TradFi Tick Shadow (NQ → BTC)

after a strong NQ (Nasdaq) day, BTC catches up post-close

Key metric

44 events / 180 days, follow rate 48% (random)

Why an edge should exist / hypothesis
Crypto as a 'shadow' of equities: BTC should inherit NQ momentum at the tick horizon.
Construction
NQ big day (|ret|>1%) → BTC catch-up post-close; desync filter.
Test data
44 events over 180 days.
Results
Follow rate 48% (random). Desync filter WR=40% (worse than random). Tick sell% post-close 47–53% — no directional flow.
Validation
No edge on any slice.
Root cause
Crypto is not a 'shadow' of equities at the tick level — the correlation is macro-horizon only.
Verdict
Dead (tick version). A separate lag-flip version is a marginal backlog.
