I reviewed Ganntrader in STOCKS & COMMODITIES in February 1987. For the review I interviewed users
of the program, and I found they had high praise for it. They also wore out many of the normally rugged
Epson printers doing their Gann studies.
Ganntrader 2 changes that. Besides plotting long and large charts on dot matrix printers, it also plots
them to the screen in crisp, dazzling colors, greatly increasing the efficiency of trying various scale
factors, Gann angles, Gann squares, and so forth. Where one chart previously took 20 minutes to print, it
now takes seconds to display on the screen.
Ganntrader 2 is an easy-to-use program with pop-down menus. Installation was trivial, and the
Ganntrader program itself worked flawlessly. I did have some initial problems with the GrafPlus screen
dump program included, but after some trial and error got it to dump the screens to files the way I wanted
(Figures 1 through 3).
