"Laws change more slowly than custom, and though dangerous when they fall behind the times are more dangerous still when they presume to anticipate custom."

In a narrow market, when prices are not getting anywhere to speak of but move within a narrow range, there is no sense in trying to anticipate what the next big movement is going to be. The thing to do is to watch the market, read the tape to determine the limits of the get nowhere prices, and make up your mind that you will not take an interest until the prices breaks through the limit in either direction.
