There is another ... Remember, currency correlation is presented in decimal format by a correlation coefficient, simply a number between -1.00 and +1.00. A coefficient near or at +1 indicates that the two pairs have strong positive correlation and will likely move in the same direction. In the same respect, a coefficient near or at -1 indicates that the two pairs still have a strong correlation, but a negative one ...
