In his new book, Dimitris Dimopoulos presents the medium-term trading system of Technical Analysis of the pivot, similar to Richard Donchian's weekly rule, particularly suitable for trading and investing in the Athens Stock Exchange. The advantages of the pivot system: (a) It is a very simple mechanical system that follows the trend and signals purchases when the General Index, after a recession, recovers and breaks above the 20-day High. It signals sales when the General Index, after an upward trend, declines and breaks below the 20-day Low. (b) It is complemented by similar alternative pivot systems that provide signals for gradual market entries/exits, as well as for investors who do not want to trade their entire capital in a single move. (c) It has been successfully tested on the historical data of the General Index over the last two decades. (d) The individual buy/sell signals of the pivot are subject to evaluation based on confirmatory factors such as trading volumes, the direction of the main trend, and the charting status of various other indicators. In this way, the trader determines the degree of entry into the respective signals of the pivot systems. Additionally, the book presents: - Trading systems that successfully operate against the trend in overbought and oversold price zones - Short to medium-term candlestick method systems - Exceptional short-term high-accuracy systems for fast traders
