Fit score101/100
Three successful defences of the same low — a base with more proof behind it than a double bottom. Trigger: A close above the neckline drawn through the intervening highs. Invalidation: A close below the three lows. A floor that fails on the third test usually fails badly.

Fit score73/100
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.
