The US stock market consists of multiple independently operated exchanges, each setting its own opening and closing times. However, most major exchanges operate synchronously. All trades are denominated in USD, with a minimum trading unit of 1 share.

Fee Structure: Manual trades incur approximately 1% commission; electronic trades range from 0.5% to 1%. Settlement follows the T+3 rule, meaning funds are available on the third business day after the trade.

The US market environment is mature, supporting three trading modes: regular trading (Monday to Friday, 9:30-16:00), pre-market (4:00-9:30), and after-hours trading (16:00-20:00). Investors can choose trading sessions based on their strategies.
