How FIX API Works
How Does FIX API Work?
At its core, FIX API facilitates the exchange of structured messages between systems. These messages are composed of standardized tags, data fields, and message types that define the content and purpose of the communication. Here’s an overview of how FIX API works:
- Message Creation: Traders or algorithms create a message that could be a new order, a market data request, or an execution report. The system then structures the message in the format specified by the FIX Protocol.
- Message Formatting: Each message contains various tags that represent specific data points (e.g., price, quantity, order type). The message follows the FIX standard to ensure compatibility with other systems.
- Transmission: The message is transmitted through a secure connection to the recipient (e.g., broker, exchange, or liquidity provider) over a FIX session.
- Message Processing: Upon receiving the message, the recipient processes it according to its type. For example, an order message might result in a trade execution, while a market data request could return real-time prices.
FIX Message Format
A typical FIX message consists of:
- Tags: Unique identifiers for different data fields (e.g., 35=D for New Order, 55=EURUSD for currency pair).
- Data: The actual values being transmitted (e.g., price, quantity, order type).
- Message Types: The message type determines the purpose of the communication, such as order placement, trade execution, or market data request.
What is a FIX Session?
A FIX session refers to the ongoing connection between two systems (e.g., a trader and an exchange). The session maintains synchronization, manages message sequencing, and ensures error-free transmission of messages. During a session, various controls such as heartbeat intervals and message sequence numbers are employed to maintain the session’s integrity and ensure that no messages are lost.
