We have created a new currency exchange rate extractor. This component allows you to extract currency exchange rates as published by European Central Bank (ECB). Its configuration is dead simple, all you need to do is select the source currency (USD and EUR are currently supported).
This extractor provides the same data in the same format as the old extractor (which had to be configured through support). We encourage you to switch to the new one - set it up as any other extractor. We will keep running the old extractor till January 2017. Just let us know once you don't need it, so that we can deactivate it and stop magically pushing data to your project.
Like in the old currency extractor, the resulting data contains gaps for bank holidays (including weekends). If you would like to fill the gaps with last known value, you can use a little SQL script we hacked together.
