All Handler classes are located in the Onixs.Cme.DropCopy namespace.

The recommended process for using Handler is as follows:

1. (Optional) Configure Handler properties that are common for all Handler instances using the static properties of the Handler class.
2. Create the Handler object.
3. Subscribe to the relevant Handler events.
4. Start Handler using the Logon(String, Int32, String, String) method.
5. Process the received market data that are reported via Handler events arguments.
6. Stop Handler using the Logout() method.
