Impulse MACD is a modified MACD, formed by filtering out the values in a MA range (region between MAs of high and low), thereby reducing whipsaw typical in a sideways market. This is usually plotted as histogram. This also plots the traditional histogram (MACD - Signal), to help in finding entries/exits.
Use this like a traditional MACD (Zero line crossing or Signal crossing).
