I am new to the RW Community. It seems to be relatively inactive. Moreover, it is difficult to use. For example, the latest post is not listed at the top of the page, but rather the bottom, forcing one to page down many pages to find it. Also, I have been unsuccessful in downloading .und files posted by other members. It seems that all that I get is a file of html source code for the web page in question rather than the .und file. A new issue of "Tips and Tricks" supposedly is posted every other week, but I have yet to see any new ones posted. Any one have any tips to make this site more user friendly?
Here is some more evidence just how buggy RW backtesting is:
With just 1 stock selected in each period of a screen backtest the following results are obtained:
Stock Price Return
8/31/12 USPI 0.08
9/7/12 USPI 0.08 1.7%
9/14/12 USPI 0.08 1.7%
9/21/12 USPI 0.08 1026.7%
9/29/12 USPI 0.90
So, return is calculated as 1.7% more than it should be in each of the periods shown. Also for the same backtested screen CMNFY is the single stock selected from 4/23/10 through 6/4/10. The price of CMNFY is constant at 300 throughout this period, but for each of these periods the return calculated for the screen in the backtest is shown to be 4.1%, whereas it should be 0%. How can any calculations of RW backtesting be trusted?
