Before you trust the number, check how your firm counts

Firms measure the daily limit differently, and the difference decides whether you are inside it. Read your firm's rules for these three, in writing:

Measured from what?

  1. Yesterday's closing balance, today's starting balance, or your highest balance (trailing)

Open positions or closed only?

  1. Some firms count unrealized losses on open trades the moment they happen

When does the day reset?

  1. The firm's timezone and reset time, not yours

If your firm counts open losses, an open trade can breach the limit before you close it — another reason your own stop belongs well inside the line.

A stop only works if it's written before the loss

The number above is the easy part. Keeping it is the hard part, especially right after a loss — read how to stop revenge trading. Discipline Desk holds you to the rules you write: it journals every decision and scores your setup before you take it. Start with the free Nine-Point Checklist.
