Absorption

The outcome when incoming aggression is fully matched by available opposing liquidity, so the best price does not need to relocate.

Full Explanation

Absorption happens when aggression arrives and the resting liquidity at a price is sufficient to fill it. Transactions are taking place, but the available orders do not run out, so the bid or ask does not need to move to another price. The aggression has been absorbed.

On a chart, absorption can appear as a stall, repeated overlap, a wick, or a failure to continue relocating despite continued activity. None of those shapes proves what individual participants intended. They are simply evidence that aggression was unable to keep taking new territory.

Absorption also consumes some of the orders doing the absorbing. That matters because a level that absorbed aggression once is not guaranteed to do it again. The remaining liquidity may be smaller, new orders may have been added, or participants may withdraw entirely. The useful question is not whether a level is strong. It is whether aggression is being absorbed when it arrives there now.

Every transaction has both a buyer and a seller. That's not insight — it's arithmetic. The question that actually matters is different, and until you're asking it, you're working with the wrong map.
