Longbridge Portfolio & Orders

Account data, order management, and portfolio analysis frameworks via Longbridge.

> **Response language**: match the user's input language — English / Simplified Chinese / Traditional Chinese. > **RULE: Response language priority**: English is the default when language is ambiguous. If the user input is only a slash command, command name, ticker / symbol, or contains no natural-language language signal, you MUST respond in English. Do not infer Chinese from trigger keywords, skill metadata, or examples.
