Is it possible and feasible to design your own activation system into an indicator or EA?

Quote:

"When selling products on the MetaQuotes Marketplace, the platform allows you to specify a certain number of activations for your product. These activations are tied to a unique installation code that ensures the product only works on the buyer's PC³.

Regarding coding these activations into the indicator's `OnInit` function, the `OnInit` event is used to initialize an MQL5 program, and it's not typically used for handling licensing or activation logic². The activation system is managed by the MetaQuotes Marketplace infrastructure to protect both the seller's intellectual property and the buyer's rights³.

However, if you're looking to implement your own activation system within your code, you would need to design a mechanism that checks for a valid license or activation key when the `OnInit` function is called. This could involve communicating with a remote server to validate the key or using some form of encrypted data within the code to ensure that the indicator is being used in accordance with the license terms you've set."

Of course it is.  But you won’t be able to sell it here at the marketplace
