Behold! Macintosh version 2.2

by John Sweeney

Software developers have successfully installed trading system logic in most prominent packages for DOS and Windows users. Rarer is the complete package for the Macintosh user. One prominent development environment for the Mac is Behold!. Combining graphics, spreadsheet data manipulation, trading rules and testing results in one program, Behold! makes system development as easy as it's likely to get.

Using Behold! is like starting with a Microsoft Excel worksheet that has miraculously sprouted an automatic graphing capability and a simple means of specifying trading rules. Those of us who've painstakingly contorted Excel into trading models have enjoyed the freedom of data access and the power of the formulary but cursed the manipulations necessary for graphs and the tedious summarizing of testing results. After many iterations, you have a generic testing model into which you slap new data now and then, but there always seems to be another tweak necessary, leading you into spending more time programming than conceptualizing trading.

AN EDUCATIONAL APPROACH

Behold! developer Jim Payne is clearly familiar with trading system development as well as the benefits of the spreadsheet format. However, Payne didn't stop there. Another major plus of Behold! is the instructional approach of the manual.

Reading the manual is not only an exercise in familiarization but also a course of study in system development. What other manual throws in a great quick-and-dirty calculation for figuring the number of trades to reach 95% confidence levels? Or explains why you'd want to cut up data files to test segments individually? Or gets into terminal wealth relatives (the ratio of original capital to final capital for optimal capital traded), as popularized by Ralph Vince?
