Have you performed any correlation studies between the economic factors and the currency pairs concerned? For example, if UK interest rates rise by say 0.5%, whilst US rates remain on hold, what is the likely percent increase in the GBPUSD? Further, is there a time-lag between the interest rate rise and the GBPUSD rise?
I previously traded interest rate futures, and economic data correlation proved quite helpful in forecasting direction, range of forecast move, and timing. Would be interested in hearing from forex traders performing this analysis, and the results achieved.
