Introduction

The Trading API is divided into the Trade API and Data Events API, supporting trading and order status change subscriptions via HTTP and gRPC protocols. Its purpose is to provide investors with convenient, fast, and secure trading services.

To simplify the integration process, we provide SDKs for Python and JAVA. These SDKs are fully featured and enable developers to get started quickly.

Main Features:

Trade Management: Create, modify, and cancel orders.

Subscribe to Real-Time Information: Subscribe to order status changes.
