Just be mindful that anything can happen in the market. This a quote from Chapter 6 of Trading in the Zone by Mark Douglas.
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."
