operator '/' cannot be applied to operands of type.....PriceSeries

[trader3000a]

Hi,
How can i revise to avoid the error?

else if (State == State.Configure)
{
AddDataSeries("ES DEC23", BarsPeriodType.Day, 1);
}
}

protected override void OnBarUpdate()
{
ESvol = ATR(Closes[1], Period)[0] / Closes[0];
Symbolvol = ATR(Period)[0] / Close[0];

Value[0] = Symbolvol / ESvol;
}​

Hello trader3000a,

Please provide the full error message (or a screenshot).

May I confirm ESvol and Symbolvol have both been declared as doubles?

Hi,
Yes, I declared them up top

Hello trader3000a,

Closes[0] is a price series.
Close[0] or Closes[0][0] would be a double.
