A person is having a speculative income of say Rs.800000, he is having a carry forward business loss of Rs.500000,

Can anyone tell me whether this can be set-off, I know that the speculative business income can be set-off for the same year Ordinary Business Loss but i dont know whether the same could be for the carry forward business loss. It is given in the text  book that the carry forward business loss can be set off only against business income. But it is not mentioned as Ordinary Business Income.

Could any one please give me a confident answer because this is for a real situation to file the IT Return.
