Each brokerage and each market data/news provider has its own API. There is very little standartization among them, and every one of them has its own peculiarities and difficulties. Some (I am looking at you, IB), have been created so long ago and grew, like a fungus, to create an almost incomprehensible agglomeration of specification that is hard to wade through.
Medved Trader can help you with connecting to these APIs. We have done all the work involved in understanding the APIs and writing code to login and use them in most efficient and bug-free manner. After all, that's our business model.
So - for our users we provide a simple, easy-to-code-to streaming Websocket JSON (or XML, if you prefer) API that will allow you to:
The API is asynchronous and very versatile. You can connect to one or several of the brokerages or data sources at the same time. It is as robust and bug-free as Medved Trader is.
