Remove Orders from Existing Contingency Group

You can remove one or more orders from an existing contingency (OCO, OTO or ELS) group.

To remove orders from a contingency group:

1) Create an O2GValueMap and fill only one field:

Valuemap field

Datatype

Description

COMMAND

String

The command. Must be RemoveFromContingencyGroup.

The field is obligatory.

2) Create an O2GValueMap for each order you want to remove from the contingency group. Fill these value maps as

Valuemap field

Datatype

Description

ACCOUNT_ID

String

The identifier of the account which the order belongs to.

The field is obligatory.

ORDER_ID

String

The identifier of the order to be removed from the group.

The order must exist, must be an entry order (LE or SE) and must be in the Waiting status.

The field is obligatory.

COMMAND

String

The command. Must be RemoveFromContingencyGroup.

The field is obligatory.

3) Append each entry order valuemap to the main valuemap using the O2GValueMap.appendChild method.

Please note that only dependent orders may be removed from OTO or ELS groups.

4) Pass the main valuemap table to the createOrderRequest method.

Limitations:

All entry orders must be created for the same account.

Returns:

The createOrderRequest method will return an O2GRequest (the main request) containing child requests. If 2 entry orders are removed, 2 child requests will be returned. Note that you will receive responses to the child requests and will not receive a response to the main request.

Example: Remove orders from an existing contingency group [hide]

    public void removeFromGroup(String sAccountID, String sSecondaryID1, String sSecondaryID2)
    {
        O2GRequestFactory factory = mSession.getRequestFactory();
        if (factory == null) {
            return;
        }
        O2GValueMap valuemap = factory.createValueMap();
        valuemap.setString(O2GRequestParamsEnum.COMMAND, Constants.Commands.RemoveFromContingencyGroup);
 
        // secondary order
        O2GValueMap valueRemove = createValueMapForExistingOrder(sSecondaryID1, sAccountID);
        valueRemove.setString(O2GRequestParamsEnum.COMMAND, Constants.Commands.RemoveFromContingencyGroup);
        valuemap.appendChild(valueRemove);
 
        // secondary order
        valueRemove = createValueMapForExistingOrder(sSecondaryID2, sAccountID);
        valueRemove.setString(O2GRequestParamsEnum.COMMAND, Constants.Commands.RemoveFromContingencyGroup);
        valuemap.appendChild(valueRemove);
 
        // create request from valueMap
        O2GRequest request = factory.createOrderRequest(valuemap);
        mSession.sendRequest(request);
    }
 
    public O2GValueMap createValueMapForExistingOrder(String sOrderID, String sAccountID)
    {
      O2GRequestFactory factory = mSession.getRequestFactory();
      O2GValueMap valuemap = factory.createValueMap();
      valuemap.setString(O2GRequestParamsEnum.ORDER_ID, sOrderID);
      valuemap.setString(O2GRequestParamsEnum.ACCOUNT_ID, sAccountID);
      return valuemap;
    }
