FTB-C000649 / Implementation concept

Pattern Confirmation Window

Pattern Confirmation Window is the finite period during which a qualified candidate may confirm by crossing its neckline.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

If no close crosses before the deadline, the candidate expires instead of remaining valid forever.

Technical

Confirmation is allowed through last_pivot_index + max_confirmation_bars; rejection occurs on the following bar.

Scope

Expiry is part of the detector contract and changes whether a late break is accepted.

Examples

  • A reviewer computes Pattern Confirmation Window on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.

Common misconceptions

  • Expiry is part of the detector contract and changes whether a late break is accepted.

    Supports: preferred label, short definition, technical definition

    Limits: The package freezes its own equality, separation, and OHLC policies rather than claiming one universal pivot definition.
