what symbol to use for USdollar index in livecharts?

[christineesq]

I have tried CECX00Y, DX A0, DX H8, DX #OI,
DX #V US DOLLAR CEC Future
DX #F US DOLLAR CEC Future
DX Z7 US DOLLAR CEC Future
DX M8 US DOLLAR CEC Future
DX U8 US DOLLAR CEC Future

and yes with the CEC: in the symbol

anytime there is a space in the entry - gets truncated and ends up being CECX and no chart

anyone know of a working symbol? oh and by the way yes I am paying for delayed
