Quantrade

An advanced stock price prediction system that combines LSTM deep learning with sentiment analysis of financial news to improve forecasting accuracy.

Quantrade uses LSTM neural networks and financial news sentiment analysis to provide more accurate stock price predictions by incorporating market sentiment with historical trends. Built with Python, PyTorch, Flask, MongoDB, AWS S3, and NLTK.

Features

• AI-driven stock price prediction using LSTM neural networks
• Real-time financial news sentiment analysis using NLTK VADER
• 25% improved forecasting accuracy through news integration
• Interactive web interface with real-time predictions
• Historical data caching with MongoDB
• Secure data storage with AWS S3

Tech Stack

• Python
• PyTorch (LSTM implementation)
• scikit-learn (Data preprocessing)
• yfinance (Stock data)
• Flask (Web interface)
• MongoDB (News caching)
• AWS S3 (Data storage)
• NLTK (Sentiment analysis)

Setup

1. Clone the repository
2. Install dependencies:

pip install -r requirements.txt

3. Set up environment variables in .env:

NEWS_API_KEY=your_newsapi_key
MONGODB_URI=your_mongodb_uri
