Generally third party apps will get data from market data providers like xignite etc. And where does xignite get the data? They pay for sessions to receive market data directly from all of the exchanges they care about. This data is not cheap from either source.
- iShrimp 9y agoNot cheap — not necessary. There are data providers like tiingo, quandl, intrinio (just to name a few) that provide quite a lot of data for reasonable prices.
- stefantheard 9y agoThat's true, everything is relative and it also depends what scale of market data you require. I think it's quite cheap to get end of day stock prices but if you want real time market data it gets steep. The closer you get to actual real time the more expensive seems to be the trend.
- iShrimp 9y agoThere is https://www.alphavantage.co https://www.alphavantage.co which is free now but we've stayed away from them since they were not replying to our enquiries and they do not have any ToS available. Cheapest realtime stock prices I've seen were ~500$; don't remember where that was though.
