Hi,
The second commit shouldn't appear here I guess. I'm pretty sure, that this cannot be merged with it.
Do separation for it, and optionally make comment in modified/new PR, that there is patch add-on for timeseries in you fork.

[chrislee35]

You're absolutely right. I messed that up and didn't fork it correctly. I will cancel this PR and submit a clean one.

@chrislee35 You fork it correctly, there is, that you just continue working on branch which was connected to this PR. What should be done, is to open new branch let's say "fix-datasource-yfinance-api":

1. check logs: git log --oneline --all and copy shorted hash of last commit from biolab:master
   (from main page: c19df2c) so I guess you can skip this step.
2. create that new branch with start-point that commit git branch fix-datasource-yfinance-api c19df2c
3. cherry pick commit fixed datasource.py. git cherry-pick f3c7ab6
4. Push and create PR where you choose that new branch and you can even deleted it from local computer (not a fork repo)

I don't know how you advanced in git, so please don't be angry on me if I told obviousness. 😃

[chrislee35]

I tried and now my repo is all broken. My git skills were unable to fix it.

It's not look that bad, I see that you didn't lost your patch. Discord?
