Overview

FIX Antenna reads the configuration parameters by default from the engine.properties file during initialization.

The user can also assign another name for the configuration file, such as the Engine::FixEngine::init(const std::string& aPropertiesFileName = "") call parameter.

For example:

Engine parameters

FIXCompIdCutoffMarker

Optional. This property allows the creation of multiple initiator sessions with identical Sender/Target CompIDs in the FIX messaging environment. By configuring a special pattern, appended to the Sender/Target during setup, the engine will strip this pattern (and any subsequent characters) from the CompID before sending a message to an external system. This configurable pattern ensures unique session identification while maintaining the consistency of Sender/Target CompIDs across various sessions.

Valid type: string

Usage Example

Configuration

1. Choose a cutoff marker, e.g., '-ID-'.

2. Set FIXCompIdCutoffMarker = '-ID-' in the FIX Antenna HFT configurations.

3. For each session, configure the internal CompIDs by appending the marker and a unique identifier, then the FIX Antenna HFT will remove this for external messages.

Example

• Before sending:

  • FIXCompIdCutoffMarker = '-ID-'

  • Session 1: Internal IDs: SenderCompID = 'TradeFast-ID-1', TargetCompID = 'ExchangeXYZ-ID-1'.

  • Session 2: Internal IDs: SenderCompID = 'TradeFast-ID-2', TargetCompID = 'ExchangeXYZ-ID-2'.

• After processing:

  • Session 1 & 2 external IDs: SenderCompID = 'TradeFast', TargetCompID = 'ExchangeXYZ'.

Outcome

Internally, sessions are differentiated as -ID-1, -ID-2, but externally, they appear consistent and originate from the same CompIDs.

Session parameters

To configure a session parameter for a session defined by SenderCompId (49) and TargetCompId (56) the following line should be added to the engine.properties file:

To configure the default session parameter the following line should be added to the engine.properties file:
