[amibroker] Parabola() ZScore() Conversion

["Mr Valley" <valleymj@xxxxxxxxxxx>]

All,

2 Questions:

1.) In AB/AFL, how does one code plotting a parabola
    with the Vertex = ref(c,-20); and extending to the right, reflecting a
width of say, 1 * Stdev(c,20).
    So, beginning at ref(c,-20); and extending to the right to current
close?

2.) How does one convert a ZScore() to probability in AFL as a Function()
rather than using a Lookup Table?

Thanks in Advance,
Mr. Valley
