Quant Stack Exchange's master list of data sources
Hundreds of free or paid economics and trading data sources.
There are also additional links and related questions, dozens of them.
Be advised the sources come and go, and data is not always reliable.
I use Yahoo Finance for OHLC data; they're much improved and still free, although they no longer permit mass downloads. Reputed to have 250,000 ticker symbols available. Includes many indexes and mutual funds, too.
Thank you. I shall now leave some emoticons.
