What is absorption in trading?
In one line: Absorption is when a big wall of resting orders soaks up heavy buying or selling, so lots of volume trades but price barely moves.
A simple example
Price drops to 50.00. Sellers keep hitting the market with sell orders. Over five minutes, 400,000 shares trade at 50.00 to 50.05.
On a normal day, that much selling might push price down a dollar. This time it barely moves. Someone has a large buy order resting at 50.00 and is filling every seller.
That's absorption. The selling was real. It just got soaked up.
What it looks like on a chart
- A tall Volume bar with a small candle body.
- Several candles in a row that stall at the same price.
- Long Wicks poking past the level, then closing back inside.
Traders who read Order flow tools, like a Footprint chart, see it more directly: big numbers on one side, no follow-through.
Why it matters
Absorption shows you where a big player may be defending a price. If sellers can't push through, they may give up. Then price can turn around from that level, the way Support works.
It also works in reverse. Buyers piling in at a Resistance level with no progress can be a sign that a large seller is there.
A common mistake
Treating absorption as a sure turn. A big order can be pulled at any moment. And absorption can end with the wall finally breaking, which often leads to a fast move through the level.
Use it as a clue, not a signal. Wait for a candle body to close back away from the level before you act, and set your Stop loss from the chart.

Questions
Is absorption the same as support?
Not exactly. Support is a price level where price has turned before. Absorption is what you might see happening at that level: heavy orders being soaked up without price moving.
Can you see absorption without special tools?
Partly. A big volume bar with a small body, at a level that holds, is the basic sign. Order-flow tools show it in more detail.
Does absorption mean a reversal is coming?
No. It means one side is meeting a lot of resistance. The level can still break, so a stop is always part of the plan.
