Get demo portfolio breakdown

Rate limit: 60 requests per 60 seconds. This is a shared quota — the same budget is consumed by a group of related endpoints, so calling any of them reduces what is left for the others (you cannot call each at the full rate independently). Endpoints sharing this quota:

• GET /api/v1/trading/info/demo/aggregate-portfolio
• GET /api/v1/trading/info/demo/pnl

Returns detailed portfolio information including active positions, pending orders, mirror trading details, and account balances. This endpoint provides a complete overview of the user's trading activity and current market exposure.
