FTB-C000645 / Implementation concept

Prior Rise Requirement

Prior Rise Requirement is the minimum directional rise required before a double-top candidate is considered a reversal structure.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

A double top needs a qualifying lead-in rather than two highs inside an arbitrary range.

Technical

The canonical contract requires prior directional move >= 0.03 before the first structural high.

Scope

This filter is an implementation boundary, not evidence that every reversal needs the same trend length.

Examples

  • A reviewer computes Prior Rise Requirement on a deterministic close fixture and checks pivot timing, threshold equality, neckline behavior, and rejection diagnostics before publication.

Common misconceptions

  • This filter is an implementation boundary, not evidence that every reversal needs the same trend length.

  1. Members' Guide to 2021 Refresher Readings CFA Institute · first party methodology

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: The curriculum does not prescribe this package's pivot window, numeric thresholds, causal state machine, or performance claim.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: The paper's smoothing, sample, and empirical design are not copied into this package and do not validate its thresholds.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: Platform display behavior does not establish financial usefulness or predictive value.

  4. scipy.signal.find_peaks SciPy · first party technical publication

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: This retrospective signal function is not itself a causal OHLC pivot detector.

  5. Pine Script pivot techniques TradingView · official platform documentation

    Supports: preferred label, short definition, technical definition, variant distinction

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

  6. Zig Zag indicator QuantConnect · official platform documentation

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: This package selects a close-only percentage-reversal variant and documents the difference.

    Supports: preferred label, short definition, technical definition, variant distinction

    Limits: A maintained implementation is evidence for one convention, not a universal market rule.
