On The Importance Of Knowing Right From Wrong:
“There is at least one thing that all good tape readers knew that still
holds true today. When you make a trading decision, you should feel absolutely
confident that you are right, but you must also recognize that the market can
prove you wrong. In other words, you are absolutely right until proven
wrong.”

Trader Vic — Methods of a Wall Street Master,
(1991, John Wiley & Sons, New York).
