# Spoofing

*Trading & Technical Analysis — Finicade finance glossary*

Spoofing places large orders with no intention of executing them, to create a false impression of supply or demand, then cancels once the price moves. It became explicitly illegal in the US under Dodd-Frank and has produced criminal convictions, including of a trader whose home-based spoofing was linked to the 2010 flash crash. It's detected through cancellation rates rather than through individual orders.

**Also known as:** layering, spoof orders
