I am looking to develope a virtual stock  market simulation... as i am novice dev , i can't afford live feed .

Will this API be useful for me ?

I am looking for an API which is free and provides data (Historical) from different sources.

@AP_REX If you're developing as a personal project, I would suggest taking a look at Yahoo's range of finance APIs. They aren't 100% rock solid, so I wouldn't recommend for a full scale production app, but they're free so they're perfect for small projects. Great data too.

Here's a good place to start if you're looking for historical data on stocks: https://developer.yahoo.com/yql/console/?q=show%20tables&env=store://dat... . You may be interested in taking a look at a Udemy course demonstrating the use of several of Yahoo's finance APIs.

If you need clean data to backtest strategies as precise as 1 minute interval, I would suggest to get a clean data source like http://intradata.co. They have both forex and stocks and it is ideal data for backtesting as they put their data in yearly files and simple to download from their site.

Then it is important to have a good optimization software with detailed reports to find patterns in different strategies. To visualize drawdowns for example with indicate what risk you take in the strategies.
