@william_gendron thanks for your question, it is on the roadmap, but not yet for the year of 2020 unfortunately... you don't trade US stocks but only options?
Will Gendron
@yokokawa244 Thank you for the reply. I invest a portion of my capital in stocks for the long term but my active trading is only in options.

@william_gendron that makes sense, thanks for the feedback! we will keep that in our mind :)

@yokokawa244 hey there! I’m someone who is looking to build apps/services. It seems like every potential user I talk to trades options. I’m sure you have good reasons for not prioritizing it, but no options makes it tough to build apps around.

@hnshah Thanks for hunting this :) This product is really for the builders who want to get involved in the stock market as a developer without paying!

Can I use Polygon data from my Polygon account directly? I’m not a US citizen and can’t access Live. I have been trying to adapt some scripts - momentum - have some of it working by plugging in my Polygon API details. But looks like some of the functions aren’t directly from Polygon library though they are input as such: api.polygon.historic_agg for example. I cannot find this anywhere in the Polygon documentation! :( Looking forward to working with the new data.

@interzone You can use your Polygon account directly. Alpaca SDK supports your own Polygon API key while using Alpaca API key for trading
AM H
@umitanuki Great! Is there Alpaca-Polygon specific functions native to the Alpaca python module that can still be accessed via using my Polygon API? Such as api.polygon.historical_agg() (from algo_momentum.py) or how to locate the alternative Polygon specific Rest function?

@yokokawa244 does this include mutual fund data?
Yoshi Yokokawa
Maker
@aloukissas hi Alex, unfortunately no. This is for the US stocks data only. you don't trade US stocks but only mutual funds?

@aloukissas @yokokawa244 We are working on a product using machine learning to recommend statistically superior MF and ETFs.

I’m curious to see how many developers on ProductHunt do algo trading or how many of them knew it was easy to start Doing so in minutes....

@datarade great point Kumar! we hope that with this Data API along with the staging environment (paper trading) on Alpaca makes this even easier to build lots of trading bots on US stock trading!

Useful service, it's difficult to find even FX prices in the internet, in contrast to crypto-trading, where every exchange has its own free API. The question: where will you get money from if everything is free? what is business model?
Tibor Kiss
Maker
@alexeykofman Fair question! You can find our business model detailed in our about page: https://alpaca.markets/docs/abou...
Alexey Kofman
@tibkiss Can you make API feed with forex prices? Maybe you already have it, but I failed to find instrument list on your web-site...
Tibor Kiss
Maker
@alexeykofman we only support us equities at the moment. Our partner, polygon.io provides forex prices though. You'll be provided access to their API if you have a funded account with us.

What it means that it's 99.95% accurate?
Yoshi Yokokawa
Maker
@elias_lankinen this is from 5 top US stock exchanges achieving up to 99.95% price accuracy compared to the SIP feed (100% coverage data feed)
Yan Cheng
Thank you for providing the API, for free. Do you mind to elaborate more, on how do you able to provide these APIs for free? What's your plan going forward, to make the service sustainable in long run? As, if we were to invest our resource to integrate with your API, we need to ensure such service will be there for a very long time. We really don't mind to pay, if we can generate return from our product, to cover the cost. As far as I know, the current available free APIs, are provided directly from a stock exchange named IEX. But, since their trading volume is way lower than well known NYSE, ... the provided information doesn't paint the market picture accurately. As developer, I can understand why most API providers aren't able to make API free. API providers are required to pay a huge sum of $ to stock exchanges themselves. Thank you very much for your effort.

@yokokawa244 This is awesome! would love to stop using polygon's endpoints. have a small request on the request parameter of the "get list of bars" endpoint though. Is it possible to add custom timeframes? Example 10m, 4h, 1W bars?
