MACD hay Trung bình động hội tụ phân kỳ bời Gerald Appel, đó là một trong những chỉ số thông dụng nhất. Đó là chỉ số rất an toàn, đơn giản. Cũng là chỉ số mà một nhà phân tích kỹ thuật thích giới thiệu trước tiên | A GUIDE TO TECHNICAL ANALYSIS - MACD The MACD or The Moving Average Convergence Divergence was by Gerald Appel It is one of the most popular indicators. It is a very simple reliable Indicator. Also it is an Indicator a TA enthusiast gets introduced to first. The MACD is constructed by subtracting the longer moving average from the shorter moving average. The resulting plot forms a line that oscillates above and below zero without any upper or lower limits. The MACD is considered to be a momentum oscillator though it is widely used by Trend followers. The most popular formula for the MACD is the difference between the 26-day and 12day exponential moving averages. I will use this standard setting and later if time permits I will try to present other combinations. A 9-day EMA of the MACD line is used as the Chart -1 A positive MACD indicates that the shorter EMA is greater than the longer EMA indicating that momentum is positive. A rising MACD indicates the difference between the short EMA and the long EMA is increasing and in other words indicates a rising momentum. In the same way a negative MACD indicates that momentum is negative and a falling MACD indicates an increasing negative Momentum. KARTHIK MARAR A GUIDE TO TECHNICAL ANALYSIS - MACD Three common signals 1. MA cross over or signal line crossover. The basic and the most common is the signal line cross over. Buy when the MACD line crosses above the signal line and Sell when the MACD line crosses below the signals line. 2. Zero Line crossover. Some use only the zero line cross over as signals. Buy when the MACD line crosses the zero line and Sell when the MACD line crosses below the zero line. 3. Divergences Let us see in a little detail what happens when the moving average cross over and zero line cross over occurs. Let us assume that the stock is in a downtrend and the MACD is below the zero line and below the signal line. Then when the Bullish moving average cross over MACD crossing the signal occurs the .
