== General Description of the Protection Mechanism ==
When protecting the study the source code is exported to an assembly (DLL), which is protected by any NET obfuscator. MC .NET Special Edition features the Confuser Ex obfuscator. User can also use any other obfuscator. When importing the protected study a class inherited from the encrypted assembly is created. The encrypted assembly is connected via references.
In case the Study is used on several computers at the same time, the last user disconnects all connected users in 5 minutes.

=== Step 1: Register with MultiCharts LLC as a Developer ===
=== Step 2: Select a Name for the Study ===
=== Step 3: Add a DRM Call Code to Your Study == ===In MultiCharts (PowerLanguage)=== Add the [[VerifyLicense]] function to your study. For example: <syntaxhighlight>VerifyLicense("Moving Average", "Adam.Smith@gmail.com");</syntaxhighlight> ===In MultiCharts .NET===
=== Step 4: Create Export a Protected Study == ===In MultiCharts (PowerLanguage)=== After the study is connected to DRM, it should be exported to a SEF (read-only) file: [[Importing_and_Exporting_Studies#Exporting_Studies_in_SEF_.28Read-only.29_Format|'''see how''']]. SEF study can be distributed to the users. ===In MultiCharts .NET=== After the study is connected to DRM, it should be exported to a PLN file with protection. <br>To do this the following should be done in PowerLanguage Editor: 1. In the main menu click '''File''' and select '''Export...''' <br> [[File:SE_DRM 4.png]] <br> 2. Select the study to export. <br>3. Enable the '''Protect''' option. <br>4. Select a protection tool (the drop-down list is visible only if the '''Protect''' option is enabled). <br>5. Click '''OK'''. <br>[[File:SE_DRM 5.png]]<br> Exported study can be distributed to the users. <div style="background-color: #E3FBE5;">'''Note:'''# Study can be used without registration only if a trial period other than 0 is indicated when creating the study. When the trial period ends the study will ask for the key necessary to continue working with the study.# You can protect the assembly using the built-in obfuscation tool or configure the application to use any other tool. The following obfuscators do not need additional configuration in PowerLanguage Editor: NET Reactor, Agile DOT NET, dotfuscator and Cli Secure.</div> <br> == Step 5: Managing Licenses == Go to the Licenses section to create a key. [[File:SE_DRM 6.png]] Initially the table is empty. To allow the user to use your study you should create a license. <br>To do this, click the '''New item''' button. [[File:SE_DRM 7.png]] The following information should be indicated for the new license: * User name, which will be used to display the user who has purchased the study (not required);* Select a study from the drop-down list;* The key will be generated automatically;* Date will be determined automatically: Default License Period will be added to the current date. The date also can be set manually. [[File:SE_DRM 8.png]]
