T+ 1 can be taken out after delivery, but it can't be received immediately, and it won't be received until the next day. Consistent with stock operation, arbitrage is to buy ETF and sell it in the primary market.

ETF fund transactions:

There are two ways to buy ETF funds. One way is to buy ETF funds through the secondary market (that is, on-site transactions) and use shareholder accounts or securities investment fund accounts. This method is equivalent to closed-end fund trading. The other way is through over-the-counter trading, which is equivalent to general open-end fund trading. If there is no shareholder account, it can be purchased with a securities investment fund account or redeemed with an open-end fund. However, the subscription and redemption of open-end funds must be handled at the business department where the account is opened. For online operation, please directly select the column of "Stock" and enter the corresponding fund code for trading.
