Support & Resistance: The Battlefield

These are the invisible walls where the war between Bulls and Bears is fought.

Definitions

  • Support (Floor): A price level where buyers consistently step in. Price bounces UP from here.
  • Resistance (Ceiling): A price level where sellers consistently step in. Price rejects DOWN from here.

The "Flip" Concept

Once a Resistance is broken, it becomes Support.
Once a Support is broken, it becomes Resistance.

"Old Resistance becomes New Support."
