Order flow: Stacked Imbalance

Sequences of footprint imbalances that signal decisive pushes.

In the footprint an imbalance is a level where bought volume clearly exceeds sold volume (or the other way round). When several imbalances of the same type stack up on consecutive levels, it is called a stacked imbalance.

What it is for

Identifying the zones where one side pushed decisively: they often act as supports/resistances and signal the direction of the pressure.

How to read it

  • Imbalanced levels are highlighted on the footprint bar.
  • A stack of consecutive imbalances (three or more, say) marks a zone of stronger push.

Parameters

  • Threshold %, how far one side must exceed the other to count as an imbalance.
  • Mode, diagonal or horizontal comparison between bid and ask.
  • Minimum volume, ignores levels that are too thin.
  • Colours and stack highlighting.
