Ask HN: Whose API is the best source of stock market data?
No doubt some HN users have written programs to analyze stock market prices, screen companies, etc.
Presumably most data sources (to find historical prices, stats, etc for a ticker) for this are paid.
Let's say (because it's true) that I want to write an app to screen stocks; who would you recommend I use as a data source?
