Mike,
1. it is the equation of a circle. The radius is small [R=1] and it
appears like a rhomboid.
2. You may mark all peaks/troughs with the
x=Cum(1);
per = 5;//Sensitivity
pR = PeakBars( H, per, 1 ) == 0;
x01= ValueWhen( pR, x );
y01 = ValueWhen( pR, H ) ;
Plot(C,"",1,64);
y0=y01;x0=x01;
Plot(IIf(x==x01,y01+0.02*abs(y01),-1e10),"",4,8);
TpR = TroughBars( L, per, 1 ) == 0;
x01T= ValueWhen( TpR, x, 1 );
y01T = ValueWhen( TpR, L, 1 ) ;
Plot(IIf(x==x01T,y01T-0.02*abs(y01T),-1e10),"",5,8);
If you have some fixed period in the past, you should express it via
the respective x=cum(1)
C1=condition;
t1=valuewhen(C1,x);
and then ask
Plot(IIf(x==x01 AND x>t1,y01+0.02*abs(y01),-1e10),"",4,8);
