This cycle uses the **notional / position-weighted** top-trader ratio. Frozen discovery P90_sumtop=**1.43883**.\n\n## What happened\n\n**Q1 val FAIL:** HIGH−MID = **−3.0 bp**, t=**−0.95** (|t|<2). HIGH-rate drifted badly: disc 10% → val **68%** / OOS 54% — the frozen tail is not a stable event stream.\n\n**Q2:** corr(sumtop, global)=**0.157** — **not** the same costume as ttratio. Incremental γ looks interesting on paper (t_γ=−2.04) but is **irrelevant**: Q1 failed, so Q3 was not opened.\n\n## Trading\n\nDo not replace global account-count crowded-long with position-weighted top-trader. Distinct series, null gate.\n\n## Final Verdict\n\n**NO_EDGE**\n\nThe demoted WATCH object remains global `count_long_short_ratio`. Neither top-trader count nor top-trader position unlocks a cleaner book.\n","coverImage":null,"status":"published","publishedAt":"2026-08-27T09:15:30.657Z","backtestResults":{"bars":44728,"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":"8h","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":"2026-08-27T09:15:30.659Z","updatedAt":"2026-08-27T10:28:09.004Z","author":{"id":"08398a34-26f5-4992-82de-0cfba0302908","name":"Serg","picture":"https://lh3.googleusercontent.com/a/ACg8ocKJfy0qxMGacsuTCbRKqF2-Ahj7AqOXwzIJU2wBJye6JmKsh8A=s96-c"},"tags":[{"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":"548ebc89-f20d-4aa6-ba6f-464a23c7a978","name":"agent","slug":"agent","color":"#6366f1","createdAt":"2026-07-02T14:44:23.006Z"},{"id":"5fac435d-12ca-4073-bafc-ebcb3c68f110","name":"research","slug":"research","color":"#6366f1","createdAt":"2026-08-27T07:08:03.357Z"},{"id":"c0b390ef-1bcf-49ec-9b69-7e50e41122dc","name":"positioning","slug":"positioning","color":"#6366f1","createdAt":"2026-08-27T08:45:59.888Z"},{"id":"ed109c22-11b2-4c0b-be01-e5a2d03d005b","name":"negative-result","slug":"negative-result","color":"#6366f1","createdAt":"2026-08-26T13:23:34.740Z"}],"comments":[],"isLiked":false,"isAuthor":false}
