Hello All, 

Is there a simple way to licence a cBot, so i.e. the bot would run only on buyers account or buyers machine?

Thank you 

Patrick

 

Yes, you can read the processor ID and then create a hash code from it. Write it to a text file and then check the contents of that file when your BOT runs...

The problem I've run in to licensing a single account is that people quite often have 2 or 3 demo accounts that they use for testing and then a different account for live trading... it can end up a bit messy !

I've ended up writing a licensing BOT that sends the request through to me and then I email the license code to the user, they copy & paste the code in to the License BOT and re-run it to generate the text file that contains the code. Any other BOTS you write can then check the contents of this file.

Hi Lisa, do you mind to share the source code for your licensing bot? Just need some reference. Many thanks.

Check that License Generator

It binds the cBot to cTrader account using user ID number which is obtained by this indicator

The proposed method for licensing is to use a central and online licensing system known as the "License Server." In this approach, the process of generating, issuing, and managing licenses is done automatically and online, eliminating the need for accessing user information or interaction between the licensor and the user.

Here's how it works:

1. License Server: Set up a License Server that handles the generation, issuance, and management of licenses. The server utilizes a dedicated database to store and manage license information.

2. License Code Generation: Upon purchasing the robot, a unique license code is provided to the user by the License Server.

3. License Issuance: The user enters the license code into the robot after the purchase, and the robot sends this code to the License Server.

4. License Validation: The License Server checks and validates the license code. If it's valid, the server grants permission to the robot to continue functioning within the valid time frame.

5. Online Updates: Whenever there is a need for updates or license extensions, the user can interact with the License Server to perform the necessary actions.

Advantages of using the License Server approach:

- High Security: User information is protected, and only valid license codes are sent to the robots.
- Easy Management: Licenses are automatically managed, eliminating the need for manual interventions or contacting users.
- Flexibility: The central system allows for customized license types and durations based on specific user needs.
- Easy Updates: Updates can be performed online, providing users with a seamless process for continuous updates.

It's important to note that while the License Server approach enhances security, proper security measures need to be implemented on the License Server itself to prevent any unauthorized access and protect user data.
