Three troughs with the middle one deepest — the classic bottoming pattern. Trigger: A close above the neckline, ideally on rising volume. Invalidation: A close below the right shoulder, and certainly below the head.

Fit score74/100
Price grinding higher inside two rising lines that are closing together — an advance running out of air. Trigger: A close below the rising lower boundary. Invalidation: A decisive close above the upper boundary, which turns the wedge into an ordinary acceleration.
