This technical whitepaper presents a comprehensive algorithmic trading framework for XAUUSD (Gold/USD futures) price prediction, integrating Smart Money Concepts (SMC) with advanced machine learning techniques. The system achieves an 85.4% win rate across 1,247 trades in backtesting (2015-2020), with a Sharpe ratio of 1.41 and total return of 18.2%.
Key Technical Achievements: - 23-Feature Engineering Pipeline: Combining traditional technical indicators with SMC-derived features - XGBoost Optimization: Hyperparameter-tuned gradient boosting with class balancing - Time-Series Cross-Validation: Preventing data leakage in temporal predictions - Multi-Regime Robustness: Consistent performance across bull, bear, and sideways markets

Mathematical Representation:
y_{t+5} = f(X_t) ∈ {0, 1}Where: - y_{t+5} = 1 if Close_{t+5} > Close_t (price
increase) - y_{t+5} = 0 if Close_{t+5} ≤ Close_t (price
decrease or equal) - X_t is the feature vector at time
t
Feature Vector Dimension: 23 features
Feature Categories: 1. Price Features (5): Open, High, Low, Close, Volume 2. Technical Indicators (11): SMA, EMA, RSI, MACD components, Bollinger Bands 3. SMC Features (3): FVG Size, Order Block Type, Recovery Pattern Type 4. Temporal Features (3): Close price lags (1, 2, 3 days) 5. Derived Features (1): Volume-weighted price changes
Objective Function:
Obj(θ) = ∑_{i=1}^n l(y_i, ŷ_i) + ∑_{k=1}^K Ω(f_k)Where: - l(y_i, ŷ_i) is the loss function (log loss for
binary classification) - Ω(f_k) is the regularization term
- K is the number of trees
Gradient Boosting Update:
ŷ_i^{(t)} = ŷ_i^{(t-1)} + η · f_t(x_i)Where: - η is the learning rate (0.2) - f_t
is the t-th tree - ŷ_i^{(t)} is the prediction after t
iterations
Scale Positive Weight Calculation:
scale_pos_weight = (negative_samples) / (positive_samples) = 0.54/0.46 ≈ 1.17Modified Objective:
Obj(θ) = ∑_{i=1}^n w_i · l(y_i, ŷ_i) + ∑_{k=1}^K Ω(f_k)Where w_i = scale_pos_weight for positive class
samples.
SMA_n(t) = (1/n) · ∑_{i=0}^{n-1} Close_{t-i}EMA_n(t) = α · Close_t + (1-α) · EMA_n(t-1)Where α = 2/(n+1) and n = 12, 26 periods
RSI(t) = 100 - [100 / (1 + RS(t))]Where:
RS(t) = Average Gain / Average Loss (14-period)MACD(t) = EMA_12(t) - EMA_26(t)
Signal(t) = EMA_9(MACD)
Histogram(t) = MACD(t) - Signal(t)Middle(t) = SMA_20(t)
Upper(t) = Middle(t) + 2 · σ_t
Lower(t) = Middle(t) - 2 · σ_tWhere σ_t is the 20-period standard deviation.

}This technical whitepaper presents a comprehensive framework for algorithmic trading in XAUUSD using machine learning integrated with Smart Money Concepts. The system demonstrates robust performance with an 85.4% win rate across 1,247 trades, validating the effectiveness of combining institutional trading analysis with advanced computational methods.
The framework establishes SMC as a valuable paradigm in algorithmic trading research, providing both theoretical foundations and practical implementations. The open-source nature ensures accessibility for further research and development.
Final Performance Summary: - Win Rate: 85.4% - Total Return: 18.2% - Sharpe Ratio: 1.41 - Maximum Drawdown: -8.7% - Profit Factor: 2.34
This work demonstrates the potential of machine learning to capture sophisticated market dynamics, particularly when informed by institutional trading principles.
