漂亮的回測不等於真的有 edge。多數散戶「會賺」的策略其實是過擬合——那個 Sharpe 是掃了一堆參數挑出來最好的、是停損停利湊出來的假象、或只是運氣好的一段區間。 策略 Edge 驗證器用一整套統計檢定,幫你分辨「真訊號」還是「資料探勘出的雜訊」,全部只跑在你自己的報酬序列或權益曲線上: • 平穩 Bootstrap — 這條曲線跟零 edge 的雜訊分得出來嗎? • Deflated Sharpe — 扣掉「掃 N 組挑最佳」的選擇偏差後還站得住嗎? • PBO / CSCV — 回測期最強的參數,樣本外還是最強嗎? • Hansen SPA & Romano-Wolf StepM — 一籃子規則裡的贏家撐得過 data-snooping 嗎? • Bar-permutation MCPT — 利潤是訊號賺的,還是出場路徑湊的? • 樣本外分割 — 多少 edge 撐得過 holdout? 命令列 + JSON 輸出、自帶測試、標註學術出處。不需市場數據源、不需 API 金鑰、不需你的策略邏輯——你的數字全程不離開你的電腦。
Your backtest looks strong. But can you trust the evidence behind it? Check for holdout contamination, time leakage, cost-stress failures, concentration risk, and reproducibility issues — before you rely on the result.
This is the work I did for 10+ years. As a senior HR at top companies, I screened 10,000+ resumes and decided who made the shortlist — learning to tell real signal from keyword-stuffing, spot who'll actually perform, and stay consistent instead of going on gut. This Skill puts that same judgment to work on your hiring: it reads each resume against your role, ranks candidates with clear reasons, and flags who's worth interviewing and who isn't — so you build a sharper shortlist, faster.
Three independent AI reviewers — ATS Parser Realist, Recruiter Skeptic, Interview Predictor — catch what gets resumes filtered or ignored before you submit.
Most players lose games on the clock and blame the wrong phase. Clock Leak reads your Lichess games and measures exactly where your time goes - opening, middlegame, late game - against 93 real peers and a 27-player 2300+ panel. The popular advice "play faster in the opening" has zero measured effect (r=0.11). Middlegame overspend does (r=0.41). One numeric action per report, traced to your own data. No engine coaching, no rating promises.
Use when you paste today’s portfolio or watchlist snapshot before a daily review. For self-directed investors who want consistent questions, not a market-data feed. Proof: checks every pasted position on 8 fixed risk and thesis axes, then labels missing evidence [UNVERIFIED]. It reasons only from the numbers and notes you supply.
Structured audit of resume, LinkedIn profile and interview readiness. Career Readiness Score 0-100 across 5 areas, main Career Blockers, a rewritten draft of your weakest resume sections, and 10 prioritized fixes. Based on the assets you provide — does not guarantee interviews or offers (full disclaimer in the report).
Three independent AI reviewers audit a hiring decision for unverified skills, ignored red flags, and culture or cash-flow mismatch, then cross-examine each other.
