T+D trading mode is not common, and it can generally be seen in the stock T+ 1 (the position will be opened on the same day and will not be closed until at least the next trading day).
T+D usually refers to the deferred trading business of physical precious metals in Shanghai Gold Exchange.
This is also the only formal and legal spot investment in China at present, with leverage ranging from 5 to 7 times.
T+D has various banks as agents and directly opens accounts in banks.
In foreign exchange, those with leverage higher than 20 times are not protected by domestic laws.
