Circular trading - A fraudulent trading scheme where sell orders are entered by a broker who knows that offsetting buy orders, the same number of shares at the same time and at the same price, either have been or will be entered. These trades do not represent a real change in the beneficial ownership of the security


General Cross
A practice where buy and sell orders for the same stock are offset without recording the trade on the exchange, which is outlawed on most major stock exchanges. This also occurs when a broker executes both a buy and a sell for the same security from one client account to another where both accounts are managed by the same portfolio manager.
