This is perfectly feasible with EL.
Once you got the pivot point ( a few bars later after it occured), write the
values of the parabola into an array ( knowing the parabola equation, this
is not a problem)
Then use the backplot TS feature to display the parabola from the vertex to
the first known point when it is known,using the array value. Then update
the next plot from the equation until a new swing is found.
