Hi Redbaron,
If he really was a spoofer and not just a large order hoping to tempt someone into filling him then by showing it on the bid side he would have been accumulating a short position that would have realised profit when the order was pulled. You don't need to expect huge reversals. 1000 lots is not particularly big in the bund most of the time spoofers are only looking for a couple of ticks profit. The best setups are when they put the fake size on the best bid or offer, when they put it a few prices away they tend to be wannabe spoofers that are so worried about getting filled on their order they hide it further down the book. The upside for them is they are less likely to get filled, but also less likely to bully the market effectively.
I've actually put together a website selling videos of me showing how I trade them. But worry about listing it on here as I don't know if it is allowed. But if you're interested just send me a PM and will show you the link.
