Their signals are unreliable, almost seems randomly generated. Take a screenshot of their signals one day, and refer back to it another day. You will see some signals neither show up in active nor in historic signals. I also experienced payment problems with these people and once you give them your card details, unless you cancel your card itself, they will never stop charging your card. You just cant cancel the contract on the platform, and no human contact exists on their support email. Most likely a low life group of scammers.
