Settlement Mechanism:
The US stock market implements the T+2 settlement system, which means that the liquidation and settlement can be completed on the third trading day after the transaction. However, the US stock market allows investors to trade T+0 when certain conditions are met.
When the account's net assets are between 2,000 and 25,000 US dollars, there are 3 T+ 0 opportunities within 5 consecutive trading days.
When the account's net assets are greater than $25,000, you can trade T+0 indefinitely.
