Yeah they are still in there, they aren't as obvious as they used to be and are a far smaller part of my trading arsenal. But last week there was a lot of spoofing in the Bund
Best to write a piece of code that monitors the DOM and logs all large orders. In that manner, you can completely quantify the spoofing activity.
This could be done using the Interactive Broker's API. There are tons of programmers out there with experience in this API.
This is pretty stupid. So let's say I put in orders half of the size of Corsica's biggest orders - then would my spoofing technique be okay. No? A quarter of the size? No? An eight of the size? No? A sixteenth of the size? ... If they are so concerned about spoofing, why don't they just require orders to stay active in the book for a few seconds. Then you enforce no spoofing by the exchange rules themselves. But no, let's waste time trying to figure out "intent" of all live orders and also waste taxpayer money to take people to court. What a joke. All because the HFTs have the regulators in their back pockets.
Most spoof orders are in the market for a few seconds at a time they need to be there long enough to look real. The fact is, if the markets allowed spoofers eventually they would be so many people spotting them and profiting from them they would become unprofitable. The only regulation that works is competition and the risk of losses.
