One-Cancels All (OCA) order type allows an investor to place multiple and possibly unrelated orders assigned to a group. It’s designed to allow investors to submit several orders aimed at taking advantage of the most desirable price within the group. Completion of one piece of the group causes cancellation of the remaining group orders while partial completion causes the group to rebalance.
The endpoint /iserver/account/{accounted}/orders can be used to pass order request info in an Array by setting isSingleGroup to true in each order. All orders in the same group will be assigned the same oca_group_id. After the orders are successfully placed, send the endpoint /iserver/account/order/status/{orderId} to receive the oca_group_id.
