In case someone else has the same issue, this piece of code does the trick.

Code:
function run()
{
	StartDate = 20100101;
	BarPeriod = 1440;

  vars Close = series(priceClose());
  vars SMA100 = series(SMA(Close,100));
  vars SMA30 = series(SMA(Close,30));

  
  string Format = "n%04i-%02i-%02i %02i:%02i, %.10f, %.10f";
	
	
file_append("JC2.csv",strf(Format,year(),month(),day(),hour(),minute(), Close[0], SMA30[0]));
