Hi,

My screener code looks as follow:

once l=21
once o=3
once m=3
once fast=12
once slow=26
once smooth=9
once n=300

// Define KDJ
hi = highest[l](high)
lo = lowest[l](low)
oscillator = (close – lo) / (hi – lo + 0.001) * 100
rsv = ExponentialAverage[m](oscillator)
k = ExponentialAverage[m](rsv)
d = ExponentialAverage[o](k)
j = 3*k – 2*d

// Define MACD
DIF = ExponentialAverage[fast](Close) – ExponentialAverage[slow ](close) // MACD
DEA = ExponentialAverage[smooth](DIF) // Signal
MyMACD = (DIF-DEA)//*2 // Histo

// Define MJ
KH=highest[n](K)
DH=highest[n](D)
JH=highest[n](J)
KL=lowest[n](K)
DL=lowest[n](D)
JL=lowest[n](J)
KDJMAX=MAX(KH,MAX(DH,JH))
KDJMIN=MIN(KL,MIN(DL,JL))
KDJM2=(KDJMAX+KDJMIN)/2
KDJA2=(KDJMAX-KDJMIN)

DIFH=highest[n](DIF)
DEAH=highest[n](DEA)
MACDH=highest[n](MYMACD)
DIFL=lowest[n](DIF)
DEAL=lowestBars[n](DEA)
MACDL=lowest[n](MYMACD)
MACDMAX=MAX(DIFH,MAX(DEAH,MACDH))
MACDMIN=MIN(DIFL,MIN(DEAL,MACDL))
MACDM1=(MACDMAX+MACDMIN)/2
MACDA1=(MACDMAX-MACDMIN)

NEWBASE=(0-MACDM1)*KDJA2/MACDA1+KDJM2

NewJ = J-NEWBASE
/////////////////////

// Long

long1 = ((NewJ crosses over 0) or (NewJ[1] crosses over 0))

SCREENER[long1] (close * Volume AS “Markt”)

But as I scan the NYSE the result is zero. It must not the truth. Wenn I take out the last 2 lines and set RETURN NewJ as indicator, it works. There must be something wrong?
