In Gann’s fiction novel “The Tunnel Thru The Air,” it is through the fringe adventures of the young Robert Gordon that Gann walks you through the theory, rules, and applications of his entire trading system- in a bizarre, slapstick veiled language at times. There is more here encoded than in any other of his writings, save “The Truth Of The Stock Tape.” The fictitious story goes like this: Gordon finds a blueprint in the Bible for a unique flying machine. Through the course of its development, he meets and then loses Marie, the love of his life. Gordon’s flying machine ends up saving America in an upcoming world war that Gann predicts will take place.
