Connectivity

Exchange FIX API Connectivity #

Financial Information eXchange, or FIX, is a standard protocol which can be used to enter orders, submit cancel requests, and receive fills. FIX API users typically have existing software that runs FIX for order management.

The baseline specification for the Exchange FIX API is mixed:

• Order Entry: FIX 4.2 SP2
• Market Data: FIX 5.0 SP2

Supported Endpoints #

INFO

Production
Order Entry (FIX42): tcp+ssl://
Market Data (FIX50): tcp+ssl://

Sandbox
Order Entry (FIX42): tcp+ssl://
Order Entry (FIX50): tcp+ssl://
Market Data (FIX50): tcp+ssl://

RESEND REQUESTS

Resend requests are not supported. Every connection establishes a new session and a new set of session sequence numbers.

FIX Gateway #

Before logging onto a FIX session, clients must establish a secure connection to the FIX gateway. See the available endpoints above.

TCP SSL #

If your FIX implementation does not support establishing a native TCP SSL connection, you must setup a local proxy such as stunnel to establish a secure connection to the FIX gateway.

Static IP #

HootDex does not support static IP addresses. If your firewall rules require a static IP address, you must create a TCP proxy server with a static IP address which is capable of resolving an IP address using DNS.

INFO

Changes are deployed every Sunday and Wednesday at or close to 10 AM GMT. At that time, a logout message is sent from the server to indicate the session is ending.

Ciphers #

HootDex supports TLSv1.2 with the following server ciphers:

SSL Tunnels #

Exchange FIX API endpoints only accept TCP connections secured by SSL. If your FIX client library cannot establish an SSL connection natively, you must run a local proxy that establishes a secure connection and allows unencrypted local connections.
