On T&S there were those trades on fast downmove...no true 'bad ticks'.. maybe a 33k sell-order or a trader may have perhaps transposed the price for number of contracts sold...
fat finger by a large local or institution...if they have the margin and there is no confirm order...et-voila'!
if those are nake shorts..a career could be on play...now let's wait for an Eurex announcement on burst trades; dunno their policy.
Sorry, was looking at wrong contract. It does show on Reuters. 44000 contracts!! Somebody is on the hotseat!
