I love this question !
Suppose a function f, a condition Cond and here is a sexy b whenever
the condition is met.
f=StochD();Cond=Cross(f,30);
X=Cum(1);XMAX=LastValue(X)-1;
d=ValueWhen(Cond,xmax-x);y0=ValueWhen(Cond,f);
x0=xmax-d;
a=Param("a",2,2,5,1);
b=Param("b",2,2,5,1);
z=-1;
y=y0+sqrt(((a*b)^2+sign(z)*b^2*(x-x0)^2)/a^2);
Plot(IIf(Cum(1)>=xmax-d,y,-1e10),"",1,1);
y=y0-sqrt(((a*b)^2+sign(z)*b^2*(x-x0)^2)/a^2);
Plot(IIf(Cum(1)>=xmax-d,y,-1e10),"",1,1);
Plot((Cum(1)==x0)*(y0-b),"",0,2+8);
Plot((Cum(1)==x0)*(y0+3*b),"",1,2+8);
Plot(f,"f",2,1);
Play with parameters for the size.
