The semiretired chairman of the board of the brokerage firm was a longtime trader with nearly 40 years of experience in the grain pits at the Chicago Board of Trade. He didn't know much about technical analysis, because he never needed it to make money on the floor. But he no longer traded on the floor and found the transition to trading from a screen difficult and somewhat mysterious. So he asked the firm’s newly acquired star technical analyst to sit with him during the trading day and teach him technical trading. The new hire jumped at the opportunity to show off his abilities to such an experienced and successful trader.

The analyst was using a method called “point and line,” developed by Charlie Drummond. (Among other things, point and line can accurately define support and resistance.) One day, as the two of them were watching the soybean market together, the analyst had projected major support and resistance points and the market happened to be trading between these two points. As the technical analyst was explaining to the chairman the significance of these two points, he stated in very emphatic, almost absolute terms that if the market goes up to resistance, it will stop and reverse; and if the market goes down to support, it will also stop and reverse. Then he explained that if the market went down to the price level he calculated as support, his calculations indicated that would also be the low of the day.

As they sat there, the bean market was slowly trending down to the price the analyst said would be the support, or low, of the day. When it finally got there, the chairman looked over to the analyst and said, “This is where the market is supposed to stop and go higher, right?” The analyst responded, “Absolutely! This is the low of the day.” “That’s bullshit!” the chairman retorted. “Watch this.” He picked up the phone, called one of the clerks handling orders for the soybean pit, and said, “Sell two million beans (bushels) at the market.” Within thirty seconds after he placed the order, the soybean market dropped ten cents a bushel. The chairman turned to look at the horrified expression on the analysts face. Calmly, he asked, “Now, where did you say the market was going to stop? If I can do that, anyone can.”
