The OBV-MACD indicator uses the OBV to calculate the cumulative volume, which is then smoothed using two moving averages - fast and slow. The difference between these moving averages is plotted as a histogram, with a signal line plotted over it. A buy signal is generated when the histogram crosses above the signal line, indicating a bullish trend, while a sell signal is generated when the histogram crosses below the signal line, indicating a bearish trend.
This Pine script also includes an OBV-MACD-Donchian version that incorporates Donchian channels for the OBV-MACD. The Donchian channel is a technical analysis indicator that helps traders identify the highs and lows of an asset's price over a certain period. The OBV-MACD-Donchian version uses the OBV-MACD indicator along with the Donchian channels to provide signals that the momentum of OBV is making new high/low during that period of time.
Traders can customize the input parameters of the OBV-MACD indicator, such as the timeframe, method of calculation for the moving averages, and the lengths of the moving averages and breakout lengths. The colors of the plot can also be customized to suit the trader's preferences.
