The financial APIs market grows so quickly that last year’s post or platform is not a good choice this year. So in this story, I will show you the best 5 stock market APIs that I use in 2019.
Stock market data APIs offer real-time or historical data on financial assets that are currently being traded in the markets. These APIs usually offer prices of public stocks, ETFs, ETNs.
These data can be used for generating technical indicators which are the foundation to build trading strategies and monitor the market.
In this story, I mainly care about price information. For other data, there are some other APIs mainly for that use cases which will not be covered here.
I will talk about the following APIs and where they can be used:
