The term “Best-bid-offer” (BBO) is used to describe the highest bid and lowest ask prices shown in the order book at any time for the spot market. It helps in setting Limit and Stop-Limit orders prices to match the best current market rates. 

When traders place Limit and Stop-Limit orders, they specify the price they're able to pay or accept. These orders will only go through if the prices match what others in the market are willing to accept. The BBO is useful because it helps traders quickly find and set the best prices to fill their orders fast.

Please note: you can place an order on our platform on our website. For detailed instructions, please use the corresponding article: How to place an order from the site.

Using the BBO when placing a Limit or Stop-Limit order means the system automatically finds and uses the best market price for the order. This is especially helpful in markets where prices change quickly, as it ensures traders get the best possible price without having to keep a constant watch on the order book.

Best Bid Offer price calculation is based on:

• The side of the order to be created
• Option for BBO selected — counterparty or queue

Main features of the BBO

Best Bid Price: This is the highest price someone is willing to pay to buy a certain amount of an asset. It's the top buying price listed in the order book and usually a good deal for sellers.

Best Ask Price: The best offer, or 'ask,' is the lowest price at which someone is willing to sell a specific quantity of an asset. It's the lowest selling price in the order book and typically offers the best deal for buyers.

Types of Best Bid Offer available on our platform

Two types of the Best Bid Offer price options are available in both our mobile application & web version of our exchange:

1. “Counterparty” (opposite order-book side price) which implies that the best price should be selected from the opposite side of the order-book — from the buy order-book side for sell orders and vice versa
2. “Queue” (same order-book side price) which means that the best price should be selected from the same side of the order-book — from the buy order-book side for buy orders and from the sell order-book side for sell orders.

Please note: our platform also offers Multi limit order, which helps improve your trading experience and automate your strategies. Please find out more about this feature in our article.
