band}Alert(C=A2 OR Cross(A2,C),1); {Top band contact OR
crossing}
-Alert(C=A3 OR Cross(C,A3),1); {Bottom band
contact OR crossing, minus sign in front makes it easier to see
plot}
0.1% might be too tight. I would try ~5% shift.

Subject: Formula help
I wonder if anybody can give me a clue as to how
to achieve the following:
I have plotted a 200-day exponential moving
average, and also:
* above it, the same MA but with a vertical shift
of 0.1%
* below it, the same MA but with a vertical shift
of 0.1%
This obviously creates 3 parallel
bands.
I want to set up an alert that fires when the
price touches or drops below the top band, and another that fires when the
price touches or rises above the bottom band.
All suggestions welcome.
Many thanks,
Nick
