Positive or negative correlation

This depend upon the direction of series. If both variable are increasing or decreasing in same direction than this is positive correlation and if they are varying in opposite directions then they are having negative correlation. If one series is increasing and other is also increasing and if one is decreasing and other series is also decreasing then this is positive correlation and if one series is increasing and other is decreasing and if one is decreasing and other is decreasing they this is negative correlation.
