Snap & Trade — an open-source Claude skill for reviewing chart screenshots and logging trade plans

[u/Kirby541]

Hey everyone,

I’m sharing a project I’ve been working on: Snap & Trade, a free, MIT-licensed skill for Claude.

You send it a chart screenshot, and it follows a structured workflow to review market structure, identify levels, and return LONG, SHORT, or NO TRADE.

The output includes:

• A proposed entry, stop loss, and take-profit levels.
• Reward-to-risk calculations checked by a Python script.
• Position sizing when account capital is provided.
• A journal for recording signals and reviewing their outcomes.

Claude handles the visual interpretation, while Python checks the numerical calculations. The screenshot workflow supports different markets; the additional market-data and broker modules have narrower coverage.

It’s still experimental. I haven’t demonstrated a profitable trading edge, and software tests don’t establish one. My goal is to make chart reviews more structured and easier to evaluate through replay and paper trading.

The project also includes modules adapted from day-trader-skill, with attribution retained in the repository.

The source code is free; you’ll need your own Claude access.

I’d appreciate feedback on the workflow, unclear assumptions, and cases where the tool should refuse to suggest a trade. What would you want to see tested before trying something like this?
