hi guys
i saw in manual the printf return always a simple variable , but is possible return a series like this ?
Code
function run()
{
   BarPeriod = 24 * 60; // 1 day
   asset("EUR/USD");
 vars PriceHL = series(priceHigh() - priceLow());

var CellO = SMA(PriceHL, 48) + StdDev(PriceHL, 48);

   printf("Result = %.f\n", CellO);
   plot("MedianPriceOpenClose2", CellO, NEW, RED);
}

i tested but return me always 0 but if i plot i saw the line line
thanks at all
