Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

The anchor starts the state machine but is not itself a confirmed reversal.

Technical

The anchor initializes running high and low state; confirmation requires a later opposite move and minimum bar distance.

Scope

Calling the anchor a pivot overstates what the first observation proves.

Examples

  • A reviewer computes ZigZag Anchor on a small deterministic fixture and checks timing, units, and boundary behavior before publication.

Common misconceptions

  • Calling the anchor a pivot overstates what the first observation proves.
