I don't know what order spoofing is, but this is slightly different from regular spoofing. Spoofing is a size game in a populated order book. This is more a cat and mouse chase in illiquid markets. It is something you almost naturally do in an empty book, and when you realize the other order has gone too far, it is tempting to take the other side. It is more in my grey area, but I choose not to do it because I don't need it and I feel it is actually manipulative if I click. Spoofing is well sanctioned since at least 2010 on the exchange, CFTC and dpt of justice level. Nowadays only chinese prop traders are so dumb to do it. They get caught, receive an hefty fine and are permanently barred from trading on Globex. If you read CME disciplinary sanctions, it feels like it's half of them.LOL
