Status & Priority Rules

Status:

At any given time, an order is currently in one of the following states:

• Filled

• Cancelled

• Expired

• Partially Filled

• New

• Rejected

• Suspended (not currently on the order book, for example, parked Stop/Stop Limit)

Amendments:

After entering an order into the system, you can change the following properties:

• Quantity

• Disclosed Quantity

• Price

• Stop Price

• Expiration Time (GTTs)

• Expiration Date (GTDs)

Priority Rules:

When matching, the priority order (from highest to lowest) for any given price level is:

• All displayed orders

• Non-displayed parts of Icebergs (via replenishment)

• Fully Hidden Orders

• Pegged Orders

The order is then prioritized according to when it was added to the book or changed. If an order is changed, it loses priority.
