Absorption

Absorption #

Definition #

The absorption signal visualizes the point where absorption occurs in your instrument. The signal will print immediately and remain historically on the chart at the time and price level where the absorption occurred. You can also adjust the settings to receive alerts for the signal.

Strategy #

When the price is absorbed, look for a price reversal.

Absorption Signal  #

The market volume is measured for a defined period of time for an absorption signal. Once the “Trigger Volume” value is reached or exceeded within the time parameters, the signal is the output. It can occur with one or more large limit orders or an iceberg.

Absorption happens when a lot of volume gets „absorbed“ by limited orders (or icebergs) without moving the price.

In practice, the price might be allowed to move 1 or 2 ticks, which we still call absorption.

Scheme #

In this example, a total volume of 850 lots was absorbed on a single price level, while 500 lots are still in the limit order book.


There are two absorption signals together. One with 1.526 lots and the other with 780 lots. All market volume was absorbed. After that, the price goes up.
