The tape is like a moving picture film. Every minute of the day it is demonstrating whether supply or demand is the greater. Prices are constantly showing strength or weakness: strength when buyers predominate and weakness when the offerings overpower the buyers. All the various phases from dullness to activity; from strength to weakness; from depression to boom, and from the top of the market down to the bottom – all these are faithfully recorded on the tape. All these movements, small or great, demonstrate the workings of the Law of Supply and Demand.
And now that you are undertaking to learn this Method, it is best that you prepare your mind for it by discarding most of the factors that you have heretofore employed in forming your judgment and making your decisions, such as: tips, rumors, news items, newspaper and magazine articles, analyses, reports, dividend rates, politics and fundamental statistics; and especially the half-baked trading theories which are expounded in boardrooms and popular books on the stock market.
It is not necessary for you to consider any of these factors because the effect of all of them is boiled down for you on the tape. Thus the tape does for you what you are unable to do for yourself; it concentrates all these elements (that other people use as a basis for their stock market actions) into the combined effect of their buying and selling.
You draw from the tape or from your charts the comparatively few facts which you require for your purpose. These facts are: (1) price movement, (2) volume, or the intensity of the trading, (3) the relationships between price movement and volume and (4) the time required for all the movements to run their respective courses.
You are thus far better equipped than the man who is supplied all the financial news, statistics, etc., from the whole world.
