Adam,
While Metastock does not allow for a true nothing plot, it does allow for a
default plot. If the Gann HiLo were an oscillator we could simply default to
a zero line and have a positive plot in one color and a negative plot in
another. Since the Gann HiLo is an indicator we must choose another
indicator for a default. The possibilities are endless but I choose the
ZeroLag Ema as my default in the indicators that are shown below. Plot each
on a price chart with a separate color for each. You must also plot the
ZeroLag Ema on the chart in a third color. I named these indicators "visual"
because they serve as visuals only and would not work in an exploration or
system test.
BTW: I like your your expert adviser approach and believe that Daryl could
use either approach to fulfill his visual fantasies!
