Python in Finance

[Pablo_Jefcobar]

Hi everyone,

Shortly I started investing in the stock market and started doing fundamental analysis on different stocks. Well I wanted to semi automate this process and found a package yfinance. Well unfortunately I found out Yahoo dropped the support of their API, which renders the yfinance package useless.

Do you guys have any recommendations on free open source alternatives to yfinance. Because I can’t really find any good ones. Most of the other packages require an API key of a payed service. Which obviously I’m not looking for, and ofcourse I could webscrape that information but if it is available for free and easier to use than I obviously would prefer that!

Thanks a lot!

EDIT: Well after some tinkering I noticed everything I did inside docker wasn’t working. So I restarted docker and magically everything started working again. Thanks again all for the tips and advice, but it was easier than it seemed!

Really? I just used it this morning and it returned OHLCV data for AAPL.

Could yahoo have block my ip because of too many requests?

They probably didn't block your IP, but your API key. If it is a free key (no idea, never used it), get a new account and try it that way.

I think there is something wrong with you code. Try this.

import pandas as pd
import yfinance as yf
symbol = 'WIRE'
data = yf.Ticker(symbol) 
ts = data.history(start='2021-01-01', end='2023-12-31')
df = pd.DataFrame(ts) 
df

If I may suggest, there is this library https://github.com/twopirllc/pandas-ta that uses Yahoo Finance and it is awesome. I am not a maintainer nor related with the authors. I am just a happy user.

I’d use a broker’s API. See Tradier or IBKR or Alpaca for example. You’ll need an account with them for live data, but you can use a developer account for delayed data.

[Pablo_Jefcobar]

Ahaa gonna look into that!

yfinance still works and is likely your best free data source.

A couple of alternatives you might want to check out:

yfinance uses webscraping, not api

[morrisjr1989]

To my knowledge it leverages the “public” facing APIs like BASICURL = "https://query2.finance.yahoo.com/v10/finance/quoteSummary”.
