Version 1.0 | Date: September 18, +2025 | Author: Jonus Nattapong Tapachom
+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.
