Chapter 04 · Section 4.1

Opening Rotation Orders and Market-on-Close Orders

Opening Rotation orders are to be executed during the official opening rotation at the beginning of the trading day, or not at all.

Market-on-close orders can only be executed during the official closing session at the end of the trading day.

Open rotation orders and market-on-close orders should not be confused with opening purchase or sale orders or closing purchase or sale orders which are indicated when the words "opening" or "closing" are written in an order.
