Yfinance Intermittently working

[locfinessemonster]

I have used yfinance for a while using a very old mac and haven't had any problems. I recently upgraded my computer to Windows 11 and am trying to run basic yfinance functions like yf.download in jupyter notebook on a chrome browser and I keep gettting the error message "No data found for this date range, symbol may be delisted" as well as error 10060. I have tried downgrading to older library versions and using the "pip install yfinance --upgrade --no-cache-dir" recommended fix but I am still getting this problem. The workaround I came up with is to keep retrying the yf.download and sleeping for a couple seconds if it fails. It seems to eventually download after around 10 tries or so but this doesn't seem to be the most elegant solution. I have tried changing my firewall settings and it doesn't seem like my computer is blocking anything. I am pretty stumped, if you have any suggestions I would really appreciate it!

Code with errors that I am seeing:

Work around code:

Longer sleep interval between requests seems to help me get it with less requests, still a mystery as to why I consistently can't get it on the first try.

Did you try 0.1.74 or older?

[jordangrodecki]

Also had this bug after building a new venv - spent ages before dropping back to 0.1.74 which works fine.

[ValueRaider]

We think we know why (related to #1076) and plan a release very soon.

I tried pip install yfinance==0.1.7.4 and still got the same issue. Tried yfinance==0.1.67 and got the same error

Awesome, thank you for the update.

Oh, if you have same problem with 0.1.74 or older then no, that needs investigation. What version was on your Mac?

I was using version 0.1.74 on my Mac and never ran into many issues. I tried running a Beautiful Soup Scraper on my Windows 11 machine, and I got error #10060 from that as well and that code never had any problems either on my old Mac. I wonder if I somehow got blacklisted by yfinance? I don't think I really ever sent too many requests yfinance though which seems odd.

[ValueRaider]

Any blacklisting is very temporary, so rolling back to 0.1.74 should have eventually restored normal behaviour.

For 0.1.75 and later, a release went out yesterday that should resolve problem.

[locfinessemonster]

Built both the yf v0.1.83 and v0.1.84 from the tar.gz files released yesterday and still having same issues unfortunately.

[ValueRaider]

Ok thanks for feedback on 0.1.84, but did rolling back to 0.1.74 solve?

Does the for w in range loop with sleep removed always encounter your error? If yes, how many iterations?

What is the actual loop you are trying to run?

What happens if you run in command line shell instead of Jupyter?

Yes, it pretty typically does, the standard range of iterations pretty typically seems to be between 2 and 10 What is the actual loop you are trying to run? The actual loop I am trying to run is trying to collect minutely price movement data for a list of stocks generally around 75 stocks long and export to csv. What happens if you run in command line shell instead of Jupyter? Running from command line using a virtual environment with yfinance==0.1.74 installed still gives me the same errors I have been seeing

[ValueRaider]

Curious that this only started with Windows, but the typical cause of these errors is spamming Yahoo with 100s requests/day - are you? If only running 1-2 times/day then unlikely to be Yahoo, which implies a Windows problem.

The solution to rate limiting is stop spamming Yahoo for data you could cache locally. Caching solutions:

• use requests_cache(see README) - setting expiration should help
• try yfinance_cache

[locfinessemonster]

Since this code has not been working properly, I haven't been running it at all outside of trying to debug yfinance. It's definitely a bit odd, I was thinking it was maybe my internet or firewall or something but I have some similar code that requests data from the WeBull API and it has been running without any problems.

I gave requests_cache a shot and still no luck.

I gave yfinance_cache a shot as well still getting an error

Do you think rolling back my os to Windows 10 could potentially fix the issues I am having?

[ValueRaider]

That last error looks like a Windows networking issue. Maybe start with Googling 10060 error code

[locfinessemonster]

I had some old tor code that I used to set a proxy on yf.download and now it seems as if everything is consistently working.

[ValueRaider]

If you don't mind, I'll tag this issue as "Windows" and close. I know Tor isn't ideal but I don't see what yfinance can do.

[locfinessemonster]

That sounds good, thanks for your help!
