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 a sell limit order above the market and a sell stop order below the market. When one gets filled the other is cancelled. If one is partially filled then the volume on the other is reduced accordingly.
An OCO Order is submitted with the
New Order List (Tag 35=E) message.
Following are the most relevant tags to build an OCO order.
| Tag 1385=1 | ContingencyType | Specifier of OCO order type |
|---|
| Tag 44 | Price | Price of Limit component of OCO. Must be below last traded price for Buys and above for Sells.
|
|---|
| Tag 99 | Stop Price | Price of Stop component of OCO. Must be above last traded price for Buys and below for Sells.
|
|---|
| Tag 48 | SecurityID | Market for which the order is sent |
|---|
| Tag 55 | Symbol | Contract for which the order is sent |
|---|
| Tag 207 | SecurityExchange | Exchange for which the order is sent |
|---|
OCO orders can also be GTC's, StopLimit or Trailing. Activation is not supported with OCO orders. The Limit component of the OCO can be specified as either a Limit (Tag 40=2) or a Market-if-Touched (Tag 40=J) order type. Please note that OCO's are not intended to be used where both orders are very close together, for example at consecutive prices or at the best bid and best offer prices. For this scenario, it is likely that both components would get filled in an active market. All components of an OCO order must pertain to the same account and market.
SampleIn this example, a buy OCO order is submitted at the Limit Component Price of 157850 (Tag 44 =157850) with a Stop Component Price of 157900 (Tag 99 = 157900). The Stop component is filled and subsequently the Limit component is canceled.
