This is a while I’m trying to find historical stock data to build an AI system. Sadly it’s not as easy as it appears. I’m putting together my findings here:
- Option 1: Using Yahoo’s CSV approach above you can also get historical data!
You can reverse engineer the following example:
sn = TICKER
a = fromMonth-1
b = fromDay (two digits)
c = fromYear
d = toMonth-1
e = toDay (two digits)
f = toYear
g = d for day, m for month, y for yearly

- Option 2: With less than 100$ one can get the end of day data straight from CSI data, this is where Yahoo gets their EOD data as well AFAIK. They have an API where you can extract the data to whatever format you want.
- Option 3 : For playing around with some intraday data I’d look into IQFeed, they provide several APIs to extract historical data, although they are mainly an outfit for real-time feeds. But here there are quite a few options, some brokers even provide historical data downloads via their APIs, so just pick your poison.
- Option 4 : Then, if you need the real stuff (level II order book, all ticks as they have happened at all exchanges) one “affordable”, yet excellent option is Nanex. They’ll actually ship you a drive with terabytes of data. Its about $3k-4K per year of data. But trust me, once you understand how hard it is to get good intraday data, you won’t think this is very much money at all.
