MACD Histogram with Colors (v2)

Description

This MACD Histogram with Colors indicator allows you to set colors for both positive and negative values of the Histogram.

Based on the original MACD Histogram indicator from cTrade.

v2

+ Adaptive (auto-color): Allows the option to display adaptive auto-colors changing according the trend.

+ Verbose: Allows the option to display the current Long or Short cycle and it's value.

v1

Great coding, but how about keeping the entry and exit positions simple

i.e.  

public override void Calculate(int index)
        {
            if(MacdHistogram.Histogram.IsFalling()) 
            {
                HistogramNegative[index] = MacdHistogram.Histogram[index];
            }
            
            if (MacdHistogram.Histogram.IsRising())
            {
                HistogramPositive[index] = MacdHistogram.Histogram[index];
            }

// comment : instead of
            //if (MacdHistogram.Histogram[index] > 0)
            //{
            //    HistogramPositive[index] = MacdHistogram.Histogram[index];
            //}

            //if (MacdHistogram.Histogram[index] < 0)
            //{
            //    HistogramNegative[index] = MacdHistogram.Histogram[index];
            //}

            Signal[index] = MacdHistogram.Signal[index];
        }

then use the if (%K > %D)  while macdhistogam isRising() {position.long} else if ( %D>%K)  while macdhistogam isFalling() {position.short}
