Volume Rate of Change

The percentage change in trading volume of a security over a period of time. For example, if 10 million shares trade on Wednesday and only five million trade on Thursday, the volume rate of change is -50%. The volume rate of change may determine how likely a price trend is to be sustained; that is, the higher the volume is, the more likely it is that a price change will become a trend.

The volume change rate (VCR) was calculated using the following equation:
Fig.2 shows the NBR samples' volume change rate (VCR) variants in crude oil at different temperatures.
Increasing acrylonitrile content had the following effects: VCR declined; with increasing temperatures, the VCR of N18 and N26 rubbers increased linearly, but the N26 change was smaller; for N41 rubber, the volume change rate slightly decreased; tensile strength increased; tensile fracture permanent deformation decreased; with the increase in temperature, the tensile strength and the tensile fracture permanent deformation of all three NBR rubbers decreased; the force of interaction between molecules enlarged.
