Test Execution Guide

Quick Validation (Core Tests)

# Run core endpoint tests (no services required)
./scripts/validate_grpc_endpoints.sh

# Expected output:
# Total Tests:  6
# Passed:       6
# Failed:       0
# Pass Rate:    100%
# ✅ ALL TESTS PASSED

Full Integration Testing (Requires Services)

# Step 1: Start infrastructure
docker-compose up -d postgres redis vault

# Step 2: Start Trading Service
cargo run -p trading_service --release &
TRADING_PID=$!
sleep 8

# Step 3: Run regime detection tests

225-Feature Extraction Architecture

Feature Pipeline Flow

Market Data → Feature Extractor → 225-Feature Vector → ML Models
    ↓              ↓                       ↓                ↓
  DBN Bar    Wave C (201)          Regime Features    DQN/PPO/MAMBA/TFT
             Wave D (24)           (indices 201-224)

Feature Breakdown

Feature Set	Indices	Count	Description
Base OHLCV	0-17	18	Open, High, Low, Close, Volume, Returns
Wave A Indicators	18-25	8	RSI, MACD, Bollinger, ATR
Microstructure	26-67	42	Order flow, spreads, imbalances
Alternative Bars	68-95	28	Tick, volume, dollar, imbalance bars
Wave C Advanced	96-200	105	Statistical, fractal, regime features
Wave D CUSUM	201-210	10	Structural break detection
Wave D ADX	211-215	5	Directional indicators
Wave D Transitions	216-220	5	Regime transition probabilities
Wave D Adaptive	221-224	4	Adaptive strategy metrics
TOTAL	0-224	225	Complete feature set

Integration Points

1. Common Crate (ProductionFeatureExtractor225 trait)

   • Interface for 225-feature extraction
   • Used by all services via SharedMLStrategy

2. ML Crate (FeatureExtractor::extract_current_features())

   • Production implementation
   • Returns Tensor<[225]>

3. Trading Service (Real-time extraction)

   • Extracts features for each incoming order
   • Uses regime state for adaptive sizing

4. Backtesting Service (Historical replay)

   • Extracts features from DBN data
   • Validates strategy performance
