Important Configuration Notes#

HeartBtInt: Must be ≤ 30 seconds. The server enforces a maximum heartbeat interval of 30 seconds.
TargetCompID: Must be exactly 360X (with hyphen, not underscore).
SenderCompID: Will be provided by 360X upon account setup. This must match your registered identifier.
ResetOnLogon: Set to Y during initial testing to avoid sequence number issues. For production, consider N to maintain sequence continuity.

Sample Configuration Files#

Production Environment (QuickFIX Format)#

Sandbox Environment (QuickFIX Format)#

Before using:
1.
Replace YOUR_SENDER_COMP_ID with your assigned SenderCompID
2.
Ensure ./store and ./log directories exist
3.
Download the 360X data dictionary files
4.
Update dictionary file paths to match your setup

Data Dictionary#

360X uses a custom FIX 5.0 SP2 data dictionary that includes platform-specific tags and message types.

Required Dictionary Files#

1.
FIX50SP2-360X.xml - 360X custom application-layer data dictionary
2.
FIXT11.xml - Standard FIXT 1.1 transport-layer data dictionary

Obtaining Dictionary Files#

Contact your 360X account representative to obtain the FIX50SP2-360X.xml data dictionary file. The standard FIXT11.xml file is typically included with QuickFIX distributions.
