WD Gann’s Wheat Trade 1909
“One of the most astonishing calculations made by Mr. Gann was during last summer  when he predicted that September Wheat would sell at $1.20. This meant that it must touch that figure before 28 the end of the month of September. At twelve o’clock, Chicago time, on September 30th (the last day) the option was selling below $1.08, and it looked as though his prediction would not be fulfilled.
Mr.Gann said, ‘If it does not touch $1.20 by the close of the market it will prove that there is something wrong with my whole method of calculation. I do not care what the price is now, it must go there.’
It is common history that September Wheat surprised the whole country by selling at $1.20 and no higher in the very last hour of trading, closing at that figure.”
