The user suggests two methods for creating an order book: generating multiple buy and sell orders in ascending order or creating a large buy/sell order and analyzing the resulting metadata. They believe the order book created with the Simulate command will be robust and adaptable for future enhancements to the payment engine. The user seeks confirmation from developers regarding the feasibility of this approach with the simulate command.
