My recently re-written (at the beginning of 2011) software program: SelfAdapINDXWeeklyCndrs, evolved during the last 6 years of trading weekly options. The evolution simplified the software user interface. The NEW Weekly Condor Trading Software focuses on selecting the best 2SigMaxMin Condors from SPX, OEX, and SPY, that is, the one with the greatest potential weekly profit. In a few short minutes the software allows the trader to choose the best Condor to trade for the greatest weekly profit I trade using software I have written using Microsoft's Excel. Recently a reader has used my software on a Macintosh computer. Everything seems to work the same except when copying the CBOE Quotes, an extra blank row appears above the data. One way to solve this problem for Mac computer owners is to add ONE to the formulas (in the formula bar at the top of the screen) in the cells referring to the NOW columns in the Condor sheets for the Call spread rows and then for the Put spread rows. Example = D57 - D58 would have to be changed to D58- D59. The wild market swings (such as caused the May 2010 Flash Crash) have compelled the SEC to introduce required procedures to reduce these wild swings. The 2SigMaxMin Condors help the trader to make weekly profits in spite of what volatility remains after the new SEC procedures Each trading week the trader should select on Friday the best weekly options Condor to open the next Monday which will expire the following Friday expiration. The book explains what the trader must do if the short Call or short Put becomes ITM (In The Money). The trader should follow these procedures to minimize short term losses and make their trading profitable. I modified my software during my 25 years of trading as the market changed. I started using credit index OEX 100 monthly options spreads which required leaving the options spreads open from the third Friday to the third Friday of each month. When Weekly options became available, I found that was a safer way to trade than monthly options since your options positions were only available to be battered by the volatile market for a week at a time: All of the big traders watch the same financial information on Internet: When they see Good Info they buy, causing the market to jump, often more than 2 sigma. When they see Bad News they all sell, causing the market to plunge, often more than 2 sigma. One of the main goals of this book is to show ways I have discovered to avoid weekly options losses when these big Jumps and Drops occur. It is easy to make good profits when the market behaves rationally. It is easy to lose when the market acts irrationally. The object is to generate an income from your options trading account that can be extracted and returned to your bank account to be used as extra income. Or you can leave the profits in your trading account and use the extra capital to trade a larger number of condors to make larger amounts of weekly profit. My new software program is named: SelfAdapINDXWeeklyCndrs which uses 3 Underlying Indices with Weekly Options. I intend to show you how to trade 2 sigma Weekly Condors to obtain Initial Credits of greater than 20% return on your trading capital weekly, yet avoid losses when the big 2 sigma changes occur.
