====== OCO ======

An **OCO** (One Cancels Other or Order Cancels Order) consists of a:

  * Buy limit order **below** the market and a buy stop order **above** the market, **or**
  * Sell limit order **above** the market and a sell stop order **below** the market.

When one order is filled, the other is automatically canceled.  
If one order is partially filled, the remaining volume on the other order is reduced accordingly.

===== How to Enter an OCO =====

  * Left-click on the **OCO** option — the color will turn **orange** to indicate it is active.
  * Two blank boxes will appear under the order types:
    * One labeled **L** for limit
    * One labeled **S** for stop

===== Managing OCO Orders =====

  * If one side of the OCO is filled, the other side is canceled automatically.
  * To cancel both orders manually, simply click on one of them — both will be canceled together.

===== Verifying OCO Orders =====

You can confirm and monitor your OCO orders in the **All** or **Working** tab of your **Order Book**.
