How Should I Read the Order Book?

ZMO's order book displays all unfilled buy and sell orders in real time. Green prices are bids, red are asks — click any price to auto-fill your order.

The Order Book is where trade orders that haven’t been filled are displayed.

  • Prices in red are the current Sell (Ask) order prices

  • Prices in green are the current Buy (Bid) order prices

  • If you would like to take a price that already exists on the Order Book, you can click the Buy/Sell Price and the system will automatically fill in the price for you.

For example, in the picture above:
• The best Bid Price is: $81637.7 with .09919 contracts
• The best Ask Price is: $81655.2 with .08673 contracts

*If you are a buyer, you should check the Sell Prices at the top to see how high you are willing to buy at; if you are a seller, you should check the Buy Prices at the bottom.
