Stock Market Telegram Bot

Create a Telegram bot that provides real-time financial data for stocks, making market information easily accessible through chat commands. This bot will help users quickly check stock prices, company information, and market trends without leaving their Telegram app.

What You'll Build:

A Telegram bot that responds to commands like /stock AAPL or /price TSLA, fetching live stock data from financial APIs and presenting it in a clean, readable format. The bot will handle multiple stock symbols, provide company details, and include basic market indicators.

Key User Stories:

• As a user, I want to get current stock prices by sending commands like /stock AAPL so that I can quickly check market values
• As a user, I want to view company information including market cap and sector so that I can understand the business context
• As a user, I want to see price change percentages and daily highs/lows so that I can assess stock performance
• As a user, I want to search for stock symbols by company name so that I can find tickers I don't know
• As a user, I want to set up watchlists for multiple stocks so that I can monitor my portfolio efficiently
• As a user, I want to receive help commands and usage examples so that I can learn how to use the bot effectively

Technical Implementation:

Use the Telegram Bot API for messaging functionality and a financial data API like Alpha Vantage or Yahoo Finance for stock information. Implement command parsing, error handling for invalid symbols, and rate limiting to manage API quotas. Store user preferences in a simple database and use webhooks or polling for message handling.
