Hi,

The code I got questions about is in the following picture:
Code:
function run()
{
	BarPeriod = 240;
	StartDate = 2003;
	EndDate = 2012;
	set(PARAMETERS);
	
	var *Price = series(price());
	var *LP5 = series (LowPass(Price,5));
	var *LP10 = series(LowPass(Price, optimize(10,6,20)));
	var *RSI10 = series(RSI(Price,10));
	Stop = optimize(5,1,10) *ATR(30);
	
	static int crossed = 0;
	
	if(crossOver(LP5,LP10))
		crossed = 3;
		
	else if (crossUnder(LP5,LP10))
		crossed = -3;
	
   if(crossed > 0 && crossOver(RSI10, 50))
	{
		enterLong();
		crossed = 0;
	}

	else if(crossed < 0 && crossUnder(RSI10, 50))
	{
		enterShort();
		crossed = 0;
		
	}
	else crossed -= sign(crossed);
	
	plot ("RSI", RSI10[0], NEW, BLUE);

}


First off, I didn't create this strategy. At Babypips, a guy called LiftOff did the first version of the strategy, and then JCL helped him with the version I linked above (correct me if I'm wrong).

To the questions:

Why do you use NumYears and StartDate?
The manual says "Number of years of the simulation if no StartDate or EndDate is given (default: 6 years)."

But in the code, there are both?

And if anyone please could explain the use of static int? And why we give crossed the value 3/-3? Why not 1 or 2 instead?

Thanks in advance!
