I see the MM's decided to put a stop to the volume today. bid and ask at 20 x 30. Nice spread. How in the world can the MM's think after all this volume that they should spread the price out so much. UW, sorry to be complaining so much today, but this has been the most frustrating I have ever been on how MM's do their job. They get a flat out "F" for a grade today. Its disgusting, especially the manipulating up and down and up and down today, with the most changes on minor trades.
