Monitor every order from submission to final execution through one normalized API.
Submitting an order is only the beginning. Trading applications also need to know when an order reaches the exchange, becomes active, receives partial fills, is completely filled, gets canceled, or is rejected. Without reliable execution reports, it's impossible to maintain an accurate view of open orders, portfolio exposure, or trading activity.
CoinAPI EMS provides normalized execution reports through REST, WebSocket, and FIX interfaces, allowing applications to track every stage of the order lifecycle across supported exchanges using one consistent data model.
An order rarely jumps directly from “submitted” to “filled.” It moves through multiple stages while being processed by the trading infrastructure. It may be routed to the exchange, become active in the order book, receive several partial fills, wait for cancellation, or ultimately be rejected.
Understanding exactly where an order is in that lifecycle is essential for trading platforms, execution algorithms, portfolio dashboards, and risk management systems.
CoinAPI EMS delivers normalized execution reports that let applications monitor every order from submission to completion without building exchange-specific integrations.
An execution report represents the current state of an order together with the information required to understand how that order has evolved over time. Rather than returning only the latest status, CoinAPI EMS provides the identifiers, quantities, pricing information, execution history, and fills needed to reconstruct the complete lifecycle of every active order.
| Field | What It Represents |
|---|---|
| Order Status | Current lifecycle stage of the order (New, Filled, Canceled, Rejected, etc.). |
| Status History | Timestamped history showing how the order progressed through each state. |
| Filled Quantity | Total quantity already executed. |
| Open Quantity | Remaining quantity available for execution. |
| Average Execution Price | Average price across all completed fills. |
| Fill History | Individual executions that contributed to the order. |
| Client & Exchange Order IDs | Identifiers assigned by both your application and the exchange. |
| CoinAPI & Exchange Symbols | Standardized and native market identifiers for every order. |
Execution reports differ significantly between exchanges. Field names, status values, identifiers, and reporting formats all vary, making it difficult to build applications that monitor orders across multiple trading venues.
CoinAPI EMS normalizes execution reports into a consistent model while preserving native exchange information whenever it's needed.
Every execution report reflects the current state of an order. As an order moves through the trading process, its execution report changes to reflect new events — from submission, through routing and execution, until it reaches a final state.
CoinAPI EMS normalizes these lifecycle states across supported exchanges, making it possible to build monitoring systems without translating dozens of exchange-specific status models.
Trading systems need more than individual updates — they need a complete and accurate view of every active order.
When a client connects, CoinAPI EMS first delivers an ORDER_EXEC_REPORT_SNAPSHOT containing all open orders for each connected exchange. From that point forward, every change is delivered through ORDER_EXEC_REPORT_UPDATE messages, allowing applications to keep their local state synchronized without repeatedly downloading the full order list.
Execution reports are one of the most important data streams inside a trading platform.
They allow applications to react immediately when an order changes state instead of relying on polling or periodic synchronization.
Whether an order is accepted, partially filled, completely executed, canceled, or rejected, your applications should always know exactly what happened.
CoinAPI EMS delivers normalized execution reports through REST, WebSocket, and FIX APIs, exposing order status, status history, fills, execution prices, remaining quantity, and identifiers in a consistent format across supported exchanges.
