realtime-securities

Go package for retrieving and analyzing realtime stock and option data.

The Provider interface allows new data providers to be added. Currently, the Tradier API has been partially implemented.

Please see the cmd directory for sample executables. Sample data is provided with this repo to run the showhistory command:

[realtime-securities] (master)$ cd cmd/showhistory/

[showhistory] (master)$ go build showhistory.go

[showhistory] (master)$ ./showhistory

Other commands require a Tradier authorization token to be placed in file resources/provider-auth/tradier to retrieve data from the provider. The format is "Bearer G6hw9LRbs72mChWP81jqPZzx39mF" (not a valid token).

The dailyprices command will retrieve and persist daily price summaries for the given date range. The quote command retrieves and displays realtime stock quotes. The list of stocks can be found in resources/data/symbols.dat.
