Fully automate stock trading by syncing Alpaca and Google Sheets

This workflow automates a stock trading strategy by integrating real-time market data from Google Sheets with the Alpaca paper trading API. It tracks daily stock sentiment scores, identifies the top-performing stocks, and automatically executes buy and sell orders to rebalance the portfolio.

Designed to work in tandem with an AI-powered stock sentiment analysis workflow, this solution bridges the gap between market insights and trading execution, providing a fully automated, algorithm-driven investment strategy for traders who want to put their research into action without manual effort.
