The forward rates are supposed to be used by institutionals in order to know what will (should) be the trend in the future.
Euro Dollar Forward Rates | EUR USD Forward Rates
Here we have for example :
EURUSD ON FWD -0.3000
EURUSD SN FWD -0.8100
ON, that means that EU will lose 30 pips between tonight and tomorrow.
SN, means that EU will lose 81 pips between tonight and the day after tomorrow.
It can be used as an indicator.
Note : it doesn't take into consideration the economic news and their theoretical impact.
