Hi 


I would like that each time there is a new bar formed,

my EA checks some instructions.


So I wrote that:


count1 = iBars(NULL,PERIOD_D1);
count2 = count1;

while (etape == 0) 
        {
        count1 = iBars(NULL,PERIOD_D1);
        if(count2 =! count1)
                {
                if (cond1)         
                          {
                           etape =1; // we move to the next step
                          }  
                else
			 {
                          count2= count2+1;
                          } 
		}           
         }      


But I keep wondering if should not have used a loop "FOR".

I thought of something like that:

for(count=0; count<10; count++)
   {
    instructions;
   }

But the problem with the loop FOR, how could I make sure that each loop correspond to 1 day.

So that every instruction is only check when a new bar is formed?


Thanks for your help in advance.

You could use a static to avoid the loop. This works with repeated calls to OnTick(). Like this:

static int barcount=-1;
int count=iBars(NULL,PERIOD_D1);

if(count!=barcount && barcount!=-1) OnNewBarD1();
barcount=count;

Hi, thanks for your reply.


I don't understand what is "OnNewBarD1();"

It is not a function of mql4.. so i am a bit confused

It's a stub/placeholder for you to fill in.
