Trade on the order books

Loopring is more than just an AMM. It is also an order book DEX. So if you rather ‘trade’ a pair on the books rather than the pool, head over to the ‘Trade’, tab at top and then select ‘Order Book’

There you will see the familiar order book layout, displaying bids and asks, a price chart, price history, etc.

Sometimes the order books has different asset pairs than the AMM pool. Especially stablecoin to stablecoin pairs.

The orderbook supports limit orders, meaning you can state the price you want to buy or sell at, and leave it resting on the books. Someone can then come along and fill your order. This way, you are guaranteed to get the price you want.

The order book also supports market orders, meaning you can buy or sell at the prevailing best ask or bid. It is important to note that when making a market order, you don’t have control over the price that you will pay — the order will fill with the best available liquidity there is.

Did you know?

Makers receive rebates on their orders that get filled on the books. The rebate is 0.02% (2 bps). So any resting limit order you have that gets taken by another user, you earn 0.02% of that amount — i.e., a negative fee! in addition to maker rebates, there is also often liquidity mining for order book pairs! This incentivizes users (especially market makers or algorithmic traders) to place tight resting limit orders on the books, and receive rewards for providing that liquidity (being a maker) for others to take.

You may also want to plug into an existing market making software that is connected to Loopring L2 DEX, such as Hummingbot!
