Only about 30mm stayed on the ask over night, whic

Only about 30mm stayed on the ask over night, which means a lot of these orders are day orders and not GTC orders.  MM's should keep at least a placeholder amount for GTC orders even if they don't show the true size.  This suggests to me that folks are just testing the ask (i.e. they want out, but not that badly).  This is my opinion.
