FRAMA seems to be the evolution of the current and much-used EMA . The basic strategy is simple: long if the price crosses up the line, short or exit if vice versa.

The main difference between EMA and FRAMA is that the first one seems to lag much more than the first one, as we can see from the chart below ( crude oil daily chart )

FYI

Here is the code from Ami which acts exactly the same with the code from Sierra. Could u give it a try

// FRAMA - Fractal Adaptive Moving Average

Price = (H+L)/2;

N = Param( "N", 16, 2, 40, 2 ); // must be even

N3 = ( HHV( High, N ) - LLV( Low, N ) ) / N;

HH = HHV( High, N / 2 ) ;

LL = LLV( Low, N / 2 );

N1 = ( HH - LL ) / ( N / 2 );

HH = HHV( Ref( High, - N/2 ), N/2 );

LL = LLV( Ref( Low, - N/2 ), N/ 2 );

N2 = ( HH - LL ) / ( N / 2 );

Dimen = IIf( N1 > 0 AND N2 > 0 AND N3 > 0, ( log( N1+N2) - log( N3 ) )/log( 2 ), Null );

alpha = exp( -4.6 * (Dimen -1 ) );

alpha = Min( Max( alpha, 0.01 ), 1 ); // bound to 0.01...1 range

Frama = AMA( Price, alpha );

Plot( Frama, "FRAMA("+N+")", ColorRGB(255,0,0), styleThick,maskAll );

Here the correct code, just copypaste on a new indicator if you want to use it (default settings are FC =1, SC =198, length =16, same as Ehlers's FRAMA):

//@version=2

study("Fractal Adaptive Moving Average",shorttitle="FRAMA",overlay=true)

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)

L2 = lowest(low,len)

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))

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) + alpha*price

plot(out,title="FRAMA",color=blue,linewidth=2,transp=0)

I got these errors when loading on the chart

Here the correct version:

//@version=2

study("Fractal Adaptive Moving Average",shorttitle="FRAMA",overlay=true)

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)

L2 = lowest(low,len)

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))

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) + alpha*price

plot(out,title="FRAMA",color=blue,transp=0)

Just add in the formula.

out = (1-alpha)*nz(out) + alpha*price (just remove the spaces)
