I want to do some modelling and data visualization on historical stock data, including price, volume, financials, etc. Is there an public dataset available for stock price history? I looked at a few (Yahoo, Kaggle and Tiingo), but either they have a high cost, are missing some of the key financial information, or not sure they would be reliable and up to date. Free would be preferred, also established and reliable. If not, what are some good options for collecting the data myself? Maybe web scraping, or public api's etc. I plan to use this data in a machine learning project I am building.

In python, there are many libraries that can be used to get the stock market data. The most common set of data is the price volume data. These data can be used to create quant strategies, technical strategies, or very simple buy-and-hold strategies. The different Python libraries which provide stock market data are as follows:

Price-Volume Data

  • Daily data
    • Yahoo finance
    • Quandl
  • Minute level data
    • Alpha vantage

Futures & options price-volume data for Indian markets

  • NSEPy

Python Code and Overview of the Libraries can be found here

  • Thanks for the suggestions. Wondering if any of these also include assets to debts, earnings by quarter, ROA, ROI, etc. I may want to compare stock prices vs the value of the company. – Donald S Jun 17 at 4:04
  • Similar libraries are available in R and perl (and probably many other languages) – Marcus D Jun 17 at 13:48
  • Intrinio is not open data (this site is about open data). None of your other links are updated daily, which is the requirement of the question. – Nicolas Raoul Jun 19 at 2:39
