Before revision:  This study, by applying the MF-DXA method , demonstrates that priceand trading volume and their coupling contain power law information and are multifractal in the markets we investigated. Also, the resultant correlation coefficients present scaling behaviors which are totally significant in the investigated time-scales and they decrease with increasing time-scales . Meanwhile, considering developed markets, the price-volume coupling is more dominated by trading volume rather than price.
