Currency strength is a popular indicator used by Forex traders to make sense of price moves in the Forex market. It takes advantage of price correlation between various Forex pairs. Currency strength is measured for 8 currencies (USD, JPY, EUR, GBP, AUD, NZD, CHF & CAD) and is reported on a scale of 0 (weakest) to 10 (strongest). Currency strength data provides the trader with important insights into the forces at play causing a move on a particular Forex pair. For example, if GBP/USD suddenly trends upwards following an economic news announcement (e.g. US Non-Farm Payroll), the currency strength values would immediately indicate whether the move was due to generalized GBP strength or USD weakness.
