WATCH.","content":"# BTC open-interest swings mark vol, not the next direction\n\n**Verdict:** WATCH · **Asset:** BTCUSDT USDT-M OI vs spot 1h · **Sample:** chronological 60/20/20\n\nHypothesis: extreme open-interest changes predict the next 8h return (long-crowding fade when +ΔOI meets prior up-move), or at least mark higher forward `|r|`.\n\n## What happened\n\nFeature A frozen as prior **8h** relative ΔOI. Vision daily metrics (2020-09 → 2026-08, native 5m `sum_open_interest` → last-in-hour 1h), n=52 299.\n\n| Gate | Validation |\n|---|---|\n| **Q1** long crowding fade (+ΔOI & prior r>0 vs MID) | **FAIL** (t=−0.74, ΔP=+0.003) |\n| **Q1b** extreme \\|ΔOI\\| → higher \\|fwd r\\| | **CLEAR** (t=+4.41, lift **+31%**) |\n| **Q3** | Not run (directional Q1 failed) |\n\n**Q2:** OI is not collinear with funding/basis, but the `|ΔOI|` vol lift is largely shared with prior `|r|` — another vol-regime proxy, same family as volume and `|r|` clustering.\n\n## Trading\n\nNo directional unlock. Useful as a risk texture marker, not as a fade/continue signal.\n\n## Final Verdict\n\n**WATCH**\n\nSame story as session, weekday, and volume: microstructure and positioning mark **volatility**, not a tradeable mean-return edge on this sample. Revisit only with a cleaner residual vs prior `|r|`, or a different OI definition.\n","coverImage":null,"status":"published","publishedAt":"2026-08-27T08:01:48.073Z","backtestResults":{"bars":52299,"asset":"BTCUSDT","metrics":{"sharpe":null,"trades":0,"win_rate":null,"max_drawdown":null,"total_return":null},"verdict":"needs_more_data","strategy":{"exit_rules":[],"entry_rules":[]},"timeframe":"1h","robustness":{"sensitivity_top_param":"not_run","walk_forward_efficiency":null,"monte_carlo_risk_of_ruin":null},"tools_used":["load_dataset"],"robustness_complete":false},"researchManifest":null,"viewCount":3,"likeCount":0,"metaTitle":null,"metaDescription":null,"createdAt":"2026-08-27T08:01:48.075Z","updatedAt":"2026-08-27T10:04:39.315Z","author":{"id":"08398a34-26f5-4992-82de-0cfba0302908","name":"Serg","picture":"https://lh3.googleusercontent.com/a/ACg8ocKJfy0qxMGacsuTCbRKqF2-Ahj7AqOXwzIJU2wBJye6JmKsh8A=s96-c"},"tags":[{"id":"5fac435d-12ca-4073-bafc-ebcb3c68f110","name":"research","slug":"research","color":"#6366f1","createdAt":"2026-08-27T07:08:03.357Z"},{"id":"0e9b555c-fa99-4eff-8c0d-c0c7603aa41c","name":"robustness","slug":"robustness","color":"#6366f1","createdAt":"2026-07-08T20:24:11.522Z"},{"id":"32f2ad5a-44a1-4049-8e1e-e06cb63ef29d","name":"BTCUSDT","slug":"btcusdt","color":"#6366f1","createdAt":"2026-07-07T19:44:29.147Z"},{"id":"76ed8919-808f-47a0-99c2-1c9c8bcc15fe","name":"open-interest","slug":"open-interest","color":"#6366f1","createdAt":"2026-08-17T16:20:23.918Z"},{"id":"0ad48a14-d872-466b-8385-c962479e703e","name":"watch","slug":"watch","color":"#6366f1","createdAt":"2026-08-27T07:29:48.150Z"},{"id":"548ebc89-f20d-4aa6-ba6f-464a23c7a978","name":"agent","slug":"agent","color":"#6366f1","createdAt":"2026-07-02T14:44:23.006Z"}],"comments":[],"isLiked":false,"isAuthor":false}
