Narrow range price bars on rising volume

Hi Pat, I have a question related to range of price bars and volume. If you look at $G from 08/17 until 08/19 price bars get narrower, but volume is picking up. First, I thought it is accumulation, but finally the stock broke down, so it could have been distribution as well. What are your thoughts on this pattern ? Always grateful for your answer. Thanks to you and Owen, TJ
