Ignore the other one (it contains some errors).

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

price = input(hl2)
len = input(defval=16,minval=1)
FC = input(defval=1,minval=1)
SC = input(defval=198,minval=1)
len1 = len/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)```

can you please explain how to use it for trading ?

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.
