FIX API

Finery Markets FIX API is based on the FIX 4.4 specification.

Connection

Endpoints for connection are provided by FineryMarkets during the onboarding process.

Access is provided using IP-address whitelist, which is also set during the onboarding process.

Only TCP is supported, clients should connect using SSL.

You should configure 1 API key per session to guarantee a connection. Resend requests are not supported. Every connection establishes a new session and a new set of session sequence numbers.
