The formula
Losing days reduce total profit, so a red day makes the ratio worse even though the best day did not change.
A worked example
A 40% cap. Your first four days:
To pass, total profit must reach 2,400 ÷ 0.40 = $6,000. You need another $2,400, and no new day can exceed $2,400 or it becomes the new best day and raises the target again. In practice that means smaller, steadier days at the size you normally trade, not a second big swing to "finish it".
Common mistakes
- Trying to fix it with one more big day. If the new day beats the old best, the target moves up.
- Ignoring losing days. Every red day lowers total profit and pushes the share up.
- Assuming the rule is the same everywhere. Caps, scope and measurement differ by firm and product, and firms change them. Confirm on the firm's site.
How the RB journal tracks it
The journal's Consistency Rule Check shows your best day as a share of total profit against the limit you set for the account (tuned in Edit Account), with a bar that turns from safe to warning as you approach it.
