If you purchase new bonds on T day, you can check the matching number on the next trading day (T+ 1), and you can check the winning result on the second trading day (T+2) after purchase through trading → subscription of new shares.
New debt is convertible bond, which is a way of financing for listed companies. When a listed company issues bonds, investors can choose to buy new bonds. New bonds are not necessarily bought after subscription, but investors will be selected by lottery, and investors who win the lottery can buy new bonds at the issue price. Ordinary investors can sell the new bonds after listing and get the difference. However, it should be noted that it is impossible for new bonds to make money 100%, and attention should be paid to the risk of listing discount. The new bonds can also be converted into stocks in the future.
