Inverse H&S Prior Decline Requirement

Inverse H&S Prior Decline Requirement is the minimum decline before the left shoulder required for a bullish inverse head-and-shoulders candidate.

Advanced 1 linked topicEvidence-reviewed

Definitions

In plain terms

The structure represents a reversal after a qualifying decline, not any five lows and highs.

Technical

The canonical prior directional move before the first shoulder must be >= 0.03 in the downward direction.

Scope

The prior-trend filter is an implementation choice, not a universal reversal law.

Examples

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

Common misconceptions

  • The prior-trend filter is an implementation choice, not a universal reversal law.
