What is the FIX API?
sFOX offers a FIX API, REST API, as well as a websocket feed, to access market data, manage your account, and create/cancel orders.
FIX (Financial Information Exchange) API is an electronic communications protocol commonly used instead of REST or websocket connections for financial transactions because of its clearly defined rules and methods. FIX is compatible with almost every commonly used network technology.
When is the FIX API a good option for traders?
While many APIs offer similar functionality in terms of data transfer, the FIX API furnishes users with several unique advantages that include the following:
When rapid transfer of large quantities of information is helpful
When quick and easy setup is desired because of FIX's standardized language and widespread acceptance
When designing proprietary algorithmic or black-box strategies
When integrating with C++, C# and Java programming languages
How do I connect via FIX?
The client will have to pass their API Key in the password field (FIX Tag 554) of the logon request (A). For full specifications on connecting and building upon our FIX API please see https://docs.sfox.com/.
