I use 
real-time "1 minute" data and yes, it is the last minute. I'm not sure about 
tick level data...

  Oh I meant to say - this is with Realtime data ... so it's 
  each tick not todays closing price..... or is each tick regarded as 
  a close ?

      [amibroker] AB 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 ?R.Send
