🎯 Final Project Specifications

1. The Core Application

A comprehensive, production-ready Streamlit dashboard featuring a sleek dark-mode UI, custom KPI metric cards, and highly interactive Plotly graphs.

2. Live Data Segments

1. Stock Market: Integrated with Alpha Vantage API for daily tracking and moving averages.
2. Cryptocurrency: Integrated with CoinGecko (100% Free API) for tracking trending tokens and historical market caps.
3. Weather: Integrated with OpenWeatherMap for live city-based forecasting and environmental analysis.
4. Forex (Currencies): Replaced the Energy segment with a robust Forex tracker using the open-source Frankfurter API (No API key required).
5. Custom CSV: A highly resilient file ingestion pipeline allowing users to upload personal datasets, auto-detect dates, and run predictive modeling on any numerical column.

3. Forecasting Models

The platform is equipped with four distinct forecasting algorithms to handle any type of data pattern:

• ARIMA / SARIMA: Statistical modeling for stationary data.
• Facebook Prophet: Optimized with US Holiday tracking for highly seasonal business/financial data.
• LSTM Neural Networks: Built with TensorFlow. Hardened with 50-epoch training cycles and ReduceLROnPlateau for highly dynamic weight adjustments.
• Exponential Smoothing (Holt-Winters): Classical statistical smoothing initialized with use_boxcox for error-free trend tracking.

4. Analytical Utilities

• Stationarity Testing: Augmented Dickey-Fuller (ADF) tests to mathematically prove dataset stability.
• Anomaly Detection: Automated Z-score outlier detection to highlight unnatural market/weather spikes.
• Seasonal Decomposition: Separates time series into exact Trend, Seasonality, and Residual components.

🚀 Deployment Plan

Platform: Streamlit Community Cloud (free, easy, purpose-built)

Steps to Deploy:

1. Version Control: Push the entire project folder to a public or private GitHub repository.
2. Connect to Streamlit: Log in to Streamlit Community Cloud and link your GitHub account.
3. Deploy App: Click "New App", select your repository, and set the main file path to app.py.
4. Configure Secrets: Once deployed, go to the app's Advanced Settings -> Secrets on the Streamlit dashboard and securely paste your API keys:

   ALPHA_VANTAGE_API_KEY = "your_key_here"
   OPENWEATHER_API_KEY = "your_key_here"
   

5. Launch: The app will instantly build the Python environment using your requirements.txt and go live globally!
