how to make a variable in EA which is only affected for each symbol (chart)

[Irwan Adnan]

What I mean is if we attached the EA to many charts, calculation of the variable (say "myvar") of one chart does not related to the calculation myvar in another charts.

 for exmpl :

int myvar;
for (i = 0, i < 10, i++)
{
  myvar = myvar + 1;
}

so myvar calculation is : 0, 1, 2, 3, 4, 5, 6, 7, 8, 9

 

or should we use an array to myvar so each symbol have their specific variable.

An EA running on 1 chart is totally independent of other EA on other charts, even if it's the same EA.

Well, thank you friend. You make it clear. I was thingking that, because calculation result in my EA is not as my expected. My stupidness. It must be something wrong with my code logic.
