# Reduce Only **Reduce Only** ensures that orders **strictly decrease an existing position**, preventing accidental increases. When enabled, this safeguard helps traders **close or trim positions** without inadvertently expanding them. #### **How It Works** * The **Reduce Only instruction** is passed to the exchange on **every order slice**, ensuring that only position-reducing trades are executed. * Prevents new position openings, limiting execution to **position reductions only**. #### **Considerations** * **Not available on OKX**, as the exchange does not support this functionality. * Helps maintain **risk control** by preventing **accidental exposure increases**. This setting is useful for traders who need to **exit or scale down positions** without risking unintended position growth. --- # 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.
