Returns the underlying instrument of an option or Nothing if no underlying instrument is available.

Underlying instrument represented as CQGInstrument Object

Mainly this refers to underlying instruments of options. Designed so the CQGInsturment object containing the underlying instrument will be returned only if it was previously and separately resolved. Otherwise, the property will return Nothing.

Nothing is also returned if the instrument is not an option.

To access the Instrument properties see the example section of the InstrumentSubscribed event.
