"I noticed that in advances as well as declines... prices were apt to show certain habits, so to speak. There was no end of parallel cases and these made precedents to
guide me. I was only fourteen, but after I had taken hundreds of observations in my mind I found myself testing their accuracy, comparing the behaviour of stocks to-day
with other days. It was not long before I was anticipating movements in prices. My only guide, as I say, was their past performances. I carried the "dope sheets" in my mind. I
looked for... prices to run on form. I had "clocked" them. You know what I mean... Another lesson I learned early is that there is nothing new in Wall Street. There can't be
because speculation is as old as the hills. Whatever happens in the... market to-day has happened before and will happen again."
