Login Message Flow
On a successful login, the following is the sequence of messages to expect. Note that after sending a Login Request, members should wait for both a Login Response message of Accepted as well as a Replay Complete message before sending new application messages.

| Member ← Cboe | Login Response ( A = Accepted) |
| Member ← Cboe |
