Day Trader Skill

What it does

• Eleven /trader-* commands cover one trade end to end — /trader-scanner sweeps for opening-range breakouts, flags and oversold bounces, /trader-news watches headlines, /trader-entry calls the bar-by-bar trigger, /trader-exit sets stop and target before entry
• The Time Machine replays the rest of the session 10,000 times from the stock's own last 60 days of 5-minute bars, then re-runs the same rule on every past day it fired — honest odds before you risk a dollar
• Safety rails are structural — only /trader-broker can reach a brokerage, and only after /trader-risk returns PASS on that exact order and you type yes; paper trading via Alpaca's MCP server is the default
• Every tool is standard-library Python reading free public data — Yahoo Finance charts, Nasdaq Trader symbol lists, SEC EDGAR filings and House Clerk PTR disclosures; nothing to pip install

When to use it

Practicing day trading on real market data without real money at stake — every workflow ends in a ticket you approve and paper trading is the default. Also a reference for guardrail design in agentic tools: budget, risk and execution are separate skills, so the dangerous step is isolated, gated twice, and defaults to simulation.

Getting started

/plugin marketplace add Jakeschincariol/day-trader-skill
/plugin install day-trader-skill@day-trader-skill

# or clone for un-namespaced commands:
git clone https://github.com/Jakeschincariol/day-trader-skill.git
cp -r day-trader-skill/trader-* ~/.claude/skills/

Requires Python 3.8+, nothing to pip install. The SEC-backed skills (/trader-news filings, /trader-analyst) ask you to identify yourself: set "sec_user_agent": "Your Name you@example.com" in trader/config.json or export SEC_USER_AGENT. Broker execution uses Alpaca's MCP server, paper account by default.

Things to know

Day trading is where most retail traders lose money and the README is blunt about it: software that reads public data and does arithmetic, not financial advice. The Time Machine is a simulation from 60 days of bars — earnings, halts and headlines can do what those days never did. Yahoo Finance's chart endpoint is unofficial: it can lag, rate-limit or change. Stops are plans, not guarantees — in fast markets fills can land well past the stop price. FINRA removed the $25,000 pattern-day-trader minimum on June 4, 2026 (Regulatory Notice 26-10), but brokers may phase the change in until October 2027, so keep "pdt_guard": true if yours still applies the old rule.
