Dhelm Gfeed Python Client Package

Dhelm-gfeed-python-client is a python client library to access and integrate stock market data from Global Financial Datafeeds LLP with your application.

To use this library you must subscribe to web socket api with Global Financial Datafeeds LLP and get your API key and web socket endpoint URL. Programmatic access to data obviously provides better control over your algorithm. You access the raw data from your data provider, then feed into your own application and do whatever analysis you want.

Using Dhelm-gfeed-python-client you can plug data from web socket api into your application directly.

For detailed integration and usage guidelines, please read through the documentation.
