## [October 5, 2026] Reality Trading Guide: Added rToken Limit Order Trading Rules

Interface:
- Reality Trading Guide

Changes:
- Added rToken limit order trading rules: if a single UID's terminal orders on a single trading pair exceed 2,000 within a statistical cycle with a fill rate below 10%, the limit order function for that trading pair will be restricted (error code `41121`). The restriction is automatically lifted if the conditions are not triggered again in the next statistical cycle (re-evaluated daily at 04:00 UTC+8).
