"you want to be hitting that size". Could you please clarify. Are you saying if there are, eg 10,000 on the bid, you should sell?
Re spoofs on the schatz, in my limited experience the schatz is the last place you'll see spoofs - the size of some trades is actually larger than many of the spoofs seen on the bund or bobl.
Correct you want to be hitting that size but you need to identify 2 things first. #1 be sure it is more than likely a spoof. #2 make sure it is not just flashing but the order is holding for a while (trying to entice people to lean on it). Just watch the orderbook and see what happens when a big spoof sits around too long
Remember if there is a 10,000 lot bid spoofer in the schatz, there is a reason he is spoofing and not just bidding. He doesn't want to actually be long!!! So if he doesn't want to be long he wants to be flat or short (more than likely short otherwise why would you mess around with spoofing and take the risk if you just wanted to **** with people).
Hope that helps
