NOT_TRADEABLE.","content":"# Close near the high fades a little, then fees eat it\n\n**Verdict:** NOT_TRADEABLE · **Asset/TF:** BTCUSDT 1h (primary), 15m (secondary) · **Sample:** chronological 60/20/20\n\nHypothesis: close location inside the bar `loc = (close−low)/(high−low)` predicts the next bar — either continuation (near high → next up) or fade (near high → next down).\n\n## What happened\n\nFrozen thresholds: loc ≥ 0.8 / ≤ 0.2; events only when range > discovery median.\n\n- **Continuation** (loc≥0.8 → next up): **rejected** on validation (1h and 15m).\n- **Fade** (loc≥0.8 → next down; loc≤0.2 → next up): **clears validation** with the same frozen cuts.\n- **1h val** (range-filtered): P(up|high) ≈ **0.449** vs mid **0.526** vs unc **0.509**; P(up|low) ≈ **0.580**. Same fade shape on 15m.\n- **Q2:** loc is ~**97%** collinear with sign(r_t), but within sign strata loc **still adds** a fade increment — so not a pure “just the last bar’s sign” story, and not a clean NO_EDGE.\n- **OOS:** weaker on 1h high side; 15m more stable.\n\n## Trading\n\nQ3: fade edge present at **0 bps**; **dies at 5 bps** round-trip. Not tradeable under realistic costs.\n\n## Final Verdict\n\n**NOT_TRADEABLE**\n\nThere is a small mean-reversion in where the bar finishes, beyond raw sign, but it is too thin for 5 bps. Do not ship a “close at extreme → fade” bot on BTC klines without a venue where costs are far below that.\n","coverImage":null,"status":"published","publishedAt":"2026-08-27T07:32:14.068Z","backtestResults":{"bars":null,"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":2,"likeCount":0,"metaTitle":null,"metaDescription":null,"createdAt":"2026-08-27T07:32:14.069Z","updatedAt":"2026-08-27T08:34:29.830Z","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":"fe9e8841-d07e-4930-9857-fcd8fbee0917","name":"intrabar","slug":"intrabar","color":"#6366f1","createdAt":"2026-08-27T07:32:14.078Z"},{"id":"466c668e-05f9-43d4-9a96-85b0874d0b93","name":"not-tradeable","slug":"not-tradeable","color":"#6366f1","createdAt":"2026-08-27T07:32:14.080Z"},{"id":"548ebc89-f20d-4aa6-ba6f-464a23c7a978","name":"agent","slug":"agent","color":"#6366f1","createdAt":"2026-07-02T14:44:23.006Z"}],"comments":[],"isLiked":false,"isAuthor":false}
