Change MACD Divergence to Stochastic..

[EddieM]

I found this Free indicator link from the video below.
It works off MACD.
It auto draws the divergence line on the chart both up top and bottom so two parts

Can someone change this into a Stochastic version with the K and D so it draws the lines on both upper and lower but using the D Stochastic it looks for to create the lines it draws. The MACD misses a lot that the D Stochastic would find.

# Mechanical MACD Divergence (lower chart)
# with both standard & volume-weighted MACD

input fastLength = 12;
input slowLength = 26;

def fastAvg;
def slowAvg;

switch (MACD_Type) {
case "Standard":
    fastAvg = MovingAverage(averageType, close, fastLength);
    slowAvg = MovingAverage(averageType, close, slowLength);
case "Volume Weighted":
    fastAvg = sum(volume * close, fastLength) / sum(volume, fastLength);
    slowAvg = Sum(volume * close, slowLength) / Sum(volume, slowLength);
}

plot Avg = MovingAverage(averageType, Value, MACDLength);
