Interview with Dr. Alexander Elder at MQL5.com: "I want to be a psychiatrist in the market"

I think financial markets are like manic-depressive patients. Sell when they have mania, and buy when they have depression. The envelope helps me determine where these levels of depression and mania are. There is a joke: "A neurotic is a man who builds castles in the skies, psychotic is the one who lives in them, and a psychiatrist is a person who collects the rent." I want to be a psychiatrist in the market. I want to collect the rent from the madness of the crowd.
