# Fractal Adaptive Moving Average (real one)

Ignore the other one (it contains some errors).

On this FRAMA you can play with length, SC             and FC             .

```//@version=2
price = input(hl2)
len = input(defval=16,minval=1)
FC = input(defval=1,minval=1)
SC = input(defval=198,minval=1)
len1 = len/2
w = log(2/(SC+1))
H1 = highest(high,len1)
L1 = lowest(low,len1)
N1 = (H1-L1)/len1
H2 = highest(high,len)[len1]
L2 = lowest(low,len)[len1]
N2 = (H2-L2)/len1
H3 = highest(high,len)
L3 = lowest(low,len)
N3 = (H3-L3)/len
dimen1 = (log(N1+N2)-log(N3))/log(2)
dimen = iff(N1>0 and N2>0 and N3>0,dimen1,nz(dimen1[1]))
alpha1 = exp(w*(dimen-1))
oldalpha = alpha1>1?1:(alpha1<0.01?0.01:alpha1)
oldN = (2-oldalpha)/oldalpha
N = (((SC-FC)*(oldN-1))/(SC-1))+FC
alpha_ = 2/(N+1)
alpha = alpha_<2/(SC+1)?2/(SC+1):(alpha_>1?1:alpha_)
out = (1-alpha)*nz(out[1]) + alpha*price
plot(out,title="FRAMA",color=blue,transp=0)```

Thanks for update on FRAMA.
I think still 1 error on line 18, is aduot Fractal Dimension ane I check for formula.

D = (Log(HL1 + HL2) – Log(HL)) / Log(2)

XXXX Note: Log(2) = Log(N / (½N)) XXXXX ___ Look at Log(2) _____

HL1 = (Max(High,½N..N) – Min(Low,½N..N)) / ½N

HL2 = (Max(High,½N) – Min(Low,½N)) / ½N

HL = (Max(High,N) – Min(Low,N)) / N

N = Periods

If D < 1 then D = 1

If D > 2 then D = 2

Has the @Shizaru indicator been updated with this correction?

Ok MarcoValente told me that in the they found out that there is no need for this change, it's exactly the same.
janfry
...therefore the indicator works as it is.
