IB Bulletins

From time to time, IB sends out important News Bulletins, which can be accessed via the TWS API through the IBApi.EClient.reqNewsBulletins.

•             client.reqNewsBulletins(true);

•         client.reqNewsBulletins(true);

•         client.reqNewsBulletins(True)

•     m_pClient->reqNewsBulletins(true);

•         self.reqNewsBulletins(True)

Bulletins are delivered via IBApi.EWrapper.updateNewsBulletin whenever there is a new bulletin:

•     public class EWrapperImpl : EWrapper 
      {

  ...

          public virtual void updateNewsBulletin(int msgId, int msgType, String message, String origExchange)
          {
              Console.WriteLine("News Bulletins. "+msgId+" - Type: "+msgType+", Message: "+message+", Exchange of Origin: "+origExchange+"\n");
          }

• public class EWrapperImpl implements EWrapper {

  ...

      @Override
      public void updateNewsBulletin(int msgId, int msgType, String message, String origExchange) {
          System.out.println("News Bulletin: " + EWrapperMsgGenerator.updateNewsBulletin( msgId, msgType, message, origExchange));
      }

•     Public Class EWrapperImpl
          Implements EWrapper

  ...

          Public Sub updateNewsBulletin(msgId As Integer, msgType As Integer, message As String, origExchange As String) Implements IBApi.EWrapper.updateNewsBulletin
              Console.WriteLine("News Bulletins. " & msgId & " - Type: " & msgType & ", Message: " & message & ", Exchange of Origin: " & origExchange)
          End Sub

• class TestCppClient : public EWrapper
  {

  ...

  void TestCppClient::updateNewsBulletin(int msgId, int msgType, const std::string& newsMessage, const std::string& originExch) {
      printf( "News Bulletins. %d - Type: %d, Message: %s, Exchange of Origin: %s\n", msgId, msgType, newsMessage.c_str(), originExch.c_str());
  }

• class TestWrapper(wrapper.EWrapper):

  ...

      def updateNewsBulletin(self, msgId: int, msgType: int, newsMessage: str,
                             originExch: str):
          super().updateNewsBulletin(msgId, msgType, newsMessage, originExch)
          print("News Bulletins. MsgId:", msgId, "Type:", msgType, "Message:", newsMessage,
                "Exchange of Origin: ", originExch)

In order to stop receiving bulletins you need to cancel the subscription:

•             client.cancelNewsBulletin();

•         client.cancelNewsBulletins();

•         client.cancelNewsBulletin()

•     m_pClient->cancelNewsBulletins();

•         self.cancelNewsBulletins()
