Tomasz,
How do we understand this equivalence ?
x=10+(Cum(1)%11);
is equal to 10 every 11 bars.
The
Wp=10;Plot(Wilders(C,Wp),"Wilders",1,1);
and
Plot(AMA(C,1/x),"AMA",7,8);
do not touch every 11 bars...
The same with Wilders(c,20).
See, for example the
x=10+(Cum(1)%11);
Wp10=10;Plot(Wilders(C,Wp10),"Wilders10",1,1);
Wp20=20;Plot(Wilders(C,Wp20),"Wilders20",1,1);
Plot(AMA(C,1/X),"AMA",7,1);
Plot(AMA(C,1/10),"AMA 1/10",4,8);
Plot(AMA(C,1/20),"AMA 1/20",4,8);
AMA(C,1/10) is 1-1 equivalent to Wilders(C,10).
On the other side, AMA(C,1/X) touches only by coincidence the Wp10 or
Wp20.
