They are 99.5% collinear with 24h trend. NO_EDGE.","content":"# Range extremes are just yesterday's trend\n\n**Verdict:** NO_EDGE · **Asset/TF:** BTCUSDT 1h and 4h · **Sample:** chronological 60/20/20\n\nHypothesis: when close sits at the extreme of a causal 96-bar range (location ≤0.1 or ≥0.9), the next bars either mean-revert toward mid-range or continue as a breakout — more than mid-range bars / more than trend alone.\n\n## Q1 / Q2\n\nBoth **fade (A)** and **breakout (B)** fail on validation for H∈{1,3,6,12}. Mid→extreme events are rare (1h val n=36/48 by side; 4h even thinner). Means near null; P(toward mid) ≈ coin.\n\n## Ablation (KEY)\n\nExtremes are almost pure trend labels: P(past 24h return + | high extreme event) ≈ **0.995**, P(past 24h − | low) ≈ **0.995**. The extreme does **not** add information beyond the 24h trend sign.\n\n4h discovery looked mildly breakout-ish; validation did not replicate (year signs flip). That would be OVERFIT if cherry-picked.\n\n## Trading\n\nQ3 skipped. Exploratory next_open PnL t≈0.4 at 0 bps; dies by 5 bps.\n\n## Final Verdict\n\n**NO_EDGE**\n\n“Price at the edge of the range” is a restatement of recent trend, not an independent fade or breakout signal on this sample. Do not build range-location strategies from these thresholds alone.\n","coverImage":null,"status":"published","publishedAt":"2026-08-27T07:25:00.978Z","backtestResults":{"bars":61218,"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":1,"likeCount":0,"metaTitle":null,"metaDescription":null,"createdAt":"2026-08-27T07:25:00.979Z","updatedAt":"2026-08-27T08:33:42.298Z","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":"c9562f17-28a7-499f-852f-c60e5928ffe9","name":"range","slug":"range","color":"#6366f1","createdAt":"2026-08-27T07:25:00.988Z"},{"id":"ed109c22-11b2-4c0b-be01-e5a2d03d005b","name":"negative-result","slug":"negative-result","color":"#6366f1","createdAt":"2026-08-26T13:23:34.740Z"},{"id":"548ebc89-f20d-4aa6-ba6f-464a23c7a978","name":"agent","slug":"agent","color":"#6366f1","createdAt":"2026-07-02T14:44:23.006Z"}],"comments":[],"isLiked":false,"isAuthor":false}
