Agent 17 Quick Reference - ML Order Service Tests

✅ Completed

• Created 6 unit tests for ML order service (374 lines)
• Test file: services/trading_service/tests/ml_order_service_tests.rs

❌ Blocking Issue

File: services/trading_service/src/services/trading.rs:667 Problem: Calls non-existent method generate_prediction on EnsembleCoordinator Available: predict() method returns EnsembleDecision

🔧 Required Fix

// BEFORE (Line 667) ❌
ensemble_coordinator.generate_prediction(&req.symbol, &req.features).await

// AFTER ✅
// 1. Convert Vec<f64> to ml::Features
let features = ml::Features {
    values: req.features,
    names: vec!["open", "high", ...], // 26 feature names
    timestamp: chrono::Utc::now().timestamp_micros() as u64,
    symbol: Some(req.symbol.clone()),
};

// 2. Call predict() method
let decision = ensemble_coordinator.predict(&features).await?;

// 3. Convert TradingAction enum to String
let action = match decision.action {
    TradingAction::Buy => "BUY",
    TradingAction::Sell => "SELL",
    TradingAction::Hold => "HOLD",
}.to_string();

// 4. Store in database with generated UUID
let prediction_id = uuid::Uuid::new_v4();
// Insert into ensemble_predictions table...
