Trading listed shares or securities

If I incurred a loss in trading listed shares or securities, when i filled in the "Capital Gains Tax Summary" (SA108), my understanding is to fill in the loss in box 27. If I wish to set off any gains from shares trading for the tax year, 1) should I fill in Box 28? If yes, what code to apply? 2) do I need to fill in Box 48 as well for the loss in shares trading?

Hi Nella,
In year capital losses are automatically used against any in year capital gains even if it means you lose out on the annual exempt amount.
Thank you.
