Possible values: 'tick', 'minute', 'hour', 'daily', 'weekly', 'monthly', 'quarterly', 'yearly'
In get_timeseries(), the possible values that the parameter "interval" can take are the ones above. On the other hand, for a given RIC, not all will be available.
Let us say I want to extract historical data about the US GDP (USGDPF=ECI). In this case, 'quarterly' and 'yearly' are available, but not 'hour'.
From my jupyter notebook, how could I establish what the available intervals are?
