Spots where heavy volume hits a level but price refuses to go — someone large absorbing every order, which often marks the turn.

• Bubbles — volume-scaled circles at the wick. Bigger bubble = heavier volume vs normal. Upper wick = sellers absorbing buyers; lower wick = buyers absorbing sellers.

• Signals — the A+ filter: fires only when volume ≥3σ and the rejection wick is ≥35% of the bar and the close confirms it. Marks a 🔺/🔻 "ABS" triangle. Confirmed on bar close, no repaint.

• Alerts — separate for bubbles and signals.

• Colors — all customizable.

Use it: wait for a signal at a level you already care about (prior high/low, gamma level, print), then trade the rejection with your stop past the absorbing wick. The signal says someone defended it; your level says where.
