A market-on-close (MOC) order is an order to buy or sell a security at the closing price of the trading day, as close as possible to the market's official close. These orders are typically used to execute trades at the end of the day, often to capitalize on potential price movements or to manage risk associated with holding positions overnight.

To place an MOC order, click the dropdown arrow in the toolbar of the contract window and choose “Market on Close”.

Note:

• The MOC button will not be visible after the market closes or halts for the session. It will reappear when the market enters “PreOpen” for the next session.
• The close time used is the electronic close time, not the pit close time.

In the MOC setup box, you can configure:

• The number of seconds before market close to submit your first order.
• The number of seconds before market close to submit your last order.
• The number of orders your MOC will be split into.

For example: If you submit a 6-lot order and split it into 3, it will place three separate 2-lot orders at the configured intervals.

After configuring your settings, click OK.

• Choose the quantity of each order using the “L:” box.
• Confirm the MOC settings.
• To place the order:
  • Click in the Bid column to buy.
  • Click in the Offer column to sell.

• You will not see MOC orders in the “My B” or “My O” columns.
• These orders are held on the server until their activation time.
• You can view them in the Order Book under the “All” or “Held on Server” tabs.

To see the time each MOC order will enter the market:

• Add the “Activation” column to the Order Book via the Properties.
• Each order in the batch will show its individual activation time.

(For example: a batch of 3 orders may show activation times 5 seconds apart.)
