Support for Oauth

Hi, does alpaca-backtrader-api support authenticating with Oauth access tokens? A quick look through the source code seems to imply that we can only authenticate with API keys.

Would adding support for Oauth be as simple as adding the oauth param to AlpacaStore and passing that parameter to API(tradeapi.REST)? If so, I can make a PR to add this functionality

Hi, it should work. inside AlpacaStore (line 234) we do this

self.oapi = API(self.p.key_id,
                self.p.secret_key,
                self.p.base_url,
                self.p.api_version)

check if your Oauth works by adding that

adding that if statement is not possible in the main repo. you could have a fork and do it there though the reason is that it is a patch for something it was not designed for, doing something like that could cause bugs in the future (just an example - someone forgets to add credentials and the streamer doesn’t start and no exception happens… he will not know why nothing works)

adding your credentials is never a good practice… so don’t do that (you may get unexpected results… if not now, maybe in a future commit) currently what happens is that the AlpacaBroker gets the REST interface from the AlpacaStore so if you initialize it there correctly it should probably work (but again, it’s not a good practice so operate with caution)

now… we have 2 streamers. one for prices, one for events. prices stream is not relevant for you since you use a different feed. the events are broker events… so I’m guessing you probably need that

in any case - do these actions only with paper trading and see if you get your desired results. also, please update it here so others may get that information
