Two Leg Remote is the same Two Leg, only the second leg works on your second computer. Each computer has its own IP address and its own broker account, and the broker sees two accounts on two different devices. The roles of the two computers, the session key, what both tabs show while the strategy works, and what happens when the link drops and on stop.
Locked lessons come with the product. The video, the text and the trainer open on this very page right after payment.
