should this be a error?

CFAI R48, EOC question 1

  • the value of the future is negative, why does short make a payment to the long if he wins?

it is not. there was something about this, if memory serves me right … [a special term for this type of forward contract – which I am not able to remember right now].

Off-market FRA.

The value of the future is negative so short have to pay to long position for holding this contract
