📈Orderbook, Order Types, Fees


The orderbook is LN Exchange’s primary edge in the context of a performant trading engine. Liquidity is augmented as positions from pairwise LP markets populate the orderbook.

Limit orders are placed on the book and held in the bids and asks fields of the Market. Orders are matched by price-time priority: orders are executed based on the best price, and if multiple orders are at the same price, the order with the earliest time will be matched first.
