From 5ca33690d0bd03a066f2be061fcb83281824548c Mon Sep 17 00:00:00 2001 From: kjh2064 Date: Sun, 2 Aug 2026 12:29:48 +0900 Subject: [PATCH] False Exit Analysis: Re-entry success rate validation MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Implements strategy robustness check for portfolio false exits: Features: - FalseExitAnalyzer: Calculate re-entry success rate ├─ Exit detection (Sell + Exit signals) ├─ Re-entry tracking (within 60-day window) ├─ Success calculation (profitable re-entry %) └─ Average days out of position Metrics Output: - FalseExitCount: Total exits - ReentryCount: Exits with re-entry signal - ReentrySuccessCount: Profitable re-entries - ReentrySuccessRate: Decimal 0-1 (percentage) - AverageDaysOutOfPosition: Days between exit and re-entry Contract: - src/KArtSell.Host/Features/ShadowRun/FALSE_EXIT_ANALYSIS_CONTRACT.md Implementation: - src/KArtSell.Modules.ModelOperations/ShadowRun/FalseExitAnalyzer.cs Stub implementation (ready for refinement) Analyzes order/signal/portfolio history Integration Point (Pending): - ShadowRunJob Phase 4.5 (after metrics, before validation) - Will populate ShadowRunResult.FalseExitAnalysis Test Status: 84/84 PASSING (no new tests added, baseline preserved) AGENTS.md v16.0: ✅ Necessity: Required for strategy activation gating ✅ Safety: Read-only analysis (no state changes) ✅ Simplicity: Clear metric definitions Next Steps: 1.
