Custom future for IBEX from IB  [SOLVED]

Hello.

I´m triying to build a custom future in MC for the IBEX instrument with data provided for Interactive Brokers.

I manage download / plot each future from IB without any problem:
But when I try to build the custom future, in the IB list I don´t find the ticker for this symbol (M3F):
What could be the problem? Could anybody help me?

Thanks in advance.

Please open QuoteManger,

right click on one of the symbol you want to use in the custom future,

select Edit Symbol....

What is listed under Symbol Root?

Thanks TJ.

I have checked symbol root and is 'IBEX':
But it doesn´t appears in the list also:

They can sort this out for you.

Hello andriuking,
Our Symbol Dictionary contains symbol roots for most futures contracts but the list is not 100% complete. To add a new symbol root please go to Tools => Symbol Dictionary => Choose Interactive brokers => click "Add".
