Overview

Market abuse encompasses illegal activities that undermine market integrity. Understanding these practices is essential for both compliance and identifying manipulation.

Market Manipulation

Spoofing

Placing large orders with intent to cancel before execution

         buy at lower price, then cancel sell orders

Penalty: Criminal charges, fines, imprisonment

Layering

Multiple orders at different price levels
Designed to create artificial market depth
Similar to spoofing but with more complexity

Wash Trading
