An order book is the list of orders that einax uses to record the interest of buyers and sellers in a particular financial instrument. Each column in order book represents how much tokens being bought or sold for the set price. Orders, that was successfully added and appeared in the order book are called market makers.

Einax user interface displays the order book as 2 vertical tables with 3 rows each. The top table represents orders of einax users willing to sell tokens for liquidity (colored Red) and Bottom table represent users willing to Buy tokens (colored Green).

Orders scheduled for execution use time/price priority meaning that sell orders with the lowest price and buy orders with the highest price will be prioritized for execution before any other orders. If two orders have the same price, the one that was placed first will be executed first.

Please keep in mind that order book displayed in a web application is refreshed every second. However, trades and other events that can change order book (like order cancelations, partial fills et c.) can occur much more frequent. Therefore order book, displayed in web application must be treated as a visual reference and using exact numbers from order book to place your order does not guarantee that your order will be executed in exact accordance to it (especially in more active markets). While placing your orders you should always make sure that your order represents your actual wish to trade. Users are fully responsible for orders, executed on their behalf.
