  Nick,

  {Alerts}
  V1:=Input("Mov periods",2,500,200);V2:=Input("%

  {Top band}A3:=A1-(A1*(V2/100));    {Bottom 
  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.

    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,
