## Phase 3: Verification (Agents 11-12) 

**Agent 11 - Coverage Verification**:
- Measured full workspace coverage: **37.83%** (not 47.03%)

- True baseline includes trading_engine (25,190 lines)

**Agent 12 - Resource Monitoring**:
- 30-45 minute monitoring, all systems healthy
- No cleanup actions needed

## Critical Discovery: Accurate Baseline Established

**Wave 115 Claim**: 47.03% coverage (incomplete - only 3 packages)
**Wave 116 Reality**: 37.83% coverage (full workspace measurement)

**Unmeasured Areas**:
- Compliance: 4,621 lines (0% coverage)
- Persistence: 2,735 lines (0% coverage)
- Config: 1,342 lines (0% coverage)
- Total 0% areas: 8,698 lines

## Test Quality Standards 

- NO empty tests or stubs
- ALL tests validate actual outputs
- Edge cases comprehensively tested
- Error paths validated
- Formula validation (Sharpe, Kelly, VaR, Bellman)
- 3-5 assertions per test average

## Files Changed

## Path Forward

**Current**: 37.83% coverage (accurate baseline)
**Target**: 60-70% coverage
**Timeline**: 4-6 weeks (target zero coverage areas)

**Wave 117 Priorities**:
1. Fix 1 test failure (Redis connection)
2. Zero coverage areas: +8,600 lines → +13-15% coverage
3. Service coverage measurement (SQLx unblocked)
4. ML/backtesting compilation (resolve timeout)

Backtesting Service

Overview

The backtesting_service offers an independent and isolated environment for rigorously testing and validating trading strategies against historical market data. It provides a robust platform for simulating trading performance, analyzing strategy efficacy, and generating comprehensive performance reports before live deployment.

Features

  • Independent Backtesting Service: Operates autonomously, allowing for parallel and isolated strategy evaluations.
  • gRPC API for Backtest Execution: Exposes a clear API for submitting and managing backtesting jobs.
  • Strategy Testing and Validation: Enables comprehensive testing of various trading strategies under different market conditions.
  • Performance Reporting: Generates detailed reports including metrics like P&L, Sharpe ratio, drawdown, and win rate.
  • Data Replay Engine: Accurately replays historical market data, simulating real-world order book dynamics and trade execution.
  • Results Persistence: Stores backtesting results and reports for historical analysis and comparison.

gRPC API

The backtesting_service exposes a gRPC API for initiating and retrieving backtest results. Key endpoints include:

  • RunBacktest - Submit backtest configuration and strategy
  • GetBacktestResults - Retrieve results for completed backtests
  • ListAvailableStrategies - List registered strategies
  • GetBacktestReport - Get detailed performance report

Running the service

To run the backtesting_service binary:

cargo run --bin backtesting_service

Data Requirements

The service requires historical market data in Parquet format:

  • Data should be stored in the configured data directory
  • Supports tick data, order book snapshots, and OHLCV candles
  • Data must include instrument, timestamp, and price/quantity fields

Testing

To run the tests for the backtesting_service crate:

cargo test --package backtesting_service

Documentation

Comprehensive API documentation is available at docs.rs/backtesting_service.
