# Position Average Is Changing Overnight If you hold futures positions overnight (through the 16:00 CT close) and your average position and profit/loss change, your broker account might be set as Mark-To-Market which essentially closes and reopens the trade each night for accounting purposes. Please contact your broker for more information. This cannot be controlled by MotiveWave. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
