Cycle High/Low Stoch

Mr. Pete, I’m glad you are recovering well.

I’m trying to write a script that uses the full stochastic to mark cycle highs and lows. The definition of the high is %D crosses above 45 and then back below 55 and the low is marked by %D crossing below 45 and back above 55. I’m pretty much stuck, all I’m getting are red and green arrows accross the bottom of the chart. Please take a look at the script below, one glance and you can tell I don’t know what I’m doing 🙂 Any help or suggestions would be greatly appreciated.

input over_bought = 80;
input over_sold = 20;
input KPeriod = 10;
input DPeriod = 5;
input priceH = high;
input priceL = low;
input priceC = close;
input slowing_period = 3;
input averageType = AverageType.SIMPLE;

def lowest_k = Lowest(priceL, KPeriod);
def c1 = priceC – lowest_k;
def c2 = Highest(priceH, KPeriod) – lowest_k;
def FastK = if c2 != 0 then c1 / c2 * 100 else 0;

def FullK = MovingAverage(averageType, FastK, slowing_period);
def FullD = MovingAverage(averageType, FullK, DPeriod);

def OverBought = over_bought;
def OverSold = over_sold;

def upK = FullK crosses above OverSold;
def upD = FullD crosses above 55;
def downK = FullK crosses below OverBought;
def downD = FullD crosses below 45;
def cycleLow = if downd then low < low[1] and low < low[-1] else 0;
def cyclehigh = if upd then high > high[1] and high > high[-1] else 0;

plot UpSignal = cycleLow;
plot DownSignal = cyclehigh ;

UpSignal.SetDefaultColor(Color.UPTICK);
UpSignal.SetPaintingStrategy(PaintingStrategy.ARROW_UP);
DownSignal.SetDefaultColor(Color.DOWNTICK);
DownSignal.SetPaintingStrategy(PaintingStrategy.ARROW_DOWN);
