Custom OCO/OSO Orders
Placing a custom OCO and OSO order allows you to group conditional orders with multiple symbols using your own combination of OCO, Bracket OCO, and OSO orders. There is no limit to the number of parallel orders in an OCO group of orders. When any one of them is filled, the others in the group are canceled.
Access using the OCO/OSO button from the Trade Bar, and select Custom OCO/OSO Order. The Custom OCO/OSO Order dialog is displayed.
OCO Order (Order Cancel Orders) 
An OCO (Order Cancels Order) order consists of a group of two or more parallel orders that are linked together in such a way that if one of the orders is filled, then all of the other parallel orders are canceled.
For example, let say that an OCO order consists two orders; 1) a limit order to buy 500 shares of one symbol and 2) a stop order to sell 200 share of another symbol. If the limit price of #1 is hit and fills, the stop order #2 is automatically canceled.

OSO Order (Order Sends Order)
An OSO (Order Sends Order) order consists of a primary order that will send one or more secondary orders when the primary order is filled.
For example, there is an OSO order consisting of three orders. The primary order 1) is a limit order to buy 1000 shares of a symbol, and attached to it are two other orders: 1) a limit order to buy 500 shares of another symbol in the same industry and 2) an stop order for 1000 share of the primary symbol at a price .25 below the limit price for that order. When the primary order is filled, the two additional OSO orders are sent, one that buys additional shares of a related symbol and another that sets a stop loss for the primary symbol.

- Enter a symbol for the first order row.
The background of this row is white until more OCO rows are added at which point the OCO rows will have a yellow background. - Enter additional symbols to create more OCO rows. An OCO order needs to have at least two parallel rows (at the same indent level).
