Cumulative Delta

Net aggressive buying minus selling over time. Divergence with price = warning: price up but delta flat means rally has no buyers — fade candidate. Price flat but delta up = stealth accumulation.

Absorption

Large hidden seller absorbing every buy at the ask without price moving up = bearish iceberg. Same in reverse for bullish. The tell: giant cumulative volume at one price with no breakout.

Imbalance Stacks

3+ consecutive price levels with >3x bid/ask imbalance = directional pressure. Bull stacks above value, bear stacks below, set up the next 5-15 min directional move.
