Preface

This book is based upon the belief that the movements of prices on the exchanges are dependent to a very large degree on the mental attitude of the investing and trading public. It is the result of years of study and experience as fellow at Columbia University, news writer, statistician, on the editorial staff of The Magazine of Wall Street, etc.

The book is intended chiefly as a practical help to that considerable part of the community which is interested, directly or indirectly, in the markets; but it is hoped that it may also have some scientific value as a preliminary discrussion in a new field, where opportunities for further research seem almost unlimited.
