-## Reporting Issues
+### 2. Create a Branch
 
-If you encounter any issues or have suggestions for improvements, please open an issue on GitHub.
+```bash
+# Use conventional commit prefixes in branch names
+git checkout -b feat/your-feature-name
+# or
+git checkout -b fix/bug-description
+git checkout -b docs/documentation-update
+git checkout -b refactor/code-cleanup
+```
 
-## Guidelines
+**Branch naming convention:**
+- `feat/` - New features
+- `fix/` - Bug fixes
+- `docs/` - Documentation changes
+- `refactor/` - Code refactoring
+- `test/` - Test additions/fixes
+- `chore/` - Maintenance tasks
 
-- Ensure your code follows the project's coding standards.
-- Write clear and concise commit messages.
-- Update documentation as needed.
-- Test your changes thoroughly before submitting a pull request.
+### 3. Make Your Changes
 
-Thank you for contributing to Predix!
+Follow the project conventions:
+
+- **Code style**: Use type hints, docstrings (Google style), and 120 char line limit
+- **Language**: All comments and documentation MUST be in English
+- **Structure**: Follow the existing module structure
+
+### 4. Write Tests
+
+**MANDATORY:** All new features MUST have tests with >80% coverage.
+
+```bash
+# Run tests
+pytest test/ -v
+
+# Run with coverage
+pytest --cov=rdagent --cov-report=html
+
+# Run integration tests
+pytest test/integration/ -v
+```
+
+### 5. Run Pre-commit Hooks
+
+Pre-commit hooks run automatically before EVERY commit:
+
+```bash
+# Install pre-commit
+pre-commit install
+
+# Run manually
+pre-commit run --all-files
+```
+
+### 6. Commit Your Changes
+
+Use [Conventional Commits](https://www.conventionalcommits.org/) format:
+
+```bash
+git commit -m "type: description"
+
+# Types:
+# feat:     New feature
+# fix:      Bug fix
+# docs:     Documentation
+# style:    Formatting
+# refactor: Code restructuring
+# test:     Tests
+# chore:    Maintenance
+```
+
+**Examples:**
+```bash
+git commit -m "feat: Add Optuna hyperparameter optimization"
+git commit -m "fix: Resolve database connection timeout"
+git commit -m "docs: Update README with new CLI commands"
+git commit -m "test: Add integration tests for portfolio optimizer"
+```
+
+### 7. Push and Create a Pull Request
+
+```bash
+git push origin your-branch-name
+```
+
+Then open a Pull Request on GitHub with:
+- Clear title (use conventional commit format)
+- Description of changes
+- Link to related issues
+- Screenshots (for UI changes)
+
+## Code Review Process
+
+All PRs are reviewed by maintainers. Expect:
+- Automated checks (tests, linting, security scan)
+- Code review by maintainers
+- Possible requested changes
+
+## Important Rules
+
+### 🚫 NEVER COMMIT
+
+- `.env` files or API keys
+- Generated data (`results/`, `*.db`, `*.log`)
+- Closed-source assets (`models/local/`, `prompts/local/`)
+- JSON strategy files in root directory
+- Private credentials or tokens
+
+### ✅ ALWAYS DO
+
+- Write tests for new features
+- Update documentation for user-visible changes
+- Run `pre-commit run --all-files` before pushing
+- Keep commit messages in English
+- Follow conventional commit format

 ## Installation
 
+### System Requirements
+
+| Component | Minimum | Recommended |
+|-----------|---------|-------------|
+| **GPU VRAM** | 8 GB | 16 GB (RTX 4080 / 5060 Ti) |
+| **RAM** | 16 GB | 32 GB |
+| **Storage** | 20 GB | 50 GB (models + data) |
+| **OS** | Linux (Ubuntu 22.04+) | Linux |
+| **CUDA** | 12.0+ | 12.4+ |
+
+> Local LLMs require a CUDA-capable GPU. The default model (Qwen3.6-35B Q3) uses ~13.6 GB VRAM. CPU-only inference is possible but very slow (not recommended for production use).
+
 ### Prerequisites
 
-- **Python 3.10 or 3.11**
-- **Docker** (required for sandboxed code execution)
-- **Linux** (officially supported; macOS/Windows may work with adjustments)
+- **Conda** (Miniconda or Anaconda) — required for environment management
+- **Docker** — required for sandboxed factor/model code execution (`docker run hello-world` to verify)
+- **llama.cpp** — for local LLM inference (see [llama.cpp build guide](https://github.com/ggml-org/llama.cpp))
+- **Ollama** — for embeddings (`nomic-embed-text`); install from [ollama.com](https://ollama.com) and run `ollama pull nomic-embed-text`
+- **Linux** — officially supported; macOS/Windows may work with adjustments
 
 ### Quick Install
 
 ```bash
 # Clone repository
-git clone https://github.com/TPTBusiness/Predix
-cd predix
+git clone https://github.com/TPTBusiness/NexQuant
+cd NexQuant
 
-# Create conda environment
-conda create -n predix python=3.10
-conda activate predix
+# Create and activate conda environment
+conda create -n nexquant python=3.10 -y
+conda activate nexquant
 
 # Install in editable mode
-pip install -e .[test,lint]
+pip install -e .
+
+# Verify Docker is accessible
+docker run --rm hello-world
 ```
 
-### Configuration
+> **Important:** NexQuant requires a conda environment to manage dependencies properly.
+> Using plain Python or other environment managers may cause conflicts.
+
+---
+
+## Data Setup
+
+NexQuant requires **1-minute EUR/USD OHLCV data** in HDF5 format. This is a hard prerequisite — the system cannot run without it.
+
+### Step 1: Get the data
+
+Download 1-minute EUR/USD data (2020–present) from any of these free sources:
+
+| Source | Cost | Notes |
+|--------|------|-------|
+| **[Dukascopy](https://www.dukascopy.com/swiss/english/marketfeed/historical/)** | Free | Best quality free EUR/USD tick data |
+| **[OANDA API](https://developer.oanda.com/)** | Free (demo) | Requires API key, programmatic access |
+| **[TrueFX](https://truefx.com/)** | Free | Institutional-quality tick data |
+| **[Kaggle](https://www.kaggle.com/datasets?search=EURUSD+1min)** | Free | Search "EURUSD 1 minute" |
+| **MetaTrader 5** | Free | Export via `copy_rates_range()` |
+
+### Step 2: Convert to HDF5
+
+```python
+import pandas as pd
+
+df = pd.read_csv('eurusd_1min.csv', parse_dates=['datetime'])
+df = df.rename(columns={'open': '$open', 'close': '$close',
+                        'high': '$high', 'low': '$low', 'volume': '$volume'})
+df['instrument'] = 'EURUSD'
+df = df.set_index(['datetime', 'instrument'])
+for col in ['$open', '$close', '$high', '$low', '$volume']:
+    df[col] = df[col].astype('float32')
+
+import os
+os.makedirs('git_ignore_folder/factor_implementation_source_data', exist_ok=True)
+df.to_hdf('git_ignore_folder/factor_implementation_source_data/intraday_pv.h5', key='data', mode='w')
+```
+
+### Required HDF5 format
+
+| Field | Type | Description |
+|-------|------|-------------|
+| **Index** | MultiIndex `(datetime, instrument)` | Timestamp + currency pair |
+| **`$open`** | float32 | Open price |
+| **`$close`** | float32 | Close price |
+| **`$high`** | float32 | High price |
+| **`$low`** | float32 | Low price |
+| **`$volume`** | float32 | Tick volume |

+## No GPU? Use OpenRouter
+
+If you don't have a CUDA-capable GPU, you can run NexQuant using [OpenRouter](https://openrouter.ai) for LLM inference — no local model download required.
+
+**1. Set up `.env` for OpenRouter:**
+
+```bash
+# Chat (OpenRouter)
+OPENAI_API_KEY=sk-or-v1-<your-openrouter-key>
+OPENAI_API_BASE=https://openrouter.ai/api/v1
+CHAT_MODEL=qwen/qwen3-235b-a22b
+
+# Embedding (Ollama — still required locally)
+LITELLM_PROXY_API_KEY=local
+LITELLM_PROXY_API_BASE=http://localhost:11434/v1
+EMBEDDING_MODEL=nomic-embed-text
+```
+
+**2. Skip the llama-server step** — no local LLM server needed.
+
+**3. Run with the OpenRouter backend:**
+
+```bash
+rdagent fin_quant --model openrouter
+```
+
+**4. Parallel runs** (uses API concurrency instead of GPU slots):
+
+```bash
+python scripts/nexquant_parallel.py --runs 5 --api-keys 1 -m openrouter
+```
+
+> Ollama is still required for embeddings even in the OpenRouter path. Install from [ollama.com](https://ollama.com) and run `ollama pull nomic-embed-text` once.

+### 🤖 Kronos Foundation Model Integration
+
+NexQuant integrates Kronos — an OHLCV foundation model from the NeoQuasar team (AAAI 2026, **MIT License**) — for alpha factor generation:
+
+| Model | Params | p24 IC | Best For |
+|-------|--------|--------|----------|
+| **Kronos-small** (default) | 25M | \|IC\| ≈ 0.09 | 1-min EUR/USD |
+| Kronos-mini | 4.1M | \|IC\| ≈ 0.07 | Low-resource |
+| Kronos-base | 102M | \|IC\| ≈ 0.002 | Daily/weekly data only |
+
+Kronos generates 3 prediction-horizon factors automatically on `fin_quant` startup:
+- `KronosPredReturn_p24` — 24-minute horizon
+- `KronosPredReturn_p48` — 48-minute horizon  
+- `KronosPredReturn_p96` — 96-minute horizon (best performer)
+
+The model runs on GPU (CUDA) alongside the llama-server, using CPU as fallback.
+Factors are persisted in `results/factors/` for use by the strategy orchestrator.
+
+```bash
+# Kronos runs automatically with fin_quant (no separate command needed)
+rdagent fin_quant --loop-n 10 --model local
+
+# Model size is auto-detected and configurable via env
+# Set KRONOS_MODEL_SIZE=base to use the 102M-param model
+```
+
 ### 🔒 Security & Quality
 
 Automated quality assurance:
 
-- **60 Integration Tests** - All features tested automatically
-- **Bandit Security Scanner** - Pre-commit security checks
-- **Pre-commit Hooks** - Tests run before EVERY commit
+- **1,125+ collected tests** — deep property-based, fuzzing, and hypothesis tests on every commit

-
-```bash
-# Run the data setup script (if provided)
-./setup_predix_eurusd.sh
-
-# Or manually place data in:
-# ~/.qlib/qlib_data/eurusd_1min_data/
-```
-
-Expected data columns: `$open`, `$close`, `$high`, `$low`, `$volume`
-

+## Backtest Integrity
+
+Every backtest result is automatically verified at runtime against 10 mathematical invariants.  
+The verifier runs in **<1ms** and catches corrupted/missing/flipped metrics before they enter the factor database.
+
+### Runtime checks (every backtest)
+| Check | Constraint |
+|-------|-----------|
+| Max Drawdown | `-1.0 ≤ mdd ≤ 0.0` |
+| Win Rate | `0.0 ≤ wr ≤ 1.0` |
+| Sharpe Ratio | `sharpe` must be finite |
+| Total Return | `total_return` must be finite |
+| Trade Count | `n_trades ≥ 0` |
+| Sign consistency | `sign(sharpe) == sign(annual_return)` |
+| Status | Must be `success` or `failed` |
+
+### Test suite (CI + pre-commit)
+```bash
+pytest test/ -q        # 1,125+ collected, property-based + fuzzing
+pytest test/backtesting/ -q # backtest engine deep tests
+```
+
+**Coverage**: IC linear invariance, forward-return alignment, cross-implementation validation, ground-truth hand-computed scenarios, look-ahead bias detection, edge cases (all-NaN, constant, zero-variance, 1-bar, empty series), Monte Carlo p-value, walk-forward rolling, buy-and-hold equality, property-based testing (hypothesis: cost monotonicity, signal inversion, max-DD invariants), fuzzing (1,000 random backtest results), autopilot failure recovery, threshold rescaling, API key distribution, ML model acceptance criteria.

+# NexQuant v2.0.0 Release Notes
+
+**Release Date:** 2026-04-10
+
+**Tag:** v2.0.0
+
+---
+
+## 🎉 Overview
+
+Major update adding AI-powered strategy generation, realistic backtesting, and comprehensive CLI tooling. NexQuant now autonomously generates, evaluates, and optimizes trading strategies using local LLMs.
+
+---
+
+## ✨ Added
+
+### LLM-Powered Strategy Generation
+- **StrategyOrchestrator**: Generate trading strategies by combining factors with LLM
+- **Local llama.cpp Support**: Run strategy generation locally (Qwen3.5-35B)
+- **OpenRouter Support**: Optional cloud model fallback
+- **Improved Prompts (v3)**: IC-sign-aware factor combination instructions
+- **Diverse Factor Selection**: Automatic selection by type (momentum, divergence, volatility, session)
+
+### Realistic Backtesting
+- **OHLCV-Based Returns**: Real price returns instead of factor proxies
+- **Spread Costs**: 1.5 bps per trade deducted from returns
+- **Forward-Fill Support**: Daily factors → 1-min frequency
+- **Proper Annualization**: sqrt(252*1440) for 1-min data
+
+### CLI Commands
+- `rdagent nexquant` - Show beautiful welcome screen (perfect for screenshots!)
+- `rdagent start_llama` - Start llama.cpp server
+- `rdagent start_loop` - Start strategy generator loop with auto-restart

+# 🎯 PREDIX: Vollständige Integration in fin_quant Loop
+
+## ✅ Implementierte Features
+
+### 1. Realistisches Backtesting
+- **Echte OHLCV-Daten** aus `intraday_pv.h5` (2.26M Bars, 2020-2026)
+- **Forward-Fill** täglicher Faktoren auf 1-Min-Frequenz
+- **Spread-Kosten**: 1.5 bps pro Trade
+- **Korrekte Annualisierung**: sqrt(252*1440) für 1-Min-Daten
+
+### 2. Verbesserter LLM-Prompt
+- **IC-geführte Faktorwahl**: |IC| > 0.10 PRIORITIZE, |IC| > 0.05 USE
+- **IC-gewichtete Kombinationen**: Höhere IC = höheres Gewicht
+- **Bessere Beispiele** mit IC-Gewichten im Prompt
+- **Verfügbarkeit von 'close' Series** für zusätzliche Berechnungen
+
+### 3. Optuna-Optimierung
+- **20 Trials pro Strategie** (konfigurierbar)
+- **TPESampler** mit MedianPruner
+- **Optimiert**: entry_threshold, rolling_window, SL, TP, Trailing Stop
+- **Auto-Update** wenn Optuna Sharpe verbessert
+
+### 4. Automatische Strategiegenerierung
+- **Trigger**: Alle 500 Faktoren (konfigurierbar)
+- **3 Strategien pro Zyklus** mit zufälligen Faktor-Kombinationen
+- **Graceful Degradation**: Bricht Hauptloop nicht bei Fehlern
+
+## 🚀 Benutzung
+
+### Automatisch (im fin_quant Loop)
+```bash
+# Standard: Alle 500 Faktoren
+rdagent fin_quant --auto-strategies
+
+# Custom threshold
+rdagent fin_quant --auto-strategies --auto-strategies-threshold 1000
+
+# Mit OpenRouter
+rdagent fin_quant -m openrouter --auto-strategies
+```
+
+### Manuell
+```bash
+# 5 Strategien mit Optuna
+rdagent generate_strategies --count 5 --optuna --optuna-trials 20
+
+# Ohne Optuna (schneller)
+rdagent generate_strategies --count 5 --no-optuna
+```
+
+## 📊 Testergebnisse
+
+### MomentumDivergenceZScore (vorher vs. nachher)
+
+| Metrik | Vorher | Nachher |
+|--------|--------|---------|
+| **Datenpunkte** | 259 (4.3h) | 823,450 (2.27 Jahre) |
+| **Sharpe** | 3.59 | 6.04 |
+| **Max DD** | -0.22% | -1.57% |
+| **Win Rate** | 49.46% | 49.19% |
+| **Ann Return** | 543% (falsch) | 21.88% ✅ |
+
+## 🔧 Architecture
+
+```
+fin_quant Loop
+    │
+    ├─ Factor Generation (LLM → Docker → Evaluation)
+    │   └─ Every 500 factors → Trigger Strategy Generation
+    │
+    └─ StrategyOrchestrator (auto-strategies)
+        │
+        ├─ Load Top 50 Factors (by IC)
+        ├─ For each strategy (3x):
+        │   ├─ Select random 2-5 factors
+        │   ├─ LLM generates code (improved prompt)
+        │   ├─ Evaluate with real OHLCV
+        │   ├─ Optuna optimize (20 trials)
+        │   └─ Save if accepted
+        │
+        └─ Log results
+```
+
+## 📝 Nächste Schritte
+
+1. **Live Trading**: Bestehende Strategien für Paper Trading nutzen
+2. **Mehr Faktoren**: Weiterhin Faktoren generieren für bessere Strategien
+3. **Dashboard**: Live-Statistiken im Web/CLI Dashboard anzeigen
+
+## ⚠️ Wichtige Hinweise
+
+- **Forward-Fill** kann zu Daten-Leakage führen (tägliche Werte werden auf Minuten aufgefüllt)
+- **Optuna** benötigt 20-30 Sekunden pro Strategie
+- **Auto-Strategies** nur wenn ≥10 Faktoren verfügbar
+- **LLM** muss verfügbar sein (local oder openrouter)

+Beispiel 01: Factor Discovery - Automatische Faktor-Generierung
+
+Was macht dieses Beispiel?
+    Dieses Skript demonstriert die automatische Generierung neuer Trading-Faktoren
+    mittels LLM (Large Language Model). Es führt den CoSTEER-Loop aus, der:
+    1. Faktor-Hypothesen generiert
+    2. Implementiert und backtestet
+    3. Feedback für Verbesserungen gibt
+
+Voraussetzungen:
+    - PREDIX installiert (`pip install -e ".[all]"`)
+    - EURUSD 1-Minute Daten in Qlib geladen
+    - LLM-Server läuft (für --llm local) ODER API-Key gesetzt
+
+Erwartete Laufzeit:
+    ~10-15 Minuten pro Loop (local LLM)
+    ~30-60 Minuten pro Loop (API LLM)
+
+Output:
+    - Generierte Faktoren in RD-Agent_workspace/
+    - Performance-Metriken (ARR, Sharpe, IC, MaxDD)
+    - Faktor-Implementierungen als Python-Code

+Beispiel 06: RL Trading Agent - Reinforcement Learning für Trading
+
+Was macht dieses Beispiel?
+    Dieses Skript trainiert einen Reinforcement Learning (RL) Agent, der
+    eigenständig Trading-Entscheidungen trifft. Der Agent lernt durch
+    Trial-and-Error, wann er Long/Short gehen oder neutral bleiben soll.
+    
+    Unterstützte Algorithmen:
+    - PPO (Proximal Policy Optimization): Stabil, guter Default
+    - DQN (Deep Q-Network): Sample-effizient, aber komplexer
+    - A2C (Advantage Actor-Critic): Schneller, aber weniger stabil
+
+Voraussetzungen:
+    - RL-Abhängigkeiten installiert (`pip install -e ".[rl]"`)
+    - Faktor-Daten vorhanden (aus Beispiel 01)
+    - Empfohlen: GPU für schnellere Laufzeit
+
+Erwartete Laufzeit:
+    ~30-60 Minuten (CPU, 1000 Episodes)
+    ~10-20 Minuten (GPU, 1000 Episodes)
+
+Output:
+    - Trainierter RL-Agent in models/rl_agent/
+    - Learning Curve (Reward pro Episode)
+    - Trading-Statistiken des Agents

+python examples/01_factor_discovery.py --loop-n 5 --llm local
+```
+
+**Output:**
+- Generierte Faktoren in `RD-Agent_workspace/`
+- Performance-Metriken (ARR, Sharpe, IC)
+- Faktor-Implementierungen als Python-Code
+
+**Nächste Schritte:**
+→ Siehe `02_factor_evolution.py` um Faktoren zu optimieren
+
+### Beispiel 02: Factor Evolution
+
+**Ziel:** Bestehende Faktoren mit Session/Regime Filters verbessern
+
+```bash
+python examples/02_factor_evolution.py --factor momentum_16 --improve session_filter
+```
+
+**Output:**
+- Verbesserte Faktoren mit Before/After-Vergleich
+- Metrik-Verbesserungen (ARR +X%, Sharpe +X.X)
+
+### Beispiel 03: Strategy Generation
+
+**Ziel:** Mehrere Faktoren zu einer robusten Strategie kombinieren
+
+```bash
+python examples/03_strategy_generation.py --factors momentum_16,reversal,session_alpha
+```
+
+**Output:**
+- IC-weighted Faktor-Kombination
+- Signal-Verteilung (Long/Short/Neutral)
+
+### Beispiel 04: Backtest
+
+**Ziel:** Backtest einer Trading-Strategie auf historischen Daten
+
+```bash
+python examples/04_backtest_simple.py --strategy momentum --start 2020-01-01 --end 2025-12-31
+```
+
+**Output:**
+- Key-Metriken: ARR, Sharpe, MaxDD, WinRate
+- Equity Curve (optional als Plot)
+
+### Beispiel 05: Model Training
+
+**Ziel:** ML-Modell (LSTM/XGBoost) auf Faktor-Daten trainieren
+
+```bash
+python examples/05_model_training.py --model lstm --features momentum_16,reversal
+```
+
+**Output:**
+- Trainiertes Modell in `models/`
+- Train/Val/Test Split Ergebnisse
+- Feature Importance (bei XGBoost)
+
+### Beispiel 06: RL Trading Agent
+
+**Ziel:** Reinforcement Learning Agent für Trading trainieren
+
+```bash
+python examples/06_rl_trading_agent.py --algo ppo --episodes 1000
+```
+
+**Output:**
+- Trainierter RL-Agent in `models/rl_agent/`
+- Learning Curve
+- Trading-Statistiken

+    You are a CODE GENERATOR for quantitative trading strategies. You are NOT a chat assistant.
+
+    CRITICAL RULES - READ CAREFULLY:
+    1. You are a CODE GENERATOR, NOT a chat assistant.
+    2. NEVER greet the user, NEVER ask questions, NEVER say "Hello" or "How can I help".
+    3. ONLY output a valid JSON object. NOTHING else. No markdown, no explanation, no text before or after the JSON.
+    4. Your entire response MUST be parseable by json.loads() in Python.
+    5. The JSON must have exactly these fields: "strategy_name", "factors_used", "description", "code"
+    6. The "code" field must contain executable Python code as a SINGLE STRING (use \n for newlines).
+    7. DO NOT wrap the code in markdown code blocks (no ```python ... ```).
+    8. DO NOT define functions with def - write DIRECT EXECUTABLE CODE that creates a 'signal' variable.
+
+    If you output ANY text other than a valid JSON object, the system will REJECT your response and retry.
+    Your ONLY job is to output JSON. Nothing else.

+    Task: Generate a trading strategy by combining the provided EUR/USD factors.
+
+    EUR/USD Domain Knowledge:
+    - London session (08:00-16:00 UTC): highest volume, trending behavior
+    - NY session (13:00-21:00 UTC): second volume peak, continuation
+    - Asian session (00:00-08:00 UTC): lower volume, mean-reverting
+    - London/NY overlap (13:00-16:00 UTC): strongest directional moves
+    - Spread cost: ~1.5 bps per trade - signals must overcome this
+
+    Factor Usage Rules:
+    1. ONLY use the factors provided below - no others!
+    2. The code will execute with a DataFrame called 'factors' and a Series called 'close'
+    3. You MUST create a pandas Series called 'signal' with values: 1 (long), -1 (short), 0 (neutral)
+    4. signal.index MUST match factors.index exactly
+    5. signal.name must be 'signal'
+
+    IC-Guided Factor Selection:
+    - Factors with |IC| > 0.10 are highly predictive - PRIORITIZE these
+    - Factors with |IC| > 0.05 are moderately predictive - USE these
+    - Factors with |IC| < 0.05 are weak - AVOID unless complementary
+    - Combine factors with different signs of IC for diversification
+    - Weight factors proportionally to their |IC| values
+
+    IMPORTANT: Understanding IC Sign
+    - Factors with POSITIVE IC (e.g., IC=+0.25): HIGH factor value means price goes UP - go LONG
+    - Factors with NEGATIVE IC (e.g., IC=-0.20): HIGH factor value means price goes DOWN - go SHORT
+    - Best strategies COMBINE both types: use positive IC for trend, negative IC for divergence
+
+    Signal Quality Requirements:
+    - Generate balanced signals (40-60% in each direction)
+    - Use rolling z-scores: (x - rolling.mean()) / rolling.std()
+    - Apply thresholds based on signal distribution (e.g., z > 0.5 for long, z < -0.5 for short)
+    - Combine factors respecting their IC SIGN (multiply negative IC factors by -1)
+    - Consider regime filters (trend vs mean-reversion)
+
+  user: |
+    Generate a EUR/USD trading strategy using these factors:
+
+    {{ factors }}
+
+    {{ additional_context }}
+
+    TRADING STYLE: {{ trading_style }}
+    TARGET SHARPE: > {{ min_sharpe }}
+    MAX DRAWDOWN: {{ max_drawdown }}
+
+    CRITICAL CODE RULES:
+    1. DO NOT define functions - write direct executable code
+    2. DO NOT use 'def' - just write code that creates 'signal'
+    3. The code runs with 'factors' DataFrame and 'close' Series already in scope
+    4. You MUST create a variable called 'signal' as a pandas Series
+    5. signal must have values 1 (LONG), -1 (SHORT), or 0 (NEUTRAL)
+    6. signal.index must equal factors.index
+    7. RESPECT IC SIGN: Negative IC factors should be INVERTED (multiplied by -1)
+
+    ---
+
+    CORRECT OUTPUT FORMAT (EXACTLY THIS - JSON ONLY):
+
+    {"strategy_name": "MomentumDivergence_v1", "factors_used": ["daily_close_return_96", "daily_session_momentum_divergence_1d"], "description": "Combines positive IC momentum with inverted negative IC divergence using rolling z-scores.", "code": "import pandas as pd\nimport numpy as np\n\nmom = factors['daily_close_return_96']\ndiv = factors['daily_session_momentum_divergence_1d']\n\nz_mom = (mom - mom.rolling(20).mean()) / mom.rolling(20).std()\nz_div = -(div - div.rolling(20).mean()) / div.rolling(20).std()\n\ncomposite = 0.56 * z_mom + 0.44 * z_div\nsignal = pd.Series(0, index=factors.index)\nsignal[composite > 0.5] = 1\nsignal[composite < -0.5] = -1\nsignal.name = 'signal'"}

+    - "```python\n...\n```" (NO MARKDOWN BLOCKS)
+    - "def generate_signal(...)" (NO FUNCTION DEFINITIONS)
