Anyone know what was happening with several of the Proshares? SRS, UYM, DXD, and many more were getting strange jumps on 100 and 200 share lots. I lowered my order quantity, to try and take advantage, only to see several fills at better prices for someone else. I have been only been daytrading these ETFs for a couple of months and have not seen anything like this. This was going on between about 10:10 and 10:33 today.
