Day Trader Skill is 11 Claude skills that walk a day trade end to end: scan charts for setups, pull the news, time the entry, set the stop and target, size the position, check your risk limits, and hand a ticket to your broker. The Python is standard library only and reads free public data from Yahoo Finance, SEC EDGAR, Nasdaq Trader and the House Clerk. MIT, no API key.

Install it as a Claude Code plugin, add your name and email for SEC requests, done. The standout is the Time Machine: it replays the rest of the session 10,000 times from the stock's own recent bars and gives you the odds before you risk a dollar. Orders are optional and go through Alpaca's official MCP server (paper account by default, and paper trading is free) or the Interactive Brokers connector. The skill's script never sees your keys. Solo traders: free. Not a team tool.

The catch is day trading itself. The author's own fine print says most day traders lose money. Yahoo's chart endpoint is unofficial and can lag, and the simulation only knows the last 60 days. One commit, no updates since. Paper trade first.
