Valueflow Alpha Vantage

Description

This is a Valueflow module to manage and download financial data from the awesome Alpha Vantage API.

Usage

Setup

Obtain an API key from Alpha Vantage then copy that to the API Key setting.

Add symbols

To be able to download a certain data set you will need to add some mapping in the settings.

For example to add an USD->EUR mapping:

  • Source: USD (local source name)
  • Target: EUR (local target name)
  • AV Symbol: EUR=x (Alpha Vantage symbol for the exchange rate)

Please inform about AV symbols at their documentation but basically it is pretty similar to the well known former Yahoo Finance API. Symbols for US stocks are usually just the ticker (IBM, AAPL etc), prefixed for other exchanges (e.g. FRA:symbol for Frankfurt) and USD->Something marked as SOMETHING=x.
