Public Function MACDHistogram(longCycle As Integer, ShortCycle As Integer, SignalPeriod As Integer) As String
The MACD is a moving average oscillator that shows potential overbought/oversold phases of market fluctuation.
The MACD is a calculation of two moving averages of the underlying price/indicator. The histogram is simply a bar graph of the MACD minus the MACD Signal line.
Buy/Sell interpretations may be derived from crossovers (calculated from the Signal Periods parameter), overbought/oversold levels of the MACD and divergences between MACD and actual price.
Returns the handles of a technical indicator, in case of failure returns a empty string.
