If you are not a FIX API trader, you have to wonder what FIX API is and how it proves to be useful for you. Let's start thinking about improving online API trading as a connection between you and the liquidity provider that executes your trade-in reality. When traders trade via cTrader or MT4, they must accept your trade requests which are then converted to FIX messages and transferred through FIX API sessions to brokers that have been made with their personal liquidity providers. If we speak in terms of MT4, all these conversions are carried out via bridges.
'Bridge' is a plugin available on the MT4 server and is able to change the MQL language to something that meets the standard, or you can say FIX API messages. But when you trade through FIX API connections, you can bypass additional latency installed along with the use of this platform.
The term FIX is short for Financial Information eXchange that allows you to trade so that you can become one of the most active traders in modern times. FIX gives you a set of protocols that give you the opportunity to connect to FIX hosts and give you the opportunity to get incoming market data but also get and send order requests and execution confirmation messages.
