OK, then this is what you want, it only discriminates changed fractal
levels, not necessarily higher than previous, but that can be handled by
changing to X1>X2:
X1:=Fml("up fractal");
X2:=ValueWhen(2,Cross(HIGH,X1),X1);
Cross(HIGH,X1) AND X1<>X2
WPI signaled on 5/6 and 5/15 in May. Not familiar with William's hybrid
moving average (aren't you relieved) <G>
