high on a closing basis. A volume-accompanied breakout after confirming the U-bottom bounce is more reliable.

Target Calculation

Project the range from the scallop's high to its bottom upward from the breakout point (previous high). For example: high at 1000, bottom at 880, range of 120, target at 1120.

Stop Loss Rule

Place a stop-loss slightly below the U-bottom's lowest point. Or project 50% of the scallop's range downward from the breakout point.

Volume Profile

Volume decreases at the U-bottom and gradually increases during the rally. A volume surge when breaking above the previous high enhances reliability.

False Signal Detection

  • V-shaped sharp bounces are different from scallops
  • An extremely short bottom period reduces reliability
  • Breaking the previous high without volume may be a false signal
  • If the uptrend is weak, it may be a double bottom rather than a scallop
  • Less effective in a broadly bearish market
