ZigZag Repaint Scope is the portion of a ZigZag output that may change before an endpoint is confirmed.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

Only the current provisional endpoint is expected to move during a clean unrevised run.

Technical

Confirmed pivots remain locked while provisional index and price may update; source revisions can require replay from the earliest dependent state.

Scope

A final chart line can hide the historical repaint scope and mislead point-in-time analysis.

Examples

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

Common misconceptions

  • A final chart line can hide the historical repaint scope and mislead point-in-time analysis.
