    For future reference, the pinescript instruction “correlation” is the same as this prorealtime code:

    ProBuilder" >//correlation(x, y, len)

len = 20
x = barindex
y = customclose

lenMinusOne = len - 1
meanx = 0.0
meany = 0.0
for i=0 to lenMinusOne
meanx = meanx + (x[i])
meany = meany + (y[i])
next
meanx = meanx / len
meany = meany / len
sumxy=0.0
sumx=0.0
sumy=0.0
for i=0  to lenMinusOne
sumxy = sumxy +    ((x[i]) - meanx) * ((y[i]) - meany)
sumx  = sumx  + pow((x[i]) - meanx, 2)
sumy  = sumy  + pow((y[i]) - meany, 2)
correlation = sumxy / sqrt(sumy * sumx)
next

return correlation
