# XAUUSD Trading AI: A Machine Learning Approach Using Smart Money Concepts **Author: Jonus Nattapong Tapachom** **Date: September 18, 2025** ## Abstract This paper presents a comprehensive machine learning framework for predicting XAUUSD (Gold vs US Dollar) price movements using Smart Money Concepts (SMC) strategy elements. The proposed system achieves an 85.4% win rate in backtesting across six years of historical data (2015-2020), demonstrating the effectiveness of combining technical analysis with advanced machine learning techniques. The model utilizes XGBoost classification to predict 5-day ahead price direction, incorporating 23 features including traditional technical indicators (SMA, EMA, RSI, MACD, Bollinger Bands) and SMC-specific features (Fair Value Gaps, Order Blocks, Recovery patterns). The system addresses class imbalance through strategic weighting and achieves robust performance across different market conditions. **Keywords**: Algorithmic Trading, Machine Learning, Smart Money Concepts, XAUUSD, XGBoost, Technical Analysis ## 1. Introduction ### 1.1 Background Algorithmic trading has revolutionized financial markets, enabling systematic execution of trading strategies with speed and precision previously unattainable by human traders. The foreign exchange (FX) market, particularly currency pairs involving commodities like gold (XAUUSD), presents unique challenges due to its 24/5 operation and sensitivity to global economic events. Smart Money Concepts (SMC) represent a relatively new paradigm in technical analysis, focusing on identifying institutional trading patterns rather than retail-driven price action. SMC principles emphasize understanding market structure, liquidity concepts, and institutional order flow. ### 1.2 Problem Statement Traditional technical analysis indicators often fail to capture the sophisticated strategies employed by institutional traders. This research addresses the gap by developing a machine learning model that incorporates SMC principles alongside conventional technical indicators to predict short-term price movements in XAUUSD. ### 1.3 Research Objectives 1. Develop a comprehensive feature set combining SMC and technical indicators 2. Implement and optimize an XGBoost-based prediction model 3. Validate performance through rigorous backtesting 4. Analyze model robustness across different market conditions 5. Provide a reproducible framework for algorithmic trading research ### 1.4 Contributions - Novel integration of SMC concepts with machine learning - Comprehensive feature engineering methodology - Robust backtesting framework with yearly performance analysis - Open-source implementation for research community - Empirical validation of SMC effectiveness in algorithmic trading ## 2. Literature Review ### 2.1 Algorithmic Trading in FX Markets Research in algorithmic trading has evolved from simple rule-based systems to sophisticated machine learning approaches. Studies by Kearns and Nevmyvaka (2013) demonstrated that machine learning techniques can significantly outperform traditional technical analysis in forex markets. More recent work by Dixon et al. (2020) shows that deep learning models can capture complex market dynamics. ### 2.2 Smart Money Concepts SMC methodology, popularized by ICT (Inner Circle Trader) concepts, focuses on identifying institutional trading behavior through market structure analysis. Key SMC elements include: - **Order Blocks**: Areas where significant buying/selling occurred - **Fair Value Gaps**: Price imbalances between candles - **Liquidity Concepts**: Understanding where institutional orders are placed - **Market Structure**: Recognition of higher-timeframe trends ### 2.3 Machine Learning in Trading XGBoost has emerged as a powerful tool for financial prediction tasks. Chen and Guestrin (2016) demonstrated its effectiveness in various domains, including finance. Studies by Kraus and Feuerriegel (2017) show that gradient boosting methods outperform traditional statistical models in stock price prediction. ### 2.4 Gold Price Prediction XAUUSD presents unique characteristics as both a commodity and currency pair. Research by Baur and Lucey (2010) highlights gold's safe-haven properties during market stress. Studies by Pierdzioch et al. (2016) demonstrate that gold prices are influenced by multiple factors including interest rates, inflation expectations, and geopolitical events. ## 3. Methodology ### 3.1 Data Collection #### 3.1.1 Data Source Historical XAUUSD data was obtained from Yahoo Finance using the ticker symbol "GC=F" (Gold Futures). The dataset spans from January 2000 to December 2020, providing approximately 21 years of daily price data. #### 3.1.2 Data Preprocessing Raw data included Open, High, Low, Close prices and Volume. Preprocessing steps included: - Removal of missing values and outliers - Adjustment for corporate actions (minimal for futures) - Calculation of returns and volatility measures - Data quality validation ### 3.2 Feature Engineering #### 3.2.1 Technical Indicators Traditional technical indicators were calculated using the TA-Lib library: **Trend Indicators:** - Simple Moving Averages (SMA): 20-day and 50-day periods - Exponential Moving Averages (EMA): 12-day and 26-day periods **Momentum Indicators:** - Relative Strength Index (RSI): 14-day period - Moving Average Convergence Divergence (MACD): Standard parameters **Volatility Indicators:** - Bollinger Bands: 20-day period, 2 standard deviations #### 3.2.2 SMC Feature Implementation **Fair Value Gaps (FVG):** ```python def calculate_fvg(df): gaps = [] for i in range(1, len(df)-1): if df['Low'][i] > df['High'][i-1] and df['Low'][i] > df['High'][i+1]: # Bullish FVG gap_size = df['Low'][i] - max(df['High'][i-1], df['High'][i+1]) gaps.append({'type': 'bullish', 'size': gap_size, 'index': i}) elif df['High'][i] < df['Low'][i-1] and df['High'][i] < df['Low'][i+1]: # Bearish FVG gap_size = min(df['Low'][i-1], df['Low'][i+1]) - df['High'][i] gaps.append({'type': 'bearish', 'size': gap_size, 'index': i}) return gaps ``` **Order Blocks:** Order blocks were identified by analyzing significant price movements and volume spikes, representing areas where institutional accumulation or distribution occurred. **Recovery Patterns:** Implemented as pullbacks within trending markets, identifying potential continuation patterns. #### 3.2.3 Lag Features Price lag features were included to capture momentum and mean-reversion effects: - Close price lags: 1, 2, and 3 days - Return lags: 1, 2, and 3 days ### 3.3 Target Variable Construction The prediction target was defined as binary classification for 5-day ahead price direction: ``` Target = 1 if Close[t+5] > Close[t] else 0 ``` This represents whether the price will be higher or lower in 5 trading days. ### 3.4 Model Development #### 3.4.1 XGBoost Implementation XGBoost was selected for its proven performance in financial prediction tasks. Key hyperparameters were optimized through grid search: ```python model_params = { 'n_estimators': 200, 'max_depth': 7, 'learning_rate': 0.2, 'scale_pos_weight': 1.17, # Class balancing 'objective': 'binary:logistic', 'eval_metric': 'logloss' } ``` #### 3.4.2 Class Balancing Given the slight class imbalance (54% down, 46% up), scale_pos_weight was calculated as: ``` scale_pos_weight = negative_samples / positive_samples = 0.54 / 0.46 ≈ 1.17 ``` #### 3.4.3 Cross-Validation 3-fold time-series cross-validation was implemented to prevent data leakage while maintaining temporal order. ### 3.5 Backtesting Framework #### 3.5.1 Strategy Implementation A simple long/short strategy was implemented using Backtrader: - Long position when prediction = 1 (price expected to rise) - Short position when prediction = 0 (price expected to fall) - Fixed position sizing (no risk management implemented) #### 3.5.2 Performance Metrics - Win Rate: Percentage of profitable trades - Total Return: Cumulative portfolio return - Sharpe Ratio: Risk-adjusted return measure - Maximum Drawdown: Largest peak-to-trough decline ## 4.

Discussion ### 5.1 Position Sizing and Risk Management #### 5.1.1 Kelly Criterion Adaptation The position sizing incorporates a modified Kelly Criterion for optimal capital allocation: ``` Position Size = Account Balance × Risk Percentage × Win Rate Adjustment ``` Where: - **Account Balance**: Current portfolio value ($10,000 initial) - **Risk Percentage**: 1% per trade (conservative approach) - **Win Rate Adjustment**: √(Win Rate) for volatility scaling **Calculated Position Size**: $10,000 × 0.01 × √(0.854) ≈ $260 per trade #### 5.1.2 Kelly Fraction Formula ``` Kelly Fraction = (Win Rate × Odds) - Loss Rate ``` Where: - **Win Rate (p)**: 0.854 - **Odds (b)**: Average Win/Loss Ratio = 1.45 - **Loss Rate (q)**: 1 - p = 0.146 **Kelly Fraction**: (0.854 × 1.45) - 0.146 = 1.14 (adjusted to 20% for safety) ### 5.2 Risk-Adjusted Performance Metrics #### 5.2.1 Sharpe Ratio Calculation ``` Sharpe Ratio = (Rp - Rf) / σp ``` Where: - **Rp**: Portfolio return (18.2%) - **Rf**: Risk-free rate (0% for simplicity) - **σp**: Portfolio volatility (12.9%) **Result**: 18.2% / 12.9% = 1.41 #### 5.2.2 Sortino Ratio (Downside Deviation) ``` Sortino Ratio = (Rp - Rf) / σd ``` Where: - **σd**: Downside deviation (8.7%) **Result**: 18.2% / 8.7% = 2.09 #### 5.2.3 Maximum Drawdown Formula ``` MDD = max_{t∈[0,T]} (Peak_t - Value_t) / Peak_t ``` **2018 MDD Calculation**: - Peak Value: $10,000 (Jan 2018) - Trough Value: $9,130 (Dec 2018) - MDD: ($10,000 - $9,130) / $10,000 = 8.7% #### 5.2.4 Calmar Ratio ``` Calmar Ratio = Annual Return / Maximum Drawdown ``` **Result**: 3.0% / 8.7% = 0.34 (moderate risk-adjusted return) ### 5.3 Advanced SMC Implementation Techniques #### 5.3.1 Fair Value Gap Detection Algorithm ```python def advanced_fvg_detection(prices_df, volume_df, lookback=5): """ Advanced FVG detection with volume confirmation """ fvgs = [] for i in range(lookback, len(prices_df) -

0.05 # More aggressive else: adjusted_threshold = base_threshold # Recent performance adjustment if recent_performance > 0.6: adjusted_threshold -= 0.05 # More aggressive elif recent_performance < 0.4: adjusted_threshold += 0.1 # More conservative return max(0.3, min(0.8, adjusted_threshold)) # Bound between 0.3-0.8 ``` ### 5.4 Ensemble Signal Confirmation Framework ```python def ensemble_signal_confirmation(ml_prediction, technical_signals, smc_signals): """ Combine multiple signal sources for robust decision making """ # Weights for different signal sources ml_weight = 0.6 technical_weight = 0.25 smc_weight = 0.15 # Normalize signals to 0-1 scale ml_signal = ml_prediction['probability'] technical_signal = technical_signals['composite_score'] / 100 smc_signal = smc_signals['strength_score'] / 10 # Weighted ensemble ensemble_score = (ml_weight * ml_signal + technical_weight * technical_signal + smc_weight * smc_signal) # Confidence calculation based on signal variance signal_variance = calculate_signal_variance([ml_signal, technical_signal, smc_signal]) confidence = 1 / (1 + signal_variance) return { 'ensemble_score': ensemble_score, 'confidence': confidence, 'signal_strength': 'strong' if ensemble_score > 0.65 else 'moderate' if ensemble_score > 0.55 else 'weak' } ``` ## 6.
