An OCO order lets you set two stop orders at the same time on the same market. Each leg has its own stop price, side and order type. The first leg whose trigger is crossed is placed as an order, and the other leg is cancelled. You can use it to trade a breakout in either direction, to buy below or sell above the current price, or to bracket an open position with a take profit and a stop loss.
OCO order form with Breakout, Retracement and Bracket exit presets, two legs with stop prices, trigger condition and amount

BTC OCO form with two alternative stop orders. The first to trigger cancels the other.

​
How it works

  1. Pick a preset or configure the two legs by hand.
  2. For each leg choose Stop Market or Stop Limit, Buy or Sell, and a Stop Price (plus a Limit Price for stop limit legs).
  3. Choose the Trigger Condition price source shared by both legs: Mid or Mark.
  4. Enter the Amount. Both legs use the same size.
  5. Pacifica watches the market. When one leg’s stop price is crossed, Pacifica submits that leg and cancels the other. A stop market leg places a market order using your Max Slippage. A stop limit leg places a GTC limit order at its limit price.
If both conditions are met in the same evaluation, Leg 1 takes priority.
The other leg is cancelled when the first leg triggers, before a fill is confirmed. If the triggered order is rejected or does not fill, the cancelled leg does not become active again.

​
Presets

The three buttons fill in both legs 5% away from the current mark price. Edit any field afterwards.

Example

You are long 0.1 BTC at $100,000. You want to take profit at $105,000 and stop out at $95,000:
  • Choose Bracket exit, then set Leg 1 to Stop Limit Sell with Stop Price and Limit Price both at $105,000. Set Leg 2 to Stop Market Sell with Stop Price at $95,000.
  • Set Amount to 0.1 BTC, Trigger Condition to Mid and Reduce Only on.
  • If mid reaches $105,000 first, a limit sell at $105,000 is placed and the stop loss is cancelled. If mid falls to $95,000 first, a market sell is placed and the take profit is cancelled. Either order may fill partially.

​
Good to know

  • Only the triggered leg becomes an order. Until then an OCO holds no place in the order book queue.
  • A stop limit leg rests as a GTC limit order after it triggers. If the market moves through the limit price, it may not fill.
  • Open OCOs appear under the Strategies tab (OCO sub-tab). After a leg triggers, the resulting order appears in Open Orders or Trade History.
  • OCO stop legs use Mid or Mark as the trigger source. Last trade price is not available for OCO.
