Building a stock-trading agent with ADK

This article provides a step-by-step tutorial on creating a stock-trading AI agent using Google's open-source Agent Development Kit (ADK). It covers setting up the project, installing dependencies (google-adk, alpaca-py), configuring API keys for Gemini and Alpaca paper trading, and defining an agent that fetches financial news, analyzes sentiment with Gemini 2.5 Pro, and executes trades based on a sentiment momentum strategy. The guide emphasizes using paper trades only and includes code snippets for environment setup and agent logic.
