Could you get infinite volume at a price...?! I recall an instance at my old HF firm when we took down Liffe for 30 seconds or so after two of our stratgies simultaneously sent thousands of messages (caused by some faulty C+ code)... Fortunately we didn't get any fills on our orders, but it made me wonder...

But it's weird that you could get so many orders and not move the markets. I don't know how you could get 2 competing algos that wouldn't move the markets by more than 1 tick. Very rarely can you get weird interaction between two sets of computer code and not see the results move exponentially towards some drastic result, ie. positive feedback loop to infinity. As someone else mentioned, the flow was completely orderly, so whatever they were doing, the buys and sells were exactly matched. It doesn't seem like they were picking off anyone else's orders as well, otherwise it would have moved the markets bigtime. What if they weren't match orders though? Financial catastophe?
So you guys could stop guessing...

Yes....already looked at the days data run. I will see what the CME shows latter here............. http://www.cmegroup.com/trading/equ...sandp500_quotes_timeSales_globex_futures.html
dude big funds and banks dont do 200k contracts at one frickin price guy. No one does. AND block trades in the Eminis is illegal.
yeah really, the rules are too vague, what really is a block trade? Placing orders larger then the book depth or what?
