My theory, based upon conspiracy, is that those are not real trades involving UNGS shareholders. My theory is based upon the pattern of the trades. The latter trades appear to be coordinated in 3s within close time periods. A Red trade occurs when someone sells to a Bid. A Green trade occurs when a someone buys from the Ask. What it means to me is that the MMs made all of the trades today. Why? Sorry, I don't have all of the answers. Perhaps, a Whale can enlighten.
