📝 Example Usage

Data Exploration

# View dataset structure
print(f"Dataset shape: {df.shape}")
print(f"Features: {df.columns.tolist()}")

# Target distribution
print(df['Future_Up_1d'].value_counts())
print(df['Future_Category_1d'].value_counts())

Feature Selection

# Technical indicators
technical_features = [
    'SMA_5', 'SMA_10', 'RSI', 'MACD', 
    'BB_Position', 'Volatility'
]

# Lagged features
lag_features = [col for col in df.columns if 'lag' in col]

# All targets
targets = [col for col in df.columns if 'Future_' in col]

Model Training Example

from sklearn.ensemble import RandomForestRegressor
from sklearn.model_selection import TimeSeriesSplit

# Prepare features and target
features = technical_features + lag_features
X = df[features].fillna(method='ffill')
y = df['Future_Return_1d']

# Time series split
tscv = TimeSeriesSplit(n_splits=5)
model = RandomForestRegressor(n_estimators=100)

# Train model
for train_idx, test_idx in tscv.split(X):
    X_train, X_test = X.iloc[train_idx], X.iloc[test_idx]
    y_train, y_test = y.iloc[train_idx], y.iloc[test_idx]
    
    model.fit(X_train, y_train)
    predictions = model.predict(X_test)

⚠️ Important Considerations

🔴 Data Limitations

• Survivorship Bias: Only current S&P 500 constituents included
• Market Hours: Regular trading session data only
• Corporate Actions: Historical adjustments may affect patterns

⚡ Usage Guidelines

• Temporal Order: Maintain chronological order in train/test splits
• Look-ahead Bias: Avoid using future information in features
• Market Regimes: Performance may vary across market conditions
• Feature Correlation: Technical indicators share underlying price data

📊 Data Quality

✅ Quality Assurance

• Industry-standard technical indicator calculations
• Comprehensive historical context with multiple time horizons
• Robust data validation pipelines
• Proper handling of corporate actions and market holidays

🔧 Data Processing

• Forward-fill methodology for missing data
• Vectorized operations for consistency
• No look-ahead bias in feature construction
• Dividend and split adjustments included
