High-Frequency Trading
High-Frequency Trading (HFT) is a modern investment approach where computer systems make extremely fast trading decisions within fractions of a second. Think of it like having a super-fast robot that buys and sells stocks automatically, trying to make tiny profits many times per day. This is different from traditional trading where humans make decisions over longer periods. Companies use specialized computer programs and high-speed connections to gain an advantage in the market. You might also hear it called "algorithmic trading" or "automated trading systems."
