Here is a condensed transcript of my latest trading therapy intervention technique: Deco to Client: "I have designed a new trading screen for you. On top is a new measure I call Prolume. Don't worry about how I constructed it. You buy when Prolume is low, and sell when Prolume is high." Client: "....OK, I get it, but what's that on the chart below Prolume?" Deco: "That's a new measure I call Vice." Client: "And what do I do with that?" Deco: "Vice is both fun and bad, right? So you get in when competition for Vice is low, and get out when everybody wants it and Vice is high." Client: "What could be easier?!"
