How to use the FRED API integration of the St. Louis Fed

The Economic Research department of the Federal Reserve Bank of St. Louis offers data access to a lot US and international time series datasets (FRED). They offer an API integration and we have already setup a new datafeed integration that you can easily pick a dataset. Just use the FRED dataset symbol and you can load the chart in WTT for your individual cycle analysis.

To use the FRED services within WTT, we recommend that you register once at the St. Louis Fed page for a free API key. However, you can use the service without registration with the integrated WTT test key. So once you start to use it frequently, please get your own API key to ensure proper data delivery to all users.
