Hi,

I have an indicator here to measure the linear regression as follow:

//Parameters :
Len = 100
percent = 0.002

once j=0
de48=DPO[Len*2](close)
if de48=de48[1] and de48[1]=de48[2] and de48[2]<>de48[3] then
flag=1
endif

n=(Len*2)-4
p=(n/2)-1
d100=DPO[n](close)
moy100=close-d100
co=(moy100-moy100[1]+(close[p])/n)*n
if flag=1 and flag[1]=0 then
test=linearregression[Len](co)
test1=linearregressionslope[Len](co)
a=test1
b=test-test1*Len
endif

if flag=0 then
reg=undefined
upperchan=undefined
lowerchan=undefined
else
j=j+1
reg=a*j+b
upperchan = reg + reg*percent
lowerchan = reg – reg*percent
endif

RETURN reg COLOURED(0,0,255) as “channel center”, upperchan COLOURED(0,255,0) as “upper channel”, lowerchan COLOURED(255,0,0) as “lower channel”

It looks like in the the attached picture.

I create a scnner to scan which stock has the positive LR as follow but it finds nothing:

//Parameters :
Len = 100
percent = 0.002

once j=0
de48=DPO[Len*2](close)
if de48=de48[1] and de48[1]=de48[2] and de48[2]<>de48[3] then
flag=1
endif

n=(Len*2)-4
p=(n/2)-1
d100=DPO[n](close)
moy100=close-d100
co=(moy100-moy100[1]+(close[p])/n)*n
if flag=1 and flag[1]=0 then
test=linearregression[Len](co)
test1=linearregressionslope[Len](co)
a=test1
b=test-test1*Len
endif

if flag=0 then
reg=undefined
upperchan=undefined
lowerchan=undefined
else
j=j+1
reg=a*j+b
upperchan = reg + reg*percent
lowerchan = reg – reg*percent
endif

c1 = reg > 1

SCREENER[c1]

What could be the problem?
