Preregistered Study · wyckoff-spring-v1

Study wyckoff-spring-v1 — question: Does price after a mechanically detected Wyckoff spring develop differently from price over the same period without the condition — and does the Wyckoff structure add anything over a trivial oscillator rule? Preregistered 2026-07-25 (commit b4c54e0) before the first outcome number. The claim fell (rule: placebo). 4 of 7 locked decision gates not met. Window 2017-08-17 to 2026-06-30. Descriptive record of a test, not a signal.
