The Law of Vibration

The Law of Vibration

Ordered behaviour in financial markets and in economic activity is underwritten by a specific behavioural pattern. This pattern - which seems to have known about in antiquity - reflects a learning process, activated by information shocks. It is deeply connected to the dynamics of change and evolution. The pattern was used with extraordinary success by the financial market trader William D. Gann, who then hid it in his best known book. The pattern is now made available for others to research and use.

Forecasting Financial Markets

Forecasting Financial Markets

A seminal work that explains the influence of collective psychology on economic activity and financial market  behaviour. Uncertainty about the outcome of decisions encourages the formation of supportive psychological groupings and the homogenisation of beliefs about the future. The resulting order expresses itself in trends, patterns and rhythms in economic activity and in asset prices. These phenomena, which are often disregraded by economists, have long been accepted by technical analysts.
