FIX API
Platforms & ToolsA standardized, high-speed order-routing protocol used by institutional and high-frequency traders instead of a graphical platform.
FIX (Financial Information eXchange) API is a standardized messaging protocol used across financial markets for high-speed, direct order routing and market data, favored by institutional traders and high-frequency trading operations over standard retail platforms like MT4/MT5. It gives more granular control and lower latency than a graphical trading platform, but it requires custom software development to actually use.
Most retail brokers reserve FIX API access for larger or professional accounts, given the infrastructure cost of supporting it and the sophistication generally required on the client side.
