MONTY LEE  By far the most comprehensive and complete stock analysis package for the Macintosh. Investor/RT lets you track prices (via several sources, both online and terminal) and then perform complex analysis (Bollinger Bands, moving averages, candlestick, and dozens more). I/RT comes with its own language for you to write scans, back-testing analysis, and more. For anyone that needs more than the simple tools provided online, I/RT will meet any need

It runs great in OS X. My only critique is that the program has grown so powerful that the documentation lags several generations behind the program, and figuring out all the power takes a lot of time. The program also does not follow some Macintosh standards, and so common keyboard actions don't work like expected. Because of the developer's tools, it is not as Mac friendly as you'd expect. But it is stable (doesn't crash), very fast (takes advantage of dual processor Macs), and easy to initially set-up and run.

I recommend this program to any serious investor wishing to study price and volume of any commodity (stocks, bonds, options, etc.). There is no program as complete, and certainly none as powerful as Investor/RT.  (Version 7.2 rev 1)
