Trade Across Multiple Crypto Exchanges with One API
Connect multiple cryptocurrency exchange accounts into single API. Centralize your order routing process to get the best execution across exchanges.
What You Can Do with EMS API?

Multi-Exchange Order Routing
Route trading orders to multiple cryptocurrency exchanges through a single unified API. The system handles communication with each exchange.

Order Placement (Limit Orders)
Submit limit orders with full control over price, quantity, side (BUY/SELL), and execution parameters. All orders follow a standardized structure across supported exchanges.

Advanced Order Execution Controls
Configure time-in-force options such as GTC, IOC, FOK, and expiration-based orders. Apply execution instructions like post-only (maker), reduce-only, or cancel-on-disconnect.

Order Cancellation Management
Cancel individual orders using client or exchange IDs, or cancel all active orders on a selected exchange with a single request.

Real-Time Order Execution Reports
Receive live updates on order status, including transitions (NEW, PARTIALLY_FILLED, FILLED, CANCELED, REJECTED), fill details, and full status history.

Balance Management
Access and track account balances, including total, available, and locked funds, updated in real time across all connected exchanges.

Position Tracking and Monitoring
Monitor open positions with details such as quantity, entry price, unrealized PnL, leverage, and liquidation levels across exchanges.

Smart Order Routing (SOR)
Execute trades across multiple exchanges using algorithms like TWAP and VWAP. Orders are automatically split and routed based on timing, volume, and market conditions.

Trading via WebSocket & FIX
Manage orders, balances, and positions in real time using WebSocket or FIX protocols, with continuous updates and low-latency communication.

Exchange & Symbol Access
Retrieve supported exchanges, trading pairs, and symbol configurations including precision, base/quote assets, and identifiers for trading operations.
