LPM (Long-Term Price Movement) Prediction System

A Deep Learning Project for Stock Price Forecasting and Trading Signal Generation

🎯 Project Overview

LPM is an advanced machine learning system designed to predict long-term stock price movements using deep learning. It leverages the Temporal Fusion Transformer (TFT) model—a state-of-the-art attention-based architecture—combined with sophisticated feature engineering to generate probabilistic price forecasts and actionable trading signals.

Unlike traditional technical analysis or simple price-prediction models, LPM:

  • Processes multiple stocks simultaneously with shared representations
  • Generates quantile predictions (not just point estimates) to capture uncertainty
  • Creates 50+ engineered features including momentum, volatility, price action, and statistical indicators
  • Handles multi-horizon predictions (1-step, 5-step, 10-step ahead forecasts)
  • Integrates production-ready infrastructure with PostgreSQL, MLflow tracking, and API endpoints
  • Scales to institutional-level backtesting with millions of data points

Use Cases

  • Quantitative Trading: Generate buy/sell signals based on probabilistic predictions
  • Portfolio Optimization: Predict price movements for risk management
  • Market Analysis: Understand market regimes and volatility patterns
  • Research: Experiment with cutting-edge time-series deep learning

📖 Step-by-Step Running Process

The project follows a 3-stage pipeline:

Stage 1: Data Extraction

Fetches historical stock data from Yahoo Finance and stores it in PostgreSQL.

python3 -m initialization.dataExtraction

What it does:

  • Retrieves OHLCV (Open, High, Low, Close, Volume) data for 500+ US Nasdaq stocks
  • Date range: 2000-01-01 to today
  • Stores raw data in us_ohlcv PostgreSQL table
  • Logs progress for each stock symbol

Output:

  • PostgreSQL table: us_ohlcv (~11.7M rows, ~1.5GB)
  • Logs: logs/ingest_*.log

Expected Duration: 30-60 minutes (depends on internet speed)

Stage 2: Feature Engineering

Computes 50+ technical and statistical features from raw OHLCV data.

python3 -m featureEngineering.featureEngineering

What it does:

  • Reads raw data from us_ohlcv table
  • Computes all feature categories (see Features section above)
  • Applies Z-score normalization
  • Stores featured data in featured_us_ohlcv table
  • Key insight: Features are cross-sectionally normalized (comparing across stocks)

Feature Categories Computed:

Category Features Purpose
Price Action Returns, Log Returns, Gaps, Candle Body, Wicks Directional movement capture
Momentum RSI, ROC, Stochastic, CCI, TSI Oscillator signals
Volatility Bollinger Bands, ATR, Standard Deviation Risk measurement
Volume OBV, CMF, Volume SMA Strength confirmation
Regime ADX, Trend Direction Market condition
Statistical Z-scores, Correlations, Skewness Distribution properties
Patterns MACD, EMA, SMA Trend identification

Output:

  • PostgreSQL table: featured_us_ohlcv (~7.7M rows, ~7.8GB)
  • Z-normalized features for model input

Expected Duration: 45-90 minutes

Database State After This Stage:

SELECT COUNT(*) FROM featured_us_ohlcv;
-- count: ~7,717,473

2. Feature Engineering Details

Why 50+ Features?

Traditional price prediction only uses OHLCV (5 features). LPM uses 50+ because:

Traditional Approach:

features = ['open', 'high', 'low', 'close', 'volume']  # 5 features
# Problem: Limited market context, poor generalization

LPM Approach:

features = [
    # Price dynamics (10+)
    'returns', 'log_returns', 'gaps', 'candle_body', 'upper_wick', 'lower_wick',
    
    # Momentum (8+)
    'RSI_14', 'ROC_12', 'Stochastic_K', 'CCI_20', 'TSI', 'MACD', 'Signal_Line',
    
    # Volatility (6+)
    'BB_Upper', 'BB_Middle', 'BB_Lower', 'ATR_14', 'Std_Dev_20',
    
    # Volume (4+)
    'OBV', 'CMF', 'Volume_SMA_20',
    
    # Regime (3+)
    'ADX_14', 'Trend_Direction', 'Market_Regime',
    
    # Statistical (8+)
    'Z_Score_Price', 'Correlation_Market', 'Skewness', 'Kurtosis',
    'Cross_Stock_Percentile', 'Normalized_Volume', 'Price_Normalized',
    
    # Cross-sectional (7+)
    'Sector_Average', 'Industry_Relative_Strength', 'Volume_Ratio_Market',
]
# Benefit: Rich feature representation, better model generalization

Feature Normalization Strategy

Z-Score Normalization (Cross-sectional):

normalized_feature = (feature - mean_across_stocks) / std_across_stocks

Why Cross-sectional?

  • Captures relative market positioning
  • Makes features comparable across stocks
  • Reduces impact of outliers
  • Improves neural network convergence

3. Temporal Fusion Transformer (TFT) Model

Why TFT over LSTM/GRU?

Aspect TFT LSTM GRU
Interpretability ✓ Attention weights reveal important features ✗ Black box ✗ Black box
Variable Selection ✓ Automatic feature importance ✗ Uses all features ✗ Uses all features
Quantile Prediction ✓ Native support for uncertainty ✗ Single point estimate ✗ Single point estimate
Multi-Horizon ✓ Efficient for multiple steps ⚠️ Iterative/slower ⚠️ Iterative/slower
Training Speed ✓ Parallelizable attention ✗ Sequential ✗ Sequential
Multi-Task ✓ Share representations across stocks ⚠️ Harder to implement ⚠️ Harder to implement

TFT Architecture

Input: (Batch=32, TimeSteps=60, Features=50)
    ↓
Variable Selection Network
├─ Learns importance weights for each feature
├─ Reduces effective feature dimension
└─ Output: Weighted features (50 → 16)
    ↓
Encoder Stack (3 layers)
├─ Multi-head Self-Attention (4-8 heads)
├─ Position-wise Feedforward Networks
├─ Layer Normalization & Residual Connections
└─ Captures temporal dependencies
    ↓
Decoder Stack (3 layers)
├─ Masked Multi-head Attention (prevents future leakage)
├─ Cross-Attention to encoder outputs
├─ Captures decoder context
└─ Generates predictions
    ↓
Quantile Output Heads
├─ Generates 0.1 quantile (pessimistic)
├─ Generates 0.5 quantile (median, most likely)
├─ Generates 0.9 quantile (optimistic)
└─ Output: (Batch=32, TimeSteps=3, Quantiles=3)

Quantile Prediction Advantage

Instead of single point predictions:

Traditional: Price tomorrow = $150.00
Problem: False confidence, actual could be $148-$152

LPM generates uncertainty ranges:

10th percentile: $148.00 (pessimistic)
50th percentile: $150.00 (median, most likely)
90th percentile: $152.00 (optimistic)

Interpretation:
- 80% confidence price will be between $148-$152
- Better for risk management
- Enables probabilistic trading signals

4. Model Evaluation Metrics

Time-Series Forecasting Metrics

Metric Formula Interpretation
MAE $\frac{1}{n}\sum|y_i - \hat{y}_i|$ Average absolute error in price units
RMSE $\sqrt{\frac{1}{n}\sum(y_i - \hat{y}_i)^2}$ Root mean squared error (penalizes outliers)
MAPE $\frac{100}{n}\sum\frac{|y_i - \hat{y}_i|}{y_i}$ Percentage error (scale-independent)
Directional Accuracy $\frac{\text{# correct direction predictions}}{n} \times 100$ % of correct up/down predictions
Correlation $\text{corr}(y, \hat{y})$ Trend alignment

Trading-Specific Metrics

# Computed after signal generation
Sharpe Ratio = (avg_return - risk_free_rate) / std_return
# Higher = better risk-adjusted returns

Max Drawdown = max(peak) - trough / max(peak)
# Lower = less severe losses

Win Rate = # winning trades / total trades
# Higher = more consistent profitability

🎯 Signal Generation & Backtesting

Converting Predictions to Trading Signals

# Step 1: Get median predictions from TFT
median_pred = preds[:, :, 1]  # q=0.5 quantile

# Step 2: Convert to signals
signals = (median_pred > 0).astype(int)
# Signal = 1: BUY (expect price up)
# Signal = 0: HOLD/SELL (expect price down)

# Step 3: Optional - Use confidence intervals
upper_pred = preds[:, :, 2]    # q=0.9
lower_pred = preds[:, :, 0]    # q=0.1

confidence = upper_pred - lower_pred
# High confidence: wider spread indicates strong signal
# Low confidence: narrow spread indicates weak signal

# Advanced: Weighted signals based on confidence
signals = (median_pred > 0).astype(int) * (confidence > threshold)

Backtesting Framework

portfolio = []
pnl = []

for i, signal in enumerate(signals):
    if signal == 1:
        portfolio.append({
            'entry_price': prices[i],
            'entry_time': dates[i]
        })
    elif signal == 0 and portfolio:
        entry = portfolio.pop()
        exit_price = prices[i]
        trade_pnl = exit_price - entry['entry_price']
        pnl.append(trade_pnl)

# Calculate metrics
sharpe = np.mean(pnl) / np.std(pnl) * np.sqrt(252)  # Annualized
max_dd = np.min(np.cumsum(pnl)) / np.sum(pnl) * 100
win_rate = len([x for x in pnl if x > 0]) / len(pnl) * 100

🔧 Configuration & Customization

Modifying Training Hyperparameters

Edit modelTraining/modelTrainingHelpers/getTFTModel.py:

# Model Configuration
config = TemporalFusionTransformerConfig(
    hidden_size=32,              # Increase for more capacity (16-128)
    attention_head_size=8,       # Number of attention heads (4-16)
    num_hidden_layers=4,         # Transformer depth (2-6)
    intermediate_size=256,       # FFN hidden size
    hidden_act="relu",
    hidden_dropout_prob=0.1,
    attention_probs_dropout_prob=0.1,
    initializer_range=0.02,
    layer_norm_eps=1e-12,
    output_attentions=False,
    output_hidden_states=False,
)

Adjusting Training Parameters

Edit modelTraining/modelTrainingHelpers/getTrainer.py:

trainer = pl.Trainer(
    max_epochs=100,               # Increase for better convergence
    batch_size=32,                # Adjust based on GPU memory
    accelerator="gpu",            # or "cpu"
    devices=1,                    # Number of GPUs
    precision="16-mixed",         # Mixed precision for speed
    enable_progress_bar=True,     # Show training progress
    log_every_n_steps=100,
)

Feature Selection

In modelTraining/modelTraining.py, choose between:

# Option 1: Top Z-features (recommended)
training = getTimeSeriesDataset.getTimeSeriesDataset(
    train_df=train_df,
    feature_cols=z_features,  # Selected features
)

# Option 2: All features
training = getTimeSeriesDataset.getTimeSeriesDataset(
    train_df=train_df,
    feature_cols=feature_cols,  # All features
)

🚨 Troubleshooting

Issue 1: "No module named 'torch'"

pip install torch pytorch-forecasting pytorch-lightning

Issue 2: PostgreSQL Connection Failed

# Check if PostgreSQL is running
brew services list

# Start PostgreSQL
brew services start postgresql

# Test connection
psql -U postgres -d lpm_db

Issue 3: Training Hangs or Runs Slowly

Solutions:

  • Reduce max_epochs to 10-20 initially
  • Decrease batch_size if GPU memory is full
  • Set limit_train_batches=0.1 to use only 10% of data for quick testing
  • Enable progress bar: enable_progress_bar=True

Issue 4: Memory Errors

# Reduce batch size in getTrainer.py
batch_size=16  # instead of 32

# Or limit dataset size
limit_train_batches=50  # Use only 50 batches

Issue 5: Yahoo Finance Data Missing

Some symbols might not have enough historical data. The system skips these automatically and logs warnings.

# Check logs
tail -f logs/ingest_*.log

🔮 Advanced Features

1. Multi-Horizon Predictions

The TFT model generates predictions for multiple future steps:

# Predictions shape: (batch_size, horizon, quantiles)
# horizon = [1, 5, 10]  (next day, next week, next 10 days)

preds_1day = predictions[:, 0, :]   # 1-step ahead
preds_5day = predictions[:, 1, :]   # 5-step ahead
preds_10day = predictions[:, 2, :]  # 10-step ahead

2. Cross-Stock Transfer Learning

TFT shares representations across 500+ stocks, enabling:

  • Knowledge Transfer: Patterns from liquid stocks help predict illiquid ones
  • Data Efficiency: Reduces overfitting on sparse stocks
  • Robustness: Improves generalization through diversity

3. MLflow Integration

Track experiments automatically:

# Start MLflow server
mlflow ui --host 0.0.0.0 --port 5000

# Access at http://localhost:5000
# View: Model metrics, parameters, artifacts

4. Distributed Training

Scale to multiple GPUs:

trainer = pl.Trainer(
    accelerator="gpu",
    devices=4,  # Use 4 GPUs
    strategy="ddp",  # Distributed Data Parallel
    max_epochs=200,
)

🌍 Deployment

1. FastAPI Endpoint

app = FastAPI()
model = getModelFromCkpt("trained_models/lpm_tft_v1776927426.ckpt")

@app.post("/predict")
async def predict(symbols: List[str], horizon: int = 1):
    """
    Generate predictions for given symbols.
    Returns: {symbol: predictions, confidence}
    """
    results = {}
    for symbol in symbols:
        preds = model.predict(symbol, horizon)
        results[symbol] = preds.tolist()
    return results

# Run: uvicorn api.predict:app --host 0.0.0.0 --port 8000
