The order book official monitors the orders and executes trades as the order specifications are reached. Order book officials are employees of the exchange and cannot trade for their own accounts. Their sole responsibility is to maintain the market for their assigned listed options, including executing orders remaining on the book. As physical trading floors increasingly give way to electronic markets and screens-based trading, the role of the OBO has greatly diminished. Today, most order books are maintained by algorithms or software developed by exchanges or trading platforms.

This process is driven by price-time priority, meaning that orders are filled based on the highest bid and the lowest ask, and when these prices overlap, the order that was placed first gets priority. For instance, if there is a large imbalance between buy orders and sell orders, it may indicate a stronger move in the stock. Traders can use the order book to help identify potential support and resistance levels for a stock. A large group of buy orders at a particular price may indicate a support level, while a large number of sale orders at or near the same price may indicate an area of resistance. These are the best and most competitive prices for those who are buying and those who are selling, respectively.

The reporting process for off-book trading is not as rigid as trading directly into an order book and there are fewer time constraints. Crypto exchanges set this, as a rule, to make sure that their users are always getting the best trades at any time. Assume an investor wants to buy an option contract in Apple Inc. (AAPL). Assume AAPL stock is trading at $220, and the investor wants a call option that expires in 2.5 months with a strike price of $220. The current bid for the option is $10.65 while the current offer is $11.10. Gaps or large price jumps in the order book can also provide crucial information.
This dynamic nature is fundamental to their role in the marketplace, ensuring that traders have access to the most current information.

The trailing stop will sell your position if the price reaches $900, but if the price reaches $1,100, the new trailing stop will be $990 (10% below the $1,100).
