Basic Alerting EA

Inserted Code
double bars             = 0;
extern double value     = 0.0000;

int start()
  {
   if (Bars>bars)
   {
      bars=Bars;
      
      if (Open[1]>value&&Close[1]<value||Open[1]<value&&Close[1]>value)
      {
         Alert("Trend Change at Symbol()");
      }
   }

   return(0);
  }

This simple EA is supposed to alert me if, previous bar price crosses a preset level in either direction. Say preset level is 5 and in the Previous bar the open was 2 and the close was 9. It crossed 5. The previous bar's open and close was on either side of the preset value of 5. Its should alert me (crosses in either direction).

It doesn't seem to work. I tried like 8-9 times. Someone please help ?

PHP Code
double bars             = 0;
extern double value     = 0.0000;

int start()
  {
   if (Bars>bars)
   {
      bars=Bars;
      
      if ((Open[1]>value&&Close[1]<value)||(Open[1]<value&&Close[1]>value))
      {
         Alert("Trend Change at ",Symbol());
      }
   }

   return(0);
  }
For one thing, the input on the alert is incorrect, although it shouldn't keep it from sounding. It will just display the Symbol() as text, instead of the actual symbol.

I also added parenthesis to the statement above that, as this a compound statement and this is typically how it's done ... or, at least I know it helps. If it were a series of "&&" statements or "||" statements (instead of a combination) then it wouldn't matter.

Of course I can't say that this is all that's wrong with it but, it's worth a shot.

I updated the code, it gives the proper alert now, but rather randomly. It didn't wait for the bar to close before alerting me. I'll wait and see till the next bar closes.

Thanks !!!
