Order book vs trade book

Order book is the term used to describe a list of buy/sell orders for any security or financial instrument. This list is either manual or electronic, but in the world of online trading it is an e-list. Every time an order is placed, all order details, including price and quantity, are recorded in the order book. Each order is also assigned a specific number so as to refer to it in the future. The order book gets real-time updates. The status of an order can be ‘requested’, ‘queued’, ‘ordered’, ‘executed’, ‘part executed’, ‘expired’, ‘cancelled’ or ‘rejected’.

When an order gets executed, it enters the trade book. There is a trade number assigned and the status of the execution is also listed in the trade book. The trade book is also, like an order book, used in equity and F&O trading.

The primary difference between order book and trade book is that the order book is a reflection of all the orders that have been placed while the trade book is a reflection of the trades that have actually been executed.

If there is a partial execution then the trade book registers the extent of execution.
