Pandas Datareader library is down since December 16, 2022. I use it to get stock market historical data. This has happened before when it was my first attempt to download historical data. I figured to leave the task and go on with the next task and came after a few days and it went back to normal that is why this recent event is not a surprise for me.
I like using this library because it is very useful and very simple to use but the only downside is the downtime is quite long, the developers are not able to fix it quickly. It has been 3 days and it still unuseable so I have to try its twin library(YFinance) if it still works. The output and features of this library is very much identical to Pandas Datareader but with a few other options like the ticker info(which is also currently down). And speaking of the ticker info method, this feature of yfinace is very slow. Way... way too slow.
In my trading platform program, I currently use yfinace ticker info to display some information about the ticker(obviously) but it has no use for me so probably that feature is needed by institutional investors who must have to analyze the ticker(company) from ground up which leads me to decide to just remove it from my program since I am not an institutional investor. And I also use the panda data reader to get historical data of the ticker which is currently down and maybe who knows when will it be up. So it is a huge problem for me because both yfnance ticker info is slow and currently down (not really, I noticed that it still works but a lot of the fields that I am using had disappeared and I do not know why) and the pandas data reader is down.
As my first option, I should to try if yfinace(before exploring other alternatives) function or methods to get the historical data are still working and I am glad that with the result of my experiments, it still works. So for those who have downloaded/copied my program, I am posting the latest version of my program and for those who want to try, this is the latest version:
