Seems too good to be true? What are the downsides? And what is the price?

@joshdance Yeah, I was trying to see if there's a spread they take or something. That's how many "free" trading platforms work. I can't find that information anywhere though.

@joshdance Thanks for the comment! Downside... this is built for developer-first in mind, so currently we only offer API but not any manual trading interface. Price - this is free!

Commission free sounds wonderful but what is your spread for the Dow Index for instance? There already are a lot of brokers out there that charge no commission but have swap and spread fees. If you do have spreads how do I check them out and see what they are? @yokokawa244 @umitanuki

@umitanuki @nick_kimes Maybe you are referring more to the FX or futures market, but for the US Stocks (currently Alpaca Trading API is only for the US Stocks), the spread is the National Best Bid & Offer (NBBO) and not set or charged by us but established by participants quotes on exchanges.

@yokokawa244 awesome thanks. Is there anyway I can see what that spread would be without funding an account?

@nick_kimes sorry if I sound like a broken radio, but NBBO and the price you get filled are not controlled by us but strictly regulated by the regulator that customers trade at NBBO prices (I originally come from the FX land where FX brokers decide spread and sometimes change around based on the market situation and to the customers hence different pricing in different brokers, but US stock market is very different and is the most strictly regulated market where prices users get must be at NBBO as regulated - of course there is high speed latency related conversation, but for regular individuals, not too relevant). I think it would make sense once you can pull the data through our API. You don’t need to open a brokerage account to use our API. You can just sign up with your email to login to the paper trading dashboard where you can create API key to start pulling the data. docs.alpaca.markets
