Explained: Ladder DOM
Depth of Market
What Is Depth of Market (DOM)?
Depth of market (DOM) is a measure of the supply and demand for liquid, tradeable assets. It is based on the number of open buy and sell orders for a given asset such as a stock or futures contract. The greater the quantity of those orders, the deeper or more liquid, the market is considered to be.
Depth of market data is also known as the order book since it consists of a list of pending orders for a product. The data in the book is used to determine which transactions can be processed.
Below is an example of the ETHUSDT book we configured in the Ladder Header example.
Ladder Specification:
Orders: This column depicts the open orders you have placed onto the ladder via the How To: Place Limit Orders example. Here you can see that we have a limit order to BUY 0.01 ETHUSDT at a price of $1971 and a limit order to SELL ETHUSDT 0.01 at a price of $1986. These orders can be cancelled by clicking on the chosen order in the order column.
Bid: Shows the current bids in the orderbook, these are shown downwards from the midprice of $1979. This column also shows flagged prices as set by the 'Flag' configuration in the Ladder Header example. To place a limit or market order please refer to the relevant How To guides.
Price: Shows the price ladder for ETHUSDT at the 'step' increment set in the Ladder Header example. At the midprice you can see a line that will recenter at the discretion of the 'time' ladder header setting. In this example every 30 seconds the ladder will recenter its view and place the line back at the midprice.
Ask: Shows the current asks in the orderbook, these are shown upwards from the midprice of $1979. This column also shows flagged prices as set by the 'Flag' configuration in the Ladder Header example. To place a limit or market order please refer to the relevant How To guides.
Last: Shows the last traded price and quantity for ETHUSDT. In the below example the last trade for ETHUSDT was a BUY of 0.009 ETH.
