GoldPricePredictor

Gold Price Direction Predictor

This model predicts the next-day direction of gold prices (up or down) based on historical Antam gold price data and technical indicators.

Model Description

• Model Type: Binary Classification (Gradient Boosting / XGBoost / LightGBM)
• Task: Predict whether gold price will go up or down the next day
• Input: Feature vector with technical indicators (returns, lags, RSI, MACD, Bollinger Bands, etc.)
• Output: Probability of price going up (0-1), thresholded at optimized value for prediction

Intended Uses & Limitations

Intended Uses

• Financial analysis and decision support
• Educational purposes for machine learning in finance
• Research on gold price prediction

Limitations

• Trained on historical Antam gold prices only
• May not generalize to other markets or time periods
• Prediction accuracy is around 55-60% (better than random but not perfect)
• Requires up-to-date feature computation for real-time use

How to Use

Loading the Model

from huggingface_hub import hf_hub_download
from joblib import load

# Download model
model_path = hf_hub_download("theonegareth/GoldPricePredictor", "gold_direction_model.joblib")
model = load(model_path)

Making Predictions

The model expects a pandas DataFrame with the same feature columns used in training.

import pandas as pd

# Example feature vector (you need to compute these from your data)
features = pd.DataFrame({
    'ret': [0.01],
    'log_ret': [0.00995],
    'ret_lag_1': [0.005],
    # ... all required features
})

# Predict probability of going up
proba_up = model.predict_proba(features)[:, 1]
prediction = (proba_up >= 0.52).astype(int)  # Using optimized threshold

Feature Engineering

To use this model, you need to compute the same features from your gold price data:

• Daily returns and log returns
• Lagged returns (1-5 days)
• Rolling means and stds (3,5,10,20 days)
• RSI (14-day)
• MACD and signal
• Bollinger Bands
• Day of week and month

See the training notebooks for the complete add_features_adaptive function.

Training Data

• Source: Antam historical gold prices (Indonesian market)
• Period: [Insert date range from your data]
• Features: 25+ technical indicators
• Target: Next-day price direction (up=1, down=0)

Performance

Based on holdout testing:

• Accuracy: ~55%
• F1 Score: ~56%
• ROC AUC: ~58%

See the confusion matrix, ROC curve, and feature importance plots in the repository.

Training Procedure

1. Data preprocessing and feature engineering
2. Time-series split for cross-validation
3. Hyperparameter tuning with RandomizedSearchCV
4. Model selection based on F1 score
5. Threshold optimization for final predictions
