An order book lists open buy and sell orders on an exchange. Traders read that list as a signal of where price is heading. A spoof changes what the list seems to say. When the fake order goes away, price can snap back.
What is spoofing?
Spoofing is market manipulation. Someone places an order with no plan to let it trade. It sits in the book long enough to be seen, then gets canceled. The aim is a false picture of supply or demand.
How does spoofing work?
The spoofer posts a large order on one side of the book. Other traders see it and may assume price will move away. Before the fake order can fill, the spoofer cancels it. Then a real order on the other side fills at the pushed price.
- Post a large order on one side
- Let other traders see it
- Cancel it before it fills
- Fill a real order on the other side
How does it affect traders?
Spoofing can create false liquidity. The book looks deep, so a trader may expect an easy fill. When the fake order vanishes, that support or resistance disappears. Price can swing suddenly, and resting orders may fill at worse levels.
How is it different and regulated?
Layering uses several fake orders at different prices. It builds a false ladder of depth. Wash trading fakes volume through trades. In the US, spoofing is banned in regulated futures markets under the Commodity Exchange Act. Crypto exchanges usually ban manipulation, but enforcement varies by platform and country.
