How it works
Binary Options is a financial instrument used to make profit by predicting an asset’s price movement (currencies, shares, commodities). In order to receive profit, a trader makes a prediction regarding the direction of the underlying asset’s price movement. If the prediction is correct, the trader receives profit. If it is not, the trader takes losses. Traders can also close the trade early if they realize that the prediction is not correct. In this case, a part of the contract cost is refunded.
Purchase a CALL option if you think that the price of the chosen asset will be higher than at the moment of its expiration time.
- If your prediction is correct, you will receive profit.
- If the price remains the same, you don’t take losses and don’t receive any profit.
- If the current price is lower than the price at the moment the option was bought, you take losses.
GRANT
Use the GRANT statement to grant:
System privileges to users and roles.
Roles to users and roles. Both privileges and roles are either local, global, or external. Table 18-1 lists the system privileges (organized by the database object operated upon). Table 18-2 lists Oracle Database predefined roles.
Object privileges for a particular object to users, roles, and PUBLIC . Table 18-3 summarizes the object privileges that you can grant on each type of object. Table 18-4 lists object privileges and the operations that they authorize.
Notes on Authorizing Database Users You can authorize database users through means other than the database and the GRANT statement.
Many Oracle Database privileges are granted through supplied PL/SQL and Java packages. For information on those privileges, please refer to the documentation for the appropriate package.
Some operating systems have facilities that let you grant roles to Oracle Database users with the initialization parameter OS_ROLES . If you choose to grant roles to users through operating system facilities, then you cannot also grant roles to users with the GRANT statement, although you can use the GRANT statement to grant system privileges to users and system privileges and roles to other roles.

REVOKE for information on revoking grants
To grant a system privilege, you must either have been granted the system privilege with the ADMIN OPTION or have been granted the GRANT ANY PRIVILEGE system privilege.
To grant a role, you must either have been granted the role with the ADMIN OPTION or have been granted the GRANT ANY ROLE system privilege, or you must have created the role.
To grant an object privilege, you must own the object, or the owner of the object must have granted you the object privileges with the GRANT OPTION , or you must have been granted the GRANT ANY OBJECT PRIVILEGE system privilege. If you have the GRANT ANY OBJECT PRIVILEGE , then you can grant the object privilege only if the object owner could have granted the same object privilege. In this case, the GRANTOR column of the DBA_TAB_PRIVS view displays the object owner rather than the user who issued the GRANT statement.
Use these clauses to grant system privileges.
Specify the system privilege you want to grant. Table 18-1 lists the system privileges, organized by the database object operated upon.
If you grant a privilege to a user , then the database adds the privilege to the user’s privilege domain. The user can immediately exercise the privilege.
If you grant a privilege to a role , then the database adds the privilege to the privilege domain of the role. Users who have been granted and have enabled the role can immediately exercise the privilege. Other users who have been granted the role can enable the role and exercise the privilege.
If you grant a privilege to PUBLIC , then the database adds the privilege to the privilege domains of each user. All users can immediately perform operations authorized by the privilege.
Oracle Database provides the ALL PRIVILEGES shortcut for granting all the system privileges listed in Table 18-1, except the SELECT ANY DICTIONARY privilege.
Specify the role you want to grant. You can grant an Oracle Database predefined role or a user-defined role. Table 18-2 lists the predefined roles.
If you grant a role to a user , then the database makes the role available to the user. The user can immediately enable the role and exercise the privileges in the privilege domain of the role.
If you grant a role to another role , then the database adds the privilege domain of the granted role to the privilege domain of the grantee role. Users who have been granted the grantee role can enable it and exercise the privileges in the granted role’s privilege domain.
If you grant a role to PUBLIC , then the database makes the role available to all users. All users can immediately enable the role and exercise the privileges in the privilege domain of the role.

IDENTIFIED BY Clause
Use the IDENTIFIED BY clause to specifically identify an existing user by password or to create a nonexistent user. This clause is not valid if the grantee is a role or PUBLIC . If the user specified in the grantee_clause does not exist, then the database creates the user with the password and with the privileges and roles specified in this clause.
CREATE USER for restrictions on usernames and passwords
WITH ADMIN OPTION
Specify WITH ADMIN OPTION to enable the grantee to:
Grant the role to another user or role, unless the role is a GLOBAL role
Revoke the role from another user or role
Alter the role to change the authorization needed to access it
If you grant a system privilege or role to a user without specifying WITH ADMIN OPTION , and then subsequently grant the privilege or role to the user WITH ADMIN OPTION , then the user has the ADMIN OPTION on the privilege or role.
To revoke the ADMIN OPTION on a system privilege or role from a user, you must revoke the privilege or role from the user altogether and then grant the privilege or role to the user without the ADMIN OPTION .
TO grantee_clause identifies users or roles to which the system privilege, role, or object privilege is granted.
Restriction on Grantees A user, role, or PUBLIC cannot appear more than once in TO grantee_clause.
PUBLIC Specify PUBLIC to grant the privileges to all users.
Restrictions on Granting System Privileges and Roles Privileges and roles are subject to the following restrictions:
A privilege or role cannot appear more than once in the list of privileges and roles to be granted.
You cannot grant a role to itself.
You cannot grant a role IDENTIFIED GLOBALLY to anything.
You cannot grant a role IDENTIFIED EXTERNALLY to a global user or global role.
You cannot grant roles circularly. For example, if you grant the role banker to the role teller , then you cannot subsequently grant teller to banker .
Use these clauses to grant object privileges.
Specify the object privilege you want to grant. You can specify any of the values shown in Table 18-3. See also Table 18-4.
Restriction on Object Privileges A privilege cannot appear more than once in the list of privileges to be granted.
Specify ALL to grant all the privileges for the object that you have been granted with the GRANT OPTION . The user who owns the schema containing an object automatically has all privileges on the object with the GRANT OPTION . The keyword PRIVILEGES is provided for semantic clarity and is optional.
Specify the table or view column on which privileges are to be granted. You can specify columns only when granting the INSERT , REFERENCES , or UPDATE privilege. If you do not list columns, then the grantee has the specified privilege on all columns in the table or view.
For information on existing column object grants, query the USER_ , ALL_ , or DBA_COL_PRIVS data dictionary view.
The on_object_clause identifies the object on which the privileges are granted. Directory schema objects and Java source and resource schema objects are identified separately because they reside in separate namespaces.
If you can make this grant only because you have the GRANT ANY OBJECT PRIVILEGE system privilege–that is, you are not the owner of object , nor do you have object_privilege on object WITH GRANT OPTION –then the effect of this grant is that you are acting on behalf of the object owner. The *_TAB_PRIVS data dictionary views will reflect that this grant was made by the owner of object .

WITH GRANT OPTION
Specify WITH GRANT OPTION to enable the grantee to grant the object privileges to other users and roles.
Restriction on Granting WITH GRANT OPTION You can specify WITH GRANT OPTION only when granting to a user or to PUBLIC , not when granting to a role.
WITH HIERARCHY OPTION
Specify WITH HIERARCHY OPTION to grant the specified object privilege on all subobjects of object , such as subviews created under a view, including subobjects created subsequent to this statement.
This clause is meaningful only in combination with the SELECT object privilege.
object Specify the schema object on which the privileges are to be granted. If you do not qualify object with schema , then the database assumes the object is in your own schema. The object can be one of the following types:
Table, view, or materialized view
Procedure, function, or package
Synonym for any of the preceding items
Directory, library, operator, or indextype
Java source, class, or resource
You cannot grant privileges directly to a single partition of a partitioned table.
DIRECTORY directory_name Specify a directory schema object on which privileges are to be granted. You cannot qualify directory_name with a schema name.
JAVA SOURCE | RESOURCE The JAVA clause lets you specify a Java source or resource schema object on which privileges are to be granted.
Listings of System and Object Privileges
When you grant a privilege on ANY object, such as CREATE ANY CLUSTER , the result is determined by the value of the O7_DICTIONARY_ACCESSIBILITY initialization parameter. By default, this parameter is set to FALSE , so that ANY privileges give the grantee access to that type of object in all schemas except the SYS schema. If you set O7_DICTIONARY_ACCESSIBILITY to TRUE , then the ANY privileges also give the grantee access, in the SYS schema, to all objects except Oracle Scheduler objects. For security reasons, Oracle recommends that you use this setting only with great caution.
