Definition of 'Market-On-Open (MOO) Orders'

A market-on-open (MOO) order is a type of order used in financial trading to execute a trade at the opening price of a trading day for a given security.

With a MOO order, the investor places an order to buy or sell a security at the market price, which will be executed as soon as the market opens. MOO orders can be placed up to the end of the previous trading day, and are executed in the first few minutes of trading on the next trading day.

MOO orders are commonly used by traders who want to take advantage of price movements that occur at the opening of the market, when there is often a surge in trading volume and price volatility. This type of order is also useful for investors who want to avoid the uncertainty of placing an order during the trading day, where the market prices can fluctuate rapidly.

However, there are also risks associated with MOO orders. The price of a security can change significantly between the time the order is placed and the market opens, resulting in a trade execution at a price that is significantly different than the investor's intended price. Additionally, if there is a large volume of MOO orders for a particular security, it can result in increased price volatility and wider bid-ask spreads. As with any trading strategy, it is important for investors to carefully consider the risks and benefits of using MOO orders and to use them in a disciplined and informed manner.
