Trading Session Rule of Condition Order

When you place conditional orders for options that support GTH or Curb sessions, the system will monitor the market price of the options across Global Trading Hours (GTH), Regular Trading Hours (RTH), and the Curb Session. If the conditional order is triggered, the system will immediately place the preset order in the session where the condition was triggered. For example, if the conditional order is triggered during GTH, the preset order will also be placed for GTH.

Note:

• If one of the price presets is set to "market price," the conditional order can only be triggered during RTH, and the preset order will be placed for RTH.
• Preset orders follow the same expiration rules as regular orders. (See Trading Session Selection for Options for details.)
