R Calculator

R is the center of the universe. Method units, not dollars. You set the risk unit before you enter; the calculator returns the size, the stop, the target and the tally. It does not negotiate with mood, caffeination, or your sense of what is or isn't a large amount of money.

1R recalculates from AUM, so it scales as you compound. Each trade locks its own R unit at the moment it opens. R expresses how much edge is in front of you — never the size you want. The survival levers (heat cap, cold-streak brake) sit outside per-trade sizing on purpose. Data lives in this browser only: use Export at the bottom to back it up.

Pre-trade check

The stop sits where the idea is plainly wrong — not where my desired size wants it. Not Day One on a parabolic mover. The concept is named, and today's setup resembles ones already in the database. Exits and hinges are defined before entry.

06 · Data Management

Live marks — Finnhub key (optional)

With a key set, Refresh marks appears on the Open Positions header and the book also self-refreshes once a minute. Only ticker symbols are sent, and only when a refresh runs.

Everything lives in this browser's localStorage. Clearing site data wipes it. Nothing leaves this machine except the ticker symbols you send to Finnhub yourself, if you set a key for live marks.

Not financial advice — a calculator.
