There is no place for arrogance on the trading floor. The stock market has the uncanny ability to identify and humble arrogant traders. The best traders respect the market at all times. Traders are most susceptible to arrogance after an extended winning streak. It’s amazing how weeks of disciplined trading can be wiped out by one bad day. Arrogance is a virus in your trading, as it eats away at the edges of your discipline. Without proper discipline, the market will eat you for lunch.
