looks like Aval will be resetet to 0 every time you run in the method.

What you're asking for doesn't make sense.
Can you rephrase it?

As it is hard to determine if you are struggling with a logic error or syntactical error.

double available; //zero is the default
double difference;
double sod;

if (AccountEquity()!=0)
{
	sod = AccountEquity()/Goal;
}
else
{
	//deal with it...
}


if (sod >= available) 
{
        available = sod;
}
else 
{
        difference = available - sod;
}

double available; //zero is the default

Zero is not the default. There is no default.

1. There is no default in MT5

   If a variable is not initialized explicitly, the value stored in this variable can be any. Implicit initialization is not used.

2. There is no default in MT4 when you use strict (which you should always use.)
