Who it's for

Built for active traders who keep a journal CSV and their own written trading rules.

What breaks, and when

A green week hides what rule breaks cost: in the example they took 490.00 of a 622.00 week.

The worked example it ships

WEEKLY JOURNAL REVIEW - week of 2026-09-28 to 2026-10-02 (trades_week40.csv)
14 trades read · account 10,000 · 1R = 100 · amounts in US dollars, after 2.00 fees per trade
R per trade = (exit - entry) x direction / (entry - stop) x direction, on that trade's own stop.

What it does not do

No signals, entries, targets or market opinion; it reviews trades you already took against rules you wrote.

FAQ

What is a Claude skill?

A folder with a SKILL.md, a method, fill-in templates and a worked example. Claude loads it when your request matches and follows that method instead of improvising.

How is this different from asking Claude without the skill?

The skill carries a fixed method, fill-in templates and a full worked example, so Claude follows the same structure every time instead of improvising a new one.

What does it not do?

No signals, entries, targets or market opinion; it reviews trades you already took against rules you wrote.

How do I install it?

Unzip into ~/.claude/skills/ (Claude Code) or upload it as a custom skill in the Claude app, then ask: "Here's my trade log for this week. What did my mistakes cost?". Nothing to run.

What do I get when I buy?

The zip. On Whop it is in your library as a download lesson with the zip attached; on Gumroad it is the product file.
