Felipe Tudela is president of the centre de Recherche Financiere and manages a limited partnership for a group of private investors. He has lectured in France and abroad for various financial institutions such as the Bank of France, the London Society of Technical Analysts, the FOW group and the French Association of Technical Analysis. He is a member of the board of AFATE(French Association of Technical Analysis) and creator of the triads, a market model that enables the user to analyse market behaviour without many of the inconveniences of normal distribution based indicators, thus avoiding many of their false signals. He is the author of Methode Triades, a book that explains this model, and which is used by leading financial institutions. His most recent discovery, and the subject of this book, is the original way to trade Japanese candlesticks and their use in conjunction with Sokyu Honma's five Sakata methods. He currently trades the markets, writes, lectures and does research on technical analysis.
