I have been trading Weekly Index Options since they become available on the Chicago Board of Options Exchanges in 2003. I have watched this type of Options Trading mature as the Traders became more sophisticated and the trading software I have developed became more refined and easy to use. The Principle Strategy I use for trading Index Options is to use Condors: Short Calls 2 Standard Deviations (sigma) above the market and the Long Calls the next strike price higher; Short Puts 2 standard Deviations below the market and the Long Puts the next strike price lower. I have developed software using Index Options and Growth Stocks. I have simplified the software so that it uses only the following Index Options with Weekly Options expiring each Friday: SPX (S&P 500) OEX .(S&P 100), which is about 1/2th the SPX SPY (SPDR S&P 500 ETF Trust), sometimes called the Mini-SPX, since it is about 1/10th SPX Jon Schiller received the BS in Physics from the California Institute of Technology (Caltech) and the MS and Ph.D. from the University of Southern California (USC).
