Περιγραφή This book is not a book in theoretical econometrics, neither a classical book of technical analysis. The main purpose of it is to support conceptually and technically, designers of algorithmic trading, so as to find, code and conduct algorithmic trading in the capital markets and foreign exchange currencies (Forex). It tries to fill the gap between strictly practical recipes of technical analysis and economic-statistical scientific principles and concepts that may lead to the discovery of stable and reliable trading methods that may go on successfully for many decades. The source of these concepts are twofold: 1) From the rhythms of the natural ecological environment 2) From the social economic structure. 3) Almost all of the concepts derive from scientific discoveries that are not within the scope of this book. The book concludes successfully with 4 coded algorithms of trading capable of consistent capitalization at least for the last 10 or more years.Extensive coding (more than 150,000 lines of code) simulation, and live trading, was required for the last 10 years, by the author so as to acquire the expertise, to write this book. A great part of the research was sponsored by the program of innovation and entrepreneurship of the Institute of Education and Technology (T.E.I.) of Epirus in Greece.
