Market Data source Real Time iOS Mac OS X
I am developing a program that runs custom indicators that I find difficult or impossible with most charting packages. I have the base program down now but I am finding it difficult to get the market data I need.
I started off with Quandl free data and moved to Barchart. They have good data but only Java for streaming data.
I need some kind of API that can stream into a Mac OS X or iOS application. The charting library I am using now only works in Mac, iOS and Android. I was unable to find a good looking and functional charting package for Java.
Streaming real time data is preferred.
