Moving average convergence/divergence (MACD) created by Gerald Appel is probably one of the more popular momentum oscillators in use today. It is calculated using two exponential moving averages (EMAs) of different lengths and is the value of the shorter (fast) period MACD less the value of the longer (slow) period EMA. MACD fluctuates above and below the zero value where the moving averages cross.
In Giorgos Siligardos’ article “Reverse Engineering RSI,” he showed that the reverse-engineered relative strength index (RSI) can help determine the following time period’s closing price using the value of the oscillator. And in the article “RSI Bands,” François Bertrand showed overlaying RSI overbought/oversold levels on the price chart.
I will show the calculation of the price value of a specific MACD level and the calculation of the price value that will cause the MACD to change direction. These values in relation to price can then be shown by overlaying them on the price chart.
