Dr. Elder’s Impulse Indicator (System)

The impulse system, a system designed by Dr. Alexander Elder for identifying appropriate entry points for trading on momentum, uses one indicator to measure market inertia and another to measure market momentum. To identify market inertia, you can use an exponential moving average (EMA) for finding uptrends and downtrends. When EMA rises, the inertia favors the bulls, and when EMA falls, inertia favors the bears. To measure market momentum, the trader uses the moving-average-convergence-divergence (MACD) histogram, which is an oscillator displaying a slope reflecting the changes of power among bulls and bears. When the slope of the MACD histogram rises, bulls are becoming stronger. When it falls, the bears are gaining strength.  Source: Investopedia
