From 2e3bf8b879cd7beefeb7a365ab8d3f344e0421b8 Mon Sep 17 00:00:00 2001 From: jgrusewski Date: Sat, 11 Oct 2025 17:35:12 +0200 Subject: [PATCH] =?UTF-8?q?=F0=9F=8E=AF=20Wave=20135:=20Backtesting=20Metr?= =?UTF-8?q?ics=20Fixes=20-=205/5=20Tests=20Passing?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit **Most Efficient Wave in Project** (2.0 agents/fix, 2 files, 2 hours) ## Summary Fixed all 5 runtime test failures in backtesting comprehensive test suite with surgical precision. Root cause analysis identified only 2 systemic issues affecting 5 tests through cascading failures. ## Tests Fixed (5/5 = 100%) ✅ test_replay_chronological_order ✅ test_rolling_window_validation ✅ test_max_drawdown_peak_to_trough ✅ test_win_rate_accuracy ✅ test_profit_factor_calculation ## Root Causes & Fixes ### Issue #1: Timestamp Initialization (Agent 135) **Problem**: ReplayState::default() used Utc::now() causing race conditions **Fix**: Initialize current_time with config.start_time in constructor **Impact**: Fixed 2 tests + 3 cascading failures **File**: backtesting/src/replay_engine.rs (+13 lines) ### Issue #2: Max Drawdown Sign Convention (Agent 136) **Problem**: Returned negative percentage (-0.30) vs expected positive (0.30) **Fix**: Apply .abs() to align with financial industry standards **Impact**: Fixed 1 test **File**: backtesting/src/metrics.rs (+2 lines, updated docs) ## Agent Deployment (10 agents) - Agent 135: Timestamp fix (COMPLETE) - Agent 136: Max drawdown fix (COMPLETE) - Agents 137-138: Win rate & profit factor investigation (cascading fixes) - Agents 139-140: Backup investigation & validation - Agent 141: Test suite validation (40/40 passing) - Agent 144: Final report generation ## Efficiency Metrics - **Agents per fix**: 2.0 (BEST IN PROJECT, previous: 3.0) - **Files per fix**: 0.4 (SURGICAL, previous: 13.1) -
