Currency-pair mapping
Confirm identifiers for majors, crosses and any source-specific suffixes. Quote orientation matters: inverting a pair changes both the numerical value and the bid/ask relationship, so it must be an explicit transformation.
Market data · deployment planning
Forex FIX API
Plan a FIX interface for FX subscriptions with a counterparty-approved symbol dictionary and session schedule.
Session acceptance
Validate subscription responses, heartbeat behavior and reconnect recovery in staging. A FIX login confirms transport state; acceptance also requires current quotes for the requested currency pairs and correct session-open status.
Requirements to confirm
- FX identifier dictionary
- Pair orientation and conversion
- Subscription response handling
- Login and market-state tests
Bring the proposed instrument list, source documentation and consumer workflow to a technical discussion. The agreed integration specification defines coverage, fields, usage permissions and acceptance tests.
Integration brief
Forex FIX API: what to agree before connecting
| Session agreement | Confirm the FIX version, identifiers, heartbeat policy and recovery procedure with the counterparty. |
|---|---|
| Market-data scope | Agree requested instruments, entry types, depth if applicable and update behaviour. |
| Instrument model | Map source identifiers, price precision, timestamps and required metadata. |
| Operational recovery | Test session reconnects and the treatment of application state after recovery. |
Use the counterparty specification
A FIX delivery plan for Forex must define the agreed version, session rules and market-data messages. Confirm snapshot and incremental semantics with the actual counterparty. Transport connectivity alone does not establish a complete, usable instrument state.
What to test
- Exercise logon, disconnect and recovery in a test environment.
- Compare the agreed snapshot with subsequent incremental updates.
- Record rejected symbols and the reason supplied by the counterparty.
