Just cruising thru other boards and noticed 3 unusual AH spikes up and down. UWTI about $2.00 straight up and right back down, also big volume UGAZ about $4.50 straight up and right back down, also big volume DUST about $4.00 straight down and right back up, no unusual volume There are probably more but is this deep pockets, Market Makers or autobots doing this? any thoughts on this? TIA SD
