I am trying to use Add("VX 02-18", PeriodType.Minute, 1); so I can use this number. My main instrument is ES. Which I do have to change each expiration? So this may not be possible.
My question is if I have to enter the whole VX 02-18 as the data series. Do I have to change this value every time the expiration ends - so I would have to go in and change the VX 02-18 to VX 03-18 ??
Is their a way I do not have to do that? Something like Add("VX", PeriodType.Minute, 1);
It would be complicated to keep up with the current expiration???
thanks,
Dan
