Funding of accounts

 
Hello, i have a signal that is avaliable for subscription. And the people who are subscribed have to pay for that every month and aswell a vpn every month. But , do they have to manually top up their account every month or can the mql balance top up automatically from their trading account? Everything should go automatic, if this is not possible, can we set up a monthly withdrawal from thei personal cards/paypal. Thanks
