no reason to be upset. here is a really strange thing: about 3 yrs. ago i saw a really heavy thing in the DAX. the contract is (was) about 2.5 times the MiniSP in weight, and some guy or firm tried to play with two orders: buy 9999 contract, sell 9999 contracts (you cannot enter more via an EUREX terminal), with about 3 points in "spread". i think what these guys tried was to lock the futures market - and therefore the cash along - in a tight range, while being the market maker and earning the spread. he played for some minutes, never came back. i remember this one well... regards
