'In those days, there \\,ere no personal computers b e ~ o ~tlhde
Apple. There were few, if any, tlesible softmare pacliages a\'ailable.
These machines, far from bcing the ubiquitous tool seen
e\~erywhere in the world of finance and the world at large today,
were the province of computer nerds . . . I set out to design a system
for trading commodities. But things changed quiclily and radically
as soon as I started trading. My trading program, ho\\.ever, did not
change at all. i\s I said, it hasn't changed even to this day.'.' John. W. Henry
