Redundant/alternate data sources

[achannarasappa]

Background
Currently, data is pulled from Yahoo finance's unofficial API. Given the API is not officially supported, it could be shut down, limited, or changed in some way that makes ticker unusable which presents a serious risk.

Additionally, there are data sources that may not be covered by Yahoo finance that users may find value in using with ticker's interface.

Request
In order to add redundancy and extensibility, it would be ideal to have the option to pull from different, configurable data sources.

Technical Details

• Implement of adapters (i.e. anti-corruption layer) for each data source
• Implement Yahoo finance adapter
• Define normalized internal data structures for quotes responses

Best free and real-time finance API I could find: https://finnhub.io/

It has a Go library, too, but I don't know if this is what you are looking for.
