changes in names of the users of user ID, especially when there are changes in the users Notes
who are dealing on behalf of the trading member.
3. Password: When a user logs in for the first time, he has to enter the default password
‘NEATCM’ provided by the exchange. On entering this password, the system requests the
user to enter a new password in the `New Password’ field. On entering the new password
the system requests for confirmation of this new password. This new password is known
to the user only.

Box 5.1: Features of User ID and Password
Location Specific User ID: Earlier, it was possible for the members having connectivity at
more than one location to use the allotted user IDs interchangeably from either location.
This gave rise to various systems security related problems. To reduce such potential risks
associated with the member’s workstation, the exchange assigns user ID to a specific
location. So, whenever a user attempts to log on to the trader workstation, the system
checks for a valid location for that user ID in the database at the host end.
Password:

The password should contain minimum of six characters and maximum of eight
characters in length. A combination of characters and numbers is allowed in the
password.

The password can be changed if the user desires so and a new password can be
entered. The new password must be different from the old password.

Password appears in the encrypted form and thus complete secrecy is maintained.
The system ensures the change in password for all users (password expiry period is
parameterized by the exchange).

In the event of the user forgetting his password, the trading member is required to
reset the password from his corporate manager user id. In case the corporate manager
id is disabled then he is required to inform the exchange in writing, requesting to
reset the password. The user password is reset to the default password set by the
exchange. The user can login by entering a new password as per the procedure
outlined above.
• When a user tries to login with a wrong password a message ‘Invalid Sign on’ is
displayed. If three attempts are made by a user to log on with an incorrect password,
then that user is automatically disabled. In case of such an event, the trading member
is required to reset the password from his corporate manager user id. In case the
corporate manager id is disabled then he is required to makes a written request to
the exchange for resetting of password. The user password is reset to the default
password set by the exchange. The user can login by entering a new password as per
the procedure outlined above.

5.2.5 Log Off/Exit from the Application

One can exit from the application as and when one desires before the surcon period. On invoking
the log off screen, the following options are displayed to the user.

1. Permanent Sign Off: As the name suggests, a user can log off permanently from the
trading system by selecting this option. The user is logged off and the log on screen
appears.
2. Temporary Sign Off: Temporary sign off is a useful feature that allows the user to disallow
the use of the trading software without actually logging off. During a temporary sign-off
