API vs Data feed

[CFDplayer]

I am doing a paper on building up a connection via API to either ECN (currenex) or Market Maker (fxcm,IFX) on spot forex trading.

To distinguish the outline among API types (C+.Java,JS),and Data Feed (multi-providers,single data provider),and platform (MT4,Ariel), where and how to start to select?

Cheers,

What you want to do is far from clear. An API (Application Programming Interface) is simply library code that an application can call to "do things". Where "things" may be to subscribe to a data feed and receive data. A data feed API is simply a convenience for a programmer so that they do not have to do the leg work of encoding and decoding messages sent or received over the communication link on which the data feed operates. Comparing an API to a data feed doesn't make any sense at all.
