High-Frequency Trading
High-Frequency Trading (HFT) is a modern way of buying and selling stocks and other financial products using very fast computers and special software. These systems can make thousands of trades per second, taking advantage of tiny price differences that might only exist for a fraction of a second. Think of it like having a super-fast robot that can spot and grab good deals in the market before anyone else can. This type of trading requires sophisticated technology, advanced mathematics, and deep understanding of financial markets. It's different from traditional trading because it relies on speed and automation rather than human decision-making.
