Wyckoff Reality Check — Does the Wyckoff Spring Actually Work?

The Wyckoff spring is one of the most-cited chart patterns in crypto — and one of the least measured. This tool marks every historical spring on the pair you pick, using exactly the mechanical rule we tested in a pre-registered study, and shows what actually happened next: against the pair's own base rate, look-ahead-free, after 0.20% round-trip costs. It is a base rate, never a recommendation.

The claim tested

Springs mark accumulation and precede outperformance

The measured result

No detectable positive edge across 10 survivorship-clean pairs; short-term negative

Against placebo

Did not beat a trivial RSI(14)-crosses-30 trigger

Method

Pre-registered rule, locked before the first number; Deflated Sharpe: fail

Not

A signal, a recommendation, or "Wyckoff theory disproved"

The rule is fully mechanical: a confirmed pivot low (6 bars each side) that is also the low of its 20-bar range becomes a support level; a spring is a bar that undercuts that level and closes back above it at the bottom of its range, with at most 3 prior breaks. Entry is the close of the trigger bar — never the low, which you only know in hindsight. Every detection uses only data available at the time (prefix-invariant by construction, proven in tests).

What the numbers show: across BTC, ETH and eight further pairs selected survivorship-clean as of 2020, the mean forward return after springs sat slightly below the unconditional base rate on 5- and 10-day horizons and was statistically indistinguishable at 20 days. A placebo arm — RSI(14) crossing above 30, deliberately trivial — produced comparable numbers. The pattern that chart courses sell as an accumulation footprint did not, in this locked test, earn its reputation. The tool lets you check any supported pair yourself, including pairs outside the study universe, labelled as such.
