AI Agent for Stock Market Prediction Roadmap

Phase 1: Data Acquisition & EDA

Goal: Collect historical NSE/BSE stock & options data and perform Exploratory Data Analysis.

  • Step 1.1: Identify Data Sources
    • Install yfinance & nsepy.
    • Read "Data Quality Challenges in Financial Time Series" (Nolte et al., 2018). [PDF/DOI]
    • Fetch 5 years of daily data for sample symbols.
  • Step 1.2: Storage Setup
    • Create folders: data/raw/daily, data/raw/intraday.
    • Save CSVs and verify consistency.
  • Step 1.3: Exploratory Data Analysis
    • Plot closing price series (Matplotlib).
    • Compute stats: mean return, std dev, skewness.
    • Visualize correlations with index.

Outcome: Raw dataset directory and an EDA notebook summarizing data insights.

Phase 2: Preprocessing & Feature Engineering

Goal: Clean data, handle missing values, scale series, and create features.

  • Step 2.1: Data Cleaning
    • Implement clean_time_series(df) to forward-fill gaps.
    • Detect outliers (Z-score) and clamp/remove.
    • Read Chapter 3 of "Practical Time Series Analysis" (Veri et al., 2020).
  • Step 2.2: Scaling & Stationarity
    • Compute log-returns: np.log(df.Close).diff().
    • Fit StandardScaler and save scaler.
  • Step 2.3: Feature Engineering
    • Add RSI, SMA via pandas_ta.
    • Encode cyclical time features.
    • Read "Feature Engineering for Financial Forecasting" (Zhang & Li, 2019).
  • Step 2.4: Dataset Splitting
    • Split: train 70%, val 15%, test 15%.
    • Optional rolling-window CV for intraday.

Outcome: Cleaned & feature-rich datasets ready for modeling.

Phase 3: Model Development & Training

Goal: Build and tune forecasting models across horizons.

  • Step 3.1: Baseline Models
    • Implement ARIMA with statsmodels.
    • Evaluate RMSE & directional accuracy.
  • Step 3.2: Deep Learning Models
    • Build LSTM in PyTorch.
    • Read "Deep Learning for Time Series Forecasting" (Fischer & Krauss, 2018).
    • Try TCN implementation.
  • Step 3.3: Hyperparameter Tuning
    • Use Optuna for tuning.
    • Log experiments in MLflow.
  • Step 3.4: Multi-Horizon Strategy
    • Separate models for minute vs weekly predictions.
    • Explore N-BEATS for multi-step forecasts.
  • Step 3.5: Final Model Training
    • Retrain on train+val and test hold-out.
    • Save final models and scalers.

Outcome: Trained, tuned models with documented performance.

Phase 4: Evaluation & Validation

Goal: Backtest and stress-test models for robustness.

  • Step 4.1: Backtesting Loop
    • Simulate rolling predictions on test data.
    • Compute metrics (RMSE, MAPE, accuracy).
  • Step 4.2: Stress Testing
    • Evaluate during volatile periods.
    • Adjust features/models if needed.
  • Step 4.3: Outcome Analysis
    • Document failure modes & improvements.
    • Check accuracy targets; revisit Phase 3 if necessary.

Outcome: Validated models with actionable insights.

Phase 5: Deployment & Integration

Goal: Deploy models locally/cloud and integrate AI agent.

  • Step 5.1: Inference Script
    • Create predict.py for forecasts.
    • Test locally.
  • Step 5.2: Cloud Deployment
    • Containerize & push to ECR/Registry.
    • Deploy on Lambda/Cloud Run.
  • Step 5.3: Agent Integration
    • Define LangChain tools.
    • Build Streamlit/Gradio UI.

Outcome: API and interactive agent interface.

Phase 6: Monitoring & Improvement

Goal: Continuously monitor, retrain, and expand.

  • Step 6.1: Logging & Monitoring
    • Log predictions vs actuals daily.
    • Dashboard metrics visualization.
  • Step 6.2: Automated Retraining
    • Schedule monthly retrains via scheduler.
    • Validate before deployment.
  • Step 6.3: Iteration & Expansion
    • Add symbols, macro features.
    • Integrate vector DB for news.

Outcome: Self-updating, robust system.
