BREAKING DOWN 'Price By Volume Chart  PBV'
Large price by volume bars are used to illustrate high buying and selling interest, and they are often regarded as a sign that the given price level will act as a strong area of support or resistance. It is common to see the price of an asset face little resistance when traveling between levels that have small PBV bars, but pushing the price past areas with large PBV bars is substantially more difficult.
