Parameters | |
requestId |
The identifier of the successfully completed request. A session object may send multiple requests
(see the O2GSession.sendRequest method).
The method receives notifications of all the requests that have been successfully completed. To make sure you are getting
a notification
about a particular request, check whether or not the value of this parameter matches the value obtained by calling the
|
response |
The response object. The type of the response depends on the type of the request. For example, if you request information about open
positions, the type of the response is O2GResponseType.GetTrades. For a complete

Details
In order to process a notification about a successful request completion, an instance of the class implementing the IO2GResponseListener interface
must be subscribed to a session object.
It is accomplished by calling the O2GSession
.subscribeResponse
method.
Note: For the order creation request, successful completion means that an order has been validated by the trading server and accepted for execution. It does not mean that the order has been actually inserted in the Orders table.
The order can be rejected if it has been successfully inserted in the Orders table. In case the order is deleted, the order status is \'R\'. The rejected amount is contained in the order amount field. The rejection message is inserted to the Messages table. The rejection message has the "Market Conditions" type(feature). The message text contains the OrderID. The order delete and the reject message notification can be received randomly.
To make sure that the order is inserted to or deleted from the Orders table or the message is inserted to the Messages table, use the following methods:
