Fund T trading refers to the completion of trading on the trading day. Cross-border ETFs, bond ETFs, money fund ETFs and gold ETFs can be traded directly on the trading day, and the rest funds can be traded at T+ 1 Investors can only do T+0 operations in disguise, as long as the funds in the market can do T.
