+- `scipy` - For statistical functions (VaR, calibration)
+- `hmmlearn` - For HMM regime detection (optional)
+- `shap` - For model explainability (optional)
+- `scikit-optimize` - For Bayesian optimization (optional)
+
+All features have graceful degradation if optional dependencies are not available.
+
+## Usage Examples
+
+### VaR Calculation
+```python
+from src.risk.var_calculator import get_var_calculator
+
+var_calc = get_var_calculator()
+results = await var_calc.calculate_all_var_methods(
+    portfolio_value=Decimal("10000.0"),
+    confidence_level=0.95,
+    holding_period_days=1
+)
+```
+
+### Monte Carlo Backtesting
+```python
+from src.backtesting.monte_carlo import MonteCarloSimulator
+from src.backtesting.engine import BacktestingEngine
+
+engine = BacktestingEngine()
+simulator = MonteCarloSimulator(engine)
+results = await simulator.run_monte_carlo(
+    strategy_class=MyStrategy,
+    symbol="BTC/USD",
+    exchange="coinbase",
+    timeframe="1h",
+    start_date=start,
+    end_date=end,
+    num_simulations=1000
+)
+```
+
+### Online Learning
+```python
+from src.autopilot.online_learning import get_online_learning_pipeline
+
+pipeline = get_online_learning_pipeline(model)
+await pipeline.add_training_sample(
+    market_conditions=conditions,
+    strategy_name="strategy_name",
+    performance=0.05
+)
+```
+
+### Confidence Calibration
+```python
+from src.autopilot.confidence_calibration import get_confidence_calibration_manager
+
+calibrator = get_confidence_calibration_manager()
+strategy, calibrated_conf, calibrated_preds = calibrator.calibrate_prediction(
+    strategy_name="strategy",
+    confidence=0.85,
+    all_predictions={...}
+)
+```
+
+### Model Explainability
+```python
+from src.autopilot.explainability import get_model_explainer
+
+explainer = get_model_explainer(model)
+explanation = explainer.explain_prediction(features)
+```
+
+## Configuration
+
+Key configuration options added/updated in `config/config.yaml`:
+
+```yaml
+autopilot:
+  intelligent:
+    bootstrap:
+      days: 365  # Increased from 5
+      timeframe: "1h"
+      min_samples_per_strategy: 10
+    online_learning:
+      drift_window: 100
+      drift_threshold: 0.1
+      buffer_size: 50
+      update_frequency: 100
+
+risk:
+  var:
+    default_confidence: 0.95
+    default_holding_period_days: 1
+    lookback_days: 252
+```
+

+
+**Features**:
+- Hidden Markov Models (HMM) for regime detection
+- Gaussian Mixture Models (GMM) for regime detection
+- Hybrid detection combining multiple methods
+- Probabilistic regime predictions
+
+**Methods**:
+- `HMM`: Models regime transitions as Markov process

+- `Hybrid`: Combines both methods for robust detection
+
+**Usage**:
+```python
+from src.autopilot.regime_detection import AdvancedRegimeDetector
+
+detector = AdvancedRegimeDetector(method="hmm")
+detector.fit_from_dataframe(ohlcv_df)
+
+regime = detector.detect_regime(returns=0.01, volatility=0.02)

+2. **Confidence Calibration**: Applied in `select_best_strategy` method
+3. **Explainability**: Available via API endpoints for UI visualization
+4. **Regime Detection**: Used in `MarketAnalyzer` for enhanced regime classification
+
+## Configuration
+
+Configuration options in `config/config.yaml`:
+
+```yaml
+autopilot:
+  intelligent:
+    online_learning:
+      drift_window: 100
+      drift_threshold: 0.1
+      buffer_size: 50
+      update_frequency: 100
+    confidence_calibration:
+      method: "isotonic"  # or "platt"
+    regime_detection:
+      method: "hmm"  # or "gmm" or "hybrid"
+      n_regimes: 4
+```
+
+## Dependencies
+
+Optional dependencies (with fallbacks):
+- `hmmlearn`: For HMM regime detection
+- `shap`: For model explainability
+- `scipy`: For calibration methods (isotonic regression)
+
+## Performance Considerations
+
+- **Online Learning**: Batches updates for efficiency (configurable buffer size)
+- **SHAP Values**: Can be slow for large models; consider caching or background computation
+- **HMM/GMM**: Training is fast, prediction is very fast
+- **Calibration**: Fitting is fast, prediction is O(1)
+
+## Testing
+
+Recommended testing approach:
+1. Use synthetic data for online learning pipeline
+2. Test calibration with known probability distributions
+3. Validate SHAP values against known feature importance
+4. Compare HMM/GMM regimes against rule-based classification

 # Risk Management Architecture

+## Overview
+
+The risk management system provides comprehensive risk control mechanisms including position sizing, stop-loss management, drawdown limits, Value at Risk (VaR) calculation, and portfolio correlation analysis.
+
+## Components
+
+### Position Sizing
+
+**Location**: `src/risk/position_sizing.py`
+
+**Methods**:
+- **Standard Position Sizing**: Percentage-based with fee accounting
+- **Kelly Criterion**: Optimal position sizing with fractional Kelly (configurable)
+- **Volatility-Adjusted**: ATR-based position sizing (lower vol = larger positions)
+- **Regime-Aware**: Adjusts position size based on market regime
+- **Confidence-Based**: ML model confidence-adjusted position sizing
+
+**Usage**:
+```python
+from src.risk.position_sizing import PositionSizingManager
+
+sizer = PositionSizingManager()
+
+# Standard sizing
+quantity = sizer.calculate_size(symbol, price, balance, risk_percent)
+
+# Kelly Criterion (fractional)
+kelly_pct = sizer.calculate_kelly_criterion(win_rate=0.6, avg_win=100, avg_loss=50, fractional=0.25)
+
+# Volatility-adjusted
+quantity = sizer.calculate_volatility_adjusted_size(symbol, price, balance, volatility_multiplier=0.8)
+
+# Regime-aware
+quantity = sizer.calculate_regime_aware_size(symbol, price, balance, market_regime="trending_up")
+```
+
+### Value at Risk (VaR)
+
+**Location**: `src/risk/var_calculator.py`
+
+**Methods**:
+1. **Historical VaR**: Uses historical portfolio returns distribution
+2. **Parametric VaR**: Assumes normal distribution (variance-covariance method)
+3. **Monte Carlo VaR**: Simulates future returns using estimated parameters
+4. **Conditional VaR (CVaR)**: Expected loss given that loss exceeds VaR
+
+**Usage**:
+```python
+from src.risk.var_calculator import get_var_calculator
+
+var_calc = get_var_calculator()
+
+# Calculate all methods
+results = await var_calc.calculate_all_var_methods(
+    portfolio_value=Decimal("10000.0"),
+    confidence_level=0.95,
+    holding_period_days=1
+)
+
+# Individual methods
+historical_var = await var_calc.calculate_historical_var(...)
+parametric_var = await var_calc.calculate_parametric_var(...)
+monte_carlo_var = await var_calc.calculate_monte_carlo_var(...)
+cvar = await var_calc.calculate_cvar(...)
+```
+
+### Portfolio Correlation Analysis
+
+**Location**: `src/portfolio/correlation_analyzer.py`
+
+**Features**:
+- Correlation matrix calculation for portfolio symbols
+- Diversification scoring (lower correlation = better)
+- Concentration risk analysis
+- Correlation-based position limits
+
+**Usage**:
+```python
+from src.portfolio.correlation_analyzer import get_correlation_analyzer
+
+analyzer = get_correlation_analyzer()
+
+# Analyze current portfolio
+analysis = await analyzer.analyze_portfolio_correlation(paper_trading=True)
+
+# Check correlation limits before adding position
+allowed, reason = await analyzer.check_correlation_limits(
+    symbol="ETH/USD",
+    new_position_value=Decimal("1000.0"),
+    max_correlation=0.8
+)
+```
+

+## Advanced Backtesting Features
+
+### Walk-Forward Analysis
+
+Walk-forward analysis provides robust parameter optimization by using rolling windows:
+
+1. **Training Period**: Strategy parameters are optimized on training data (e.g., 90 days)
+2. **Testing Period**: Optimized parameters are tested on out-of-sample data (e.g., 30 days)
+3. **Rolling Window**: Window advances by step size (e.g., 30 days) and process repeats
+
+This method prevents overfitting and provides more realistic performance estimates than single-period optimization.
+
+**Benefits**:
+- Prevents overfitting to historical data
+- Tests strategy robustness across different market conditions
+- Provides confidence intervals for parameter estimates
+- Validates strategy performance on unseen data
+
+### Monte Carlo Simulation
+
+Monte Carlo simulation tests strategy robustness by running thousands of random scenarios:
+
+- **Random Parameter Variation**: Tests strategy performance across parameter ranges
+- **Statistical Analysis**: Provides distribution of returns, Sharpe ratios, and drawdowns
+- **Confidence Intervals**: Shows expected performance ranges (e.g., 95% confidence)
+- **Risk Assessment**: Identifies worst-case scenarios and tail risks
+
+Use Monte Carlo simulation to:
+- Validate strategy robustness
+- Assess parameter sensitivity
+- Understand potential downside risks
+- Estimate performance under various market conditions
+
 ## Parameter Optimization

-Parameter optimization allows you to automatically find the best strategy parameters. This feature requires backend API support and will be available once the optimization endpoints are implemented.
+Parameter optimization allows you to automatically find the best strategy parameters using multiple algorithms:

-The UI includes an information card explaining this feature. When available, you'll be able to:
+- **Grid Search**: Exhaustive search across parameter grid (best for small parameter spaces)
+- **Bayesian Optimization**: Efficient exploration using Gaussian process (best for expensive evaluations)
+- **Genetic Algorithms**: Evolutionary search that finds good solutions efficiently
+
+Optimization metrics include:
+- Sharpe Ratio (risk-adjusted returns)
+- Total Return
+- Maximum Drawdown
+- Win Rate
+
+When available via the backend API, you'll be able to:
 - Select parameters to optimize
 - Set parameter ranges
- Choose optimization method (Grid Search, Genetic Algorithm, Bayesian Optimization)
+- Choose optimization method
 - View optimization progress
 - Compare optimization results

+## Advanced Risk Management
+
+### Value at Risk (VaR)
+
+Crypto Trader provides comprehensive Value at Risk calculations using multiple methods:
+
+- **Historical VaR**: Based on historical portfolio return distribution
+- **Parametric VaR**: Assumes normal distribution (variance-covariance method)
+- **Monte Carlo VaR**: Simulates future returns using estimated parameters
+- **Conditional VaR (CVaR)**: Expected loss given that loss exceeds VaR threshold
+
+VaR helps quantify potential portfolio losses at specified confidence levels (e.g., 95% confidence, 1-day holding period).
+
+### Portfolio Correlation Analysis
+
+Monitor portfolio diversification and correlation risk:
+
+- **Correlation Matrix**: View correlation between all portfolio positions
+- **Diversification Score**: Measure how well-diversified your portfolio is
+- **Concentration Risk**: Identify over-concentration in correlated assets
+- **Correlation-based Limits**: Automatically prevent over-concentration
+
+Lower correlation between positions indicates better diversification and reduced portfolio risk.
+
+## Portfolio Rebalancing
+
+Automated portfolio rebalancing helps maintain your target asset allocation and can be triggered by:
+
+- **Threshold-based**: Rebalance when allocation drifts beyond specified threshold (e.g., 5% deviation)
+- **Time-based**: Rebalance at regular intervals (e.g., daily, weekly, monthly)
+- **Fee-aware**: Considers trading fees when determining if rebalancing is cost-effective
+
+Rebalancing automatically calculates required trades to restore target allocations while minimizing fees and market impact.
