The 'AccessRights' Class Property¶
To protect our users from malware code, we run every cBot or indicator in a sandboxed environment.
As a result, cBots and indicators must declare their required access rights via the
AccessRights class property as shown below.
The boundary values for the
AccessRights property are as follows.
None. The extension only has access to the platform-provided API data. It will not be able to access anything outside the platform.
FullAccess. The extension has unlimited access rights. It can access the Internet, read/write files, and run other executables, etc. It can also import WinApi functions, use .NET reflection, and create windows.
Please consult our references library for a full list of the values that the
AccessRights class property can take. As shown below, it is possible to combine access rights when defining new classes.
AccessRights.FullAccess is declared, the following window will be shown when running an instance of the cBot/indicator in question.
If your cBot/indicator attempts to perform a restricted action, the code will throw a security exception.
For example, if a cBot with
AccessRights.None tries to read from a text file, it will be stopped and the following message will appear in the log.
Crashed in OnStart with SecurityException: Request for the permission of type 'System.Security.Permissions.FileIOPermission, mscorlib, Version=18.104.22.168, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
The surest way to avoid this exception is to declare
AccessRights.None for all your extension unless you plan on distributing them to other traders.
When sharing or selling your cBots/indicators, we highly recommend setting the value of the
AccessRights parameter to
