Key Notional in
Fwd Contract refers to an optional number of units of the underlying tradable defined in Underlying
If omitted, the default is 1.
Note that the underlying tradable may itself define its own notional.
For example, if the
Underlying is a USD bond with a notional of 1,000,000 and the notional here is set to 2, the forward contract references effectively a USD bond of a notional of 2,000,000.
