How To Download S Amp;p 500 Data From Yahoo Finance Python
Mui Chaille
In the first approach, we will consider the finance module in python and it is a very easy module to work with. The other module we will talk about is yahoofinancials which requires extra effort but gives back a whole lot of extra information in return. We will discuss that later and now we will begin by importing the required modules into our code.
Coming down on a technical level, the process of obtaining a historical stock price is a bit longer than the case of yfinance but that is mostly due to the huge volume of data. Now we move onto some of the important functions of yahoofinancials.
The full information is ultimately sourced from Yahoo Finance and now you know how to import yahoo finance into python and how to import any stock or cryptocurrency price and information dataset into your code and begin exploring and experimenting with them. Good luck with your adventures and feel free to share your code with me on LinkedIn or feel free to reach out to me in case of any doubts or errors.
I am new to web-scraping and need to scrape yahoo finance to get stock data. I was able to scrape their historical data, however the highest frequency they have is 1 day intervals, and I am looking for higher frequency (something like 30 minutes to 1 hour). Unfortunately, yahoo finance and other financial sites (from what I looked into) don't release higher frequency than 1 day for free. My solution for getting higher frequency lies in the the chart feature yahoo finance has for every stock which is shown below:
As you can see, as you move along the x-axis, the cross-hairs follow the data line and the legend to the top left changes the relevant information (Open, High, Low, Close, Volume, % Change). So ideally, every day I would look at the graph for the data of a company for the past 24 hours, then somehow read the legend at the left as I move a cursor from left to right.
yfinance has a download function that uses threading for quick downloads. As mentioned in the comments, you can obtain 1m tick data but only for a 7 day period. You'll notice in the code below, if you enter a value greater than 7d, it will throw an error.
I'm coding a script that fetches information from the Yahoo finance API and even though the API is pretty slow it works for what I'm going to use it for. During testing of the script I found out that I got an IndexOutOfBounds exception and up on investigation I see that Yahoo Finance is returning stock quote information for the stocks I have except that its missing one day for one of the stocks, and I suspect that when using a wider time period it will miss more days as I have got that exception before when using a wider time period, but I thought it was something in my code that I could just fix later.
That the Yahoo finance API is missing entire days of stock quote information makes the API useless for me. Has anyone else experienced this, and is there any solution to it ? I'm guessing I would need to use another way to get the data.
Update 2:I tried another module named ystockquote and got the same result. I get information for thursday and friday, but not monday. If i ask for a different quote i get info from all three days. When i got to the yahoo finance site it has the stock information from monday in graphs etc.
Update 3:The data is now found for the GJF.OL which probably would have been related to a delay in the stock prices for the historical tables in the API as pointed out below in an answer. However, I was still able to receive stock price information from other stocks for the dates I did not receive stock price information from for the GJF.OL stock.
While I'm now receiving stock price information for the GJF.OL stock I tried to get the last 165 days of stock price information from the stocks, but there is 1 day missing from the NAS.OL stock meaning the dictionary returned does not contain any data for that day while the other stocks have that information. The stock is NAS.OL and the date is 3rd of August 2016 where the data is missing. Any ideas why this data is missing ?
Might it be the time zone difference? Try experimenting with different YFINANCE date ranges. e.g. add an extra day to your end date etc... There seems to be something odd with the returned data. Also I'm only seeing data from 10 AM and not from 9:30 AM. That's also puzzling.
Ever since Yahoo decommissioned their historical data API, Python developers looked for a reliable workaround. As a result, my library, yfinance, gained momentum and was downloaded over 100,000 enjoys 300k+ installs per month, acording to PyPi!
You should refer to Yahoo!'s terms of use (here,here, andhere) for details on your rights to use the actual data downloaded. Remember - the Yahoo! finance API is intended for personal use only.
fix-yahoo-finance aimed to offer a temporary fix to the problem by getting data from Yahoo! Finance and returning it in the same format as pandas_datareader's get_data_yahoo(), thus keeping the code changes in exisiting software to minimum.
The problem was, that this hack was a bit unreliable, causing data to not being downloaded and required developers to force session re-initialization and re-fetching of cookies, by calling yf.get_yahoo_crumb(force=True).
yfinance is a complete re-write of the libray, offering a reliable method of downloading historical market data from Yahoo! Finance's API, up to 1 minute granularity, in a more Pythonic way.
Trading, investing, and other financial professionals need access to financial data since investment research is reliant on it.
