Alpaca Data API Reviews and details

Social recommendations and mentions

• Why is trading info so slow?

  Have you looked at Alpaca's Market Data API or Polygon.io. Both premium options are reasonably priced and give you access to both historical and real time trades. Source: over 1 year ago

• Algo trading for dissertation

  I think https://alpaca.markets/data still offers free api keys for research purposes. Source: over 1 year ago

• Costs for Algo Traders

  Https://alpaca.markets/data - As you see you get 100% market coverage for all US exchanges and unlimited API / WebSocket access. They also have 1min bar historical data (I do not know about the tick level). I can not speak to the quality of the API Access as I have a TotalView subscription. Source: over 1 year ago

• API for Fund Analysis

  Free tier for researchers, now $99/month for the algotrading access (link: https://alpaca.markets/data). Source: almost 2 years ago

• Question about (somewhat) live market volume data

  Https://alpaca.markets/data free plan has 200 calls/minute limit which is what you want anyway. Source: about 2 years ago

• What tools do I need to start playing with the full data set?

  For a combination of data access and back testing, Alpaca might be good. It is geared toward developers, though, so depending on your technical skill level it might be a high barrier of entry. Https://alpaca.markets/data. Source: over 2 years ago

• Good API for streaming market data

  Looks like Alpaca just released their market data API. Also offering WebScoket streaming. Could be useful. Source: almost 3 years ago

• Show HN: I discovered a trading algorithm that returns ~24.85% annually

  This is mean reversion, right? Essentially fading market volatility. I recall an article on Bloomberg about a quant fund using VIX ETNs to implement something similar. Gradually adding short positions as volatility rises. Knowing it will dissipate once turmoil subsides. My recommendation: try entering a trading contest on Alpaca ;) https://alpaca.markets/data. - Source: Hacker News / almost 3 years ago
