yahoo-finance

Overview

Yahoo Finance is a Claude Code skill built around a multi-ticker stock checker that fetches daily stock data using yahoo-finance2, computes technical indicators, and generates analysis reports as dated CSV files. It provides buy/hold/sell opinions weighted by indicator reliability, pattern detection, and volatility-adjusted risk management suggestions.

Key Features

• Multi-ticker analysis: Fetches and analyzes daily stock data for any number of tickers simultaneously using the yahoo-finance2 library.
• Comprehensive technical indicators: Computes RSI, Stochastic %K, Bollinger Bands, Donchian Channels, Williams %R, and Fear & Greed Index for each ticker.
• Automated trading opinions: Generates weighted BUY/HOLD/SELL opinions based on indicator reliability and basic pattern detection including ascending triangles, bullish flags, double bottoms, and falling wedges.
• Risk management suggestions: Provides volatility-adjusted stop loss, take profit, and trailing stop recommendations using ATR-based calculations.
• Slack notifications: Supports sending automated alerts to Slack webhooks when tickers return BUY or SELL opinions for real-time monitoring.

Who is this for?

This skill is designed for traders and investors who want automated technical analysis of stocks with actionable buy/sell signals and risk management parameters. It is particularly useful for those who want to integrate stock screening into CI pipelines or receive Slack alerts for trading opportunities without building custom analysis infrastructure.
