OBV with an extra twist.
Add up to 4 moving averages and choose from simple, exponential, smoothed, etc.
Choose to display a trend fill. Fill will be green when above the MA4 or red when below it. If the difference between the MA1 and MA4 is growing, the trend fill will be a more solid color indicating a strengthening trend. If the gap is lessening, it will gradually get more transparent indicating a weakening trend.
Finally, options to display bullish and bearish regular and hidden divergences are included.
