Myst - I have one simple question....how do you know your system works? There are thousands of systems out there that claim to be the "Holy Grail". Now to your credit, I am not saying that you are implying that is is a "Holy Grail", but then again you are suggesting that this is some remarkable system.
The many examples you site, including QLGC with a 120% return are optimized. There would be no way to know those optimized setting before hand. Now, I have been playing around with your spreadsheet with a large number of stocks. As you have suggested, I went to PCQuote and ran a list of stocks of high volume stocks from the Range Riders. I then went to Yahoo and got historical pricing from 05/18/01 - 11/27/01 and optimized the deviation settings. Then I went back to Yahoo to get historical data from 11/28/01 - 05/31/02 and plugged into the spreadsheet using the optimized data from the earlier period. The results were OK but nothing special.
It is not my intention to attack you. If I am doing something wrong, let me know. I just don't understand what all the hype is all about.
