Michael Marcus, a student of Ed Seykota and one of the most successful traders of all time, once turned a small account into more than $80 million.

He also said something that still holds true today:

“I really feel that if you can trade one market, you can trade them all. The principles are the same. Trading is emotion. It is mass psychology, greed, and fear. It is all the same in every situation.”

Do you agree?
