The Polygon NATS Streaming API allows you to indirectly stream stock channels. Polygon.io uses a messaging broker called NATS to connect to a NATS cluster. For Polygon.io streams you must use the NATS library for your language. Please refer to the SDK’s tab for more information. It provides a way to access low latency, tick by tick TRADE and QUOTE data from 15+ exchanges. It offers an aggregate feed which gives you per second, or per minute updates with an overview of what happened in that timeframe and includes; Stock TRADES, Stock QUOTES and Stock. Polygon enables you to stream real-time market data.
The following is a list of historical changes that were made to this asset. Typically,
once an API is published on ProgrammableWeb.com, the data we keep about that asset gets updated over the course of its life. For example, the endpoint or home page of the documentation might change.
As a means of enforcing the integrity of our data, every time a non-trivial change is made to the data we keep about an asset,
we require the entry of some changelog text before that change can be saved. This way, we have a great audit trail of all
activity surrounding the asset. For each asset, the changelogs begins with the moment an asset is approved for publication on ProgrammableWeb.
