Installed via pip3 install alpaca-backtrader-api

Downgrading pandas from 1.3.5 to 1.2.5 has allowed me to import.

Should still state that this repo seems outdated. None of the examples work anymore.

can confirm the same happens on ubuntu

[cspipaon]

@mitchweaver @loopiezlol Are you guys able to run the example in README.md? I keep getting an error. I will open an issue for this shortly.

[mitchweaver]

@cspipaon No, all the examples are broken.

@mitchweaver I'm a new user to alpaca, is alpaca working for you at all or just the examples in README.md are broken? If I can get clarity from @cspipaon I can go in and help fix them or update the documentation as I have bandwidth this summer and want to start using/learning alpaca
