Vero OMS API

Channel

order:{notificationType}:{accountId}

Mô tả

Thông báo giao dịch/tài khoản. Các topic hỗ trợ gồm Deposit, ForceClose, MarginCall và Withdraw.

WebSocket URL

wss://streaming.verolabs.co/connection/websocket

Các ví dụ bên dưới subscribe vào:

order:MarginCall:ACC123456

Thay MarginCall và ACC123456 bằng topic thông báo và ID tài khoản cần subscribe.
