There is no problem with Linearray() function inside a for loop.
Enjoy the example in your Indicator builder :
x=Cum(1);
z0=LastValue(Cum(1))-160;
x0=0;y0=0;x1=0;y1=0;R=30;
DIS=50;MAg=10;Coeff=0.5;Cc=0;
for(i=BarCount-200;i<BarCount-10;i++)
{
x0[i]=i;
y0[i]=sqrt(R^2-Coeff*(i-z0)^2)-5;
Plot(LineArray(x0[i],y0[i],x0[i]+dis,MAg*y0[i]+dis,0),"",colorRed+Cc%
2,1);
y1[i]=-sqrt(R^2-Coeff*(i-z0)^2)-5;
Plot(LineArray(x0[i],y1[i],x0[i]+dis,MAg*y1[i]+dis,0),"",colorRed+Cc%
2,1);
Cc=Cc+1;
}
Plot(y0,"",colorRed,8);Plot(y1,"",colorRed,8);
Plot(dis+Ref(MAg*y0,-dis),"",colorBlack,8);
Plot(dis+Ref(MAg*y1,-dis),"",colorBlack,8);
