Overview some vendors getting historical price

26 ม.ค. 2022

I tried to connect some vendors: IEXCloud, TD Ameritrade, Yahoo Finance, Rapid API, Alpaca, CNBC, and Tiingo I have some notes:

• IEXCloud has no historical prices on timeframes: 5m, 15m, 1h, 2h, 4h but realtime this one is a good performance
  
• TD Ameritrade limit connection by minutes and no timeframes: 1h, 2h, 4h
  
• Yahoo Finance has timeframes but it returns fake data when there are many connections
  
• Rapid API is very slow maybe it coved many many third-party
  
• Cnbc delayed 2 minutes
  
• Alpaca limit connection
  
• Tiingo maybe is good, it has timeframes minute and hour, ex: 5m, 15m, 1h, 2h, 4h (excepting day and week)
  

So if you want to get price by timeframe for your application, you can choose Tiingo (paid monthly) or connected IEXCloud to get realtime
