First of all, introduce what gambling is and what STP is. Betting (MM/DD) refers to the customer's trading order, and the platform vendor bets with the customer himself. When customers make money, they earn the platform, and when they lose money, they naturally lose to the platform. STP is a channel. All orders placed by customers are circulated to banks or exchanges. Whether customers lose money or make money has nothing to do with the platform.
So is the gambling platform legal?
