Hi jcl. I want to run some stats, plot some things, etc., w/o any trading. No indicators involved so I set LookBack=0. The code below gives an Error 046 - why? I can Ignore the Error 046 and the code executes. If I swap the comments so the 2nd series is also specified as 500 long, Error 030 results and the script does not proceed. Are either or both of these as expected?

Thanks.

Code:
function run() {
	BarPeriod	= 1440;
	LookBack		= 0;
	asset("EUR/USD");
	vars Price	= series(price(),500);
	vars Close	= series(priceClose());
//	vars Close	= series(priceClose(),500);
}
