Pair reference data
Base, quote, product status, precision, minimum size, and provider identifier.
FOREX API
Forex Trader API
Architecture guidance for currency-pair identity, executable bid and ask data, quantity units, session handling, and account-aware risk.
Developer overview
What this API category covers
A Forex Trader API needs explicit base and quote currencies, bid and ask prices, provider-specific precision, quantity units, and session conventions. A midpoint can be useful for charting but does not represent the executable spread. Conversions and position values also depend on the account currency and timestamp.
Do not choose an interface from a marketing checklist alone. Verify schemas, units, timestamps, permissions, failure behavior, testing conditions, and data-use terms for the exact product and account. A production integration should be able to recover authoritative state after a disconnect without guessing.
Capability map
Core integration responsibilities
Use these responsibilities to define architecture, acceptance tests, and provider evidence.
Bid and ask streaming
Executable sides, timestamp, freshness, spread, sequence, and reconnect behavior.
Historical rates
Clearly labeled bid, ask, midpoint, bar source, timezone, and corrections.
Order management
Units or lots, valid increments, order types, state, fills, and financing context.
Currency conversion
Account-base conversion, source rate, side, timestamp, and precision.
Risk monitoring
Net and gross exposure, leverage, open orders, loss limits, and market status.
Implementation
Production checklist
- Preserve base and quote direction.
- Label bid, ask, and midpoint separately.
- Document unit or lot quantity conventions.
- Use exact decimals and valid increments.
- Model sessions, rollover, and holidays.
- Convert exposure with time-stamped rates.
- Test spread changes and stale quotes.
- Do not equate margin with limited risk.

Forex Trader API questions
What is a Forex Trader API?
It is an interface that may expose currency-pair reference data, quotes, historical rates, account information, positions, or order workflows.
Why not use only the midpoint?
The midpoint hides the bid-ask spread. Trading, valuation, and conversion workflows may need a specific executable side.
What quantity units are used?
Interfaces may use currency units, lots, or provider-specific values. Store the original unit and convert explicitly.
How should timezones be handled?
Store timestamps in UTC while preserving provider and session context. Use explicit calendars for holidays and rollover behavior.
