From the perspective of the components in the cross correlation, the high frequency part and high frequency, low frequency part and the low frequency part, trend and trend presents a pro-cyclical changes, there is a very strong lead lag relationship, for a period of time (60 minutes), and sustained strong influence each other, but with the extension of the time lag correlation leading gradually reduced.
