Mark Wolfinger has been a professional options trader since 1977. After 23 years as a market maker on the trading floor at the Chicago Board Options Exchange (CBOE), in 2000 he turned his attention to educating new option traders. He published three dead-tree books and seven eBooks, all based on the concept of teaching people that options are nothing to fear, but instead are risk-reducing investment tools.
