Hi Bonehead - I know what your saying and it does happen at times - The list below are the only seats traded derivatives in the transparent market so I dont know what is happening in the artificial markets.
I bought some of the CDUKRB for a day trade when CDU was $3.83 - If you buy minis the market maker buys the heads if you sell minis the market maker sells the heads - the spread is either 1c or 1.c usually but depends on market depth.
Cheers Hoot
