Combination Order refers to 2 Leg and 3 Leg orders. ‘Combination Order’ allows the user to enter 2 or 3 IOC orders simultaneously in two or three different contracts of the same or different underlying with the purpose that the entered multiple orders get matched either fully or partly but in Order Quantity proportion in which these contracts are entered in Combination Order entry.

The fully or partly unmatched Combination orders get cancelled immediately. Each combination order gets converted into 2 or 3 normal orders depending upon the legs entered. All the Leg1, Leg2 and Leg3 orders shall have different order numbers and a Common Distinct Reference Number for each leg to identify that these orders have been generated through a Combination Order. Each leg contract must be a different contract.
