Execute a function call only once at the Daily Open

[erickva]

Hi All,

I am not very familiar with Empty4 and I am struggling to find a way to execute a function call once we have the start of a new Daily bar. I want to execute it only once.

I can make it inside the start() and check if I have a new day, but would be a ridiculous loop for something that can probably be done in one line, by a more experienced Empty4 programmer.

So, if someone can help with this one I will appreciate.

Thanks,
Erick

Eg.

Code: Select all

static int D1Bars;
   if (D1Bars != iTime(NULL, PERIOD_D1,0) )
   {
     ... your code here
   }

static int D1Bars;
if (D1Bars != iTime(NULL, PERIOD_D1,0) )
{
... your code here
}

Hi dietcoke,

Thanks very much! Exactly what I was looking for!
Guess I just have to update D1Bars anytime I go through my code, so it will run again next day, if it is inside the start():
D1Bars = iTime(NULL, PERIOD_D1,0);

Thank you!

Don't forget to set D1Bars = iTime(NULL, PERIOD_D1,0) within the loop. You'll probably also want to add a test to make sure you aren't starting your EA in the middle of the afternoon.

What I've done in the past is check that TimeDay(iTime(NULL,PERIOD_M1,0)) != TimeDay(iTime(NULL,PERIOD_M1,1)). This makes sure that we've entered a new day, and will only trigger in the first minute of the day.

Brilliant George, thanks a lot!
