****Aroon Histogram (I set it to 150 or 200)****
Code Below. 





plot Data = close;#Tommy Staab

declare lower;

input length2 = 100;

def up_index2 = GetMaxValueOffset(data = high, length = length2);

def down_index2 = GetMinValueOffset(data = low, length = length2);

def Up2 = (length2 - up_index2) * 100.0 / length2;
def Down2 = (length2 - down_index2) * 100.0 / length2;

def alert = (close);
def alert2 = (close);


plot signal = if up2 < down2 then alert else double.nan;
plot signal2 = if up2 > down2 then alert2 else double.nan;


signal.setdefaultcolor(color.red);
signal.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);
signal2.setdefaultcolor(color.green);
signal2.SetPaintingStrategy(PaintingStrategy.HISTOGRAM);








****Multiple Time Frame MACD with 3 filtering periods.****
I use default settings.  
Code below.
