  Alerts & my first AFL attemptI have a number of 
  mechanical trading rules which I'd like to incorporateinto AB.For 
  example: Take PREV CLOSE, multiply by 0.35 then divide by 100.  Add 
  thisto PREV CLOSE and BUY when next day crosses above. Subtract this from 
  PREVCLOSE and SELL when next day crosses below.Rather than doing 
  all the math manually, I'd like to incorporate this intoAB as an 
  alert.  I have two formulae so far:Buy = Cross( Avg, 
  Close+Close*0.35/100 );Sell = Cross( Avg, Close-Close*0.35/100 
  );Does that "say" the same as my description above ??  If so, 
  what do I donext to incorporate this as an alert
