59"Observation, experience, memory and mathematics - A man can have great mathematical ability and unusual power of accurate Observation and yet fail in speculation unless he also possesses the experience and memory"
-- Reminiscences of a Stock Operator
It tells the story of the legendary Jesse Livermore who started his career when he was a teenager working in one of the bucket shops that were common during this time. He had a head for numbers and noticed how stocks reacted during times of heavy buying or selling.
He became smart to the fact that he was able to trade successfuly on what he had learnt.
Excerpt 1
And then, too, if my order was fairly big my own sale would tend further to depress the price. In the bucket shop I didn’t have to figure on the effect of my own trading. I lost in New York because the game was altogether different. It was not that I now was playing it legitimately that made me lose, but that I was playing it ignorantly. I have been told that I am a good reader of the tape. But reading the tape like an expert did not save me. I might have made out a great deal better if I had been on the floor myself, a room trader. In a particular crowd perhaps I might have adapted my system to the conditions immediately before me. But, of course, if I had got to operating on such a scale as I do now, for instance, the system would have equally failed me, on account of the effect of my own trading on prices.
In short, I did not know the game of stock speculation. I knew a part of it, a rather important part, which has been very valuable to me at all times. But if with all I had I still lost, what chance does the green outsider have of winning, or, rather, of cashing in?
It didn’t take me long to realise that there was something wrong with my play, but I couldn’t spot the exact trouble. There were times when my system worked beautifully, and then, all of a sudden, nothing but one swat after another. I was only twenty-two, remember; not that I was so stuck on myself that I didn’t want to know just where I was at fault, but that at that age nobody knows much of anything.
The people in the office were very nice to me. I couldn’t plunge as I wanted to because of their margin requirements, but old A. R. Fullerton and the rest of the firm were so kind to me that after six months of active trading I not only lost all I had brought and all that I had made there but I even owed the firm a few hundreds. There I was, a mere kid, who had never before been away from home, flat broke; but I knew there wasn’t anything wrong with me; only with my play. I don’t know whether I make myself plain, but I never lose my temper over the stock market. I never argue with the tape. Getting sore at the market doesn’t get you anywhere.
Excerpt 2
My brokers bought; not at the level that had made me turn, but at the prices prevailing in the Stock Exchange when their floor man got my orders. They paid an average of fifteen points more than I had figured on. A loss of thirty-five points in one day was more than anybody could stand. The ticker beat me by lagging so far behind the market. I was accustomed to regarding the tape as the best little friend I had because I bet according to what it told me. But this time the tape double-crossed me. The divergence between the printed and the actual prices undid me. It was the sublimation of my previous unsuccess, the selfsame thing that had beaten me before. It seems so obvious now that tape reading is not enough, irrespective of the brokers’ execution, that I wonder why I didn’t then see both my trouble and the remedy for it.
I did worse than not see it; I kept on trading, in and out, regardless of the execution.
