The available symbols for a specific connection are determined by the connecting API. MotiveWave will populate the local database with an initial set of symbols. If the symbol that you require is not on the list, you can try searching for it by clicking on the magnifying glass symbol found in the upper left hand corner of the platform. You can then pull the symbol from the search results. Here is an example showing a search for USD with the Kraken connection. Notice all the returned results.
If the symbol does not show there then you can always try mapping it via the Configure > Instruments menu and clicking on the Define button.
