Hi
The gravity center from Mustafa Belkhayate on Prorealtime is looking close to the following code , anybody has an idea about converting it in Amibroker ??
====================================================
k=p3 // Variable p3= 65
de48=DPO[k*2](close)
if de48=de48[1] and de48[1]=de48[2] and de48[2]<>de48[3] then
flag=1
endif
n=(k*2)-4
p=(n/2)-1
d100=DPO[n](close)
moy100=close-d100
co=(moy100-moy100[1]+(close[p])/n)*n
if flag[1]=1 and flag[2]=0 then
hh=co[1]
endif
if flag[1]=1 then
co=hh
endif
n=p3 mod 2
p=(p3-n)/2
p3=(2*p)+1
once x=0
w=abs((p-x)/p)
w=w*w*w
w=(1-w)
w=w*w*w
x=x+1
if barindex=p3 then
a=0
b=0
e=0
for i=1 to p3
z=barindex-i+1
a=a+w[z]
b=b+w[z]*(i)
e=e+(i)*(i)*w[z]
next
endif
if barindex>p3 then
c=0
d=0
for i=1 to p3
z=barindex-i+1
c=c+co[p3+p-i]*w[z]
d=d+co[p3+p-i]*w[z]*(i)
next
endif
alpha=(a*d-b*c)/(a*e-b*b)
beta=(c*e-b*d)/(a*e-b*b)
lowess=alpha*(p+1)+beta
if barindex < p3*2 then
lowess=undefined
endif
zz = close - lowess
zzsigma = STD[p3](zz)
bb1 = lowess + zzsigma
bb2 = lowess +1.618* zzsigma
bb3 = lowess +2* zzsigma
bl1 = lowess - zzsigma
bl2 = lowess - 1.618* zzsigma
bl3 = lowess - 2* zzsigma
return lowess, bb1, bb2, bb3, bl1, bl2, bl3![]()
