Avarice (from Latin avarus, "greedy"; "to crave") Greed and Fear. Fear and Greed. Will one arm ever overpower the other? There most definitely is an art to trading, and it lies somewhere between these two emotions. Trading is an ode to true capitalism. And, to many, an ode to self-destruction. The traditional welcome to this world is telling: You're handed a roll of toilet paper and told, "This place is not for weak stomachs."
