FIX API

FIX API is a protocol for financial information exchange.

Native FIX Engine | FIX Initiator, Aggregator & Acceptor

FIX Is Native, Not Bolted On

MT4/MT5 needs a third-party bridge plugin to speak FIX. Fintechee doesn’t — FIX connectivity is part of the Trading Core itself.

FIX Initiator

  • No FIX Bridge plugin required
  • Supports multiple LPs, multiple FIX channels, and multiple FIX accounts
  • Standard mode: many trader accounts route through one shared, anonymous FIX account
  • Advanced mode: account-level FIX mapping — each trader account maps to its own FIX account for granular LP routing

FIX Price Aggregator

Connects to multiple FIX channels simultaneously and automatically routes A Book orders to the lowest-cost channel available at that moment. Used for best execution, LP selection, and server-side arbitrage opportunities.

FIX Acceptor

Accepts external FIX orders and executes them against a bound internal account.

Currently supported: Market Order, FOK
Not yet supported: Pending Order, Partial Fill
Potential use cases: receiving orders from other brokers, acting as an execution system, and monitoring MT4/MT5 trading activity (this last use case remains a theoretical scenario not yet fully validated).

FAQ

Does Fintechee require a FIX bridge plugin like MT4/MT5 does?

No. FIX connectivity is native to the Fintechee Trading Core.

How does the FIX Price Aggregator choose which LP to execute against?

It connects to multiple FIX channels at once and routes A Book orders to whichever channel offers the lowest cost at that moment.

What order types can the FIX Acceptor currently process?

Market Order and FOK are currently supported; Pending Order and Partial Fill are not yet supported.
