Final answer:
Order book officials can accept various types of options orders including limit orders, stop orders, market orders, as well as complex orders like spread and straddle orders, all based on exchange rules.
Step-by-step explanation:
An order book official is typically responsible for maintaining a fair and orderly market for options traded on an exchange. The types of orders that may be accepted by an order book official vary depending on the rules of the exchange but often include limit orders, where the trade is executed at a specific price or better; stop orders, which trigger a sale or purchase when a certain price is reached; and market orders, which are executed at the best available price. These officials may also handle more complex orders, such as spread orders, where multiple options are bought or sold in a predetermined ratio, and straddle orders, which involve buying or selling a pair of contracts for the same stock.
