Algorithmic trading, or algo trading, uses computer programs to automatically place buy and sell orders in financial markets based on predefined rules and strategies. These algorithms can process market data, price trends, technical indicators, and even news in real-time to make swift trading decisions.
Traders or institutions set the algorithm to follow specific criteria—such as timing, price, volume, or a combination of conditions—and the system executes trades without manual intervention. This ensures speed, accuracy, and efficiency, reducing human error and emotional bias.
Common strategies include trend-following, arbitrage, mean reversion, and market-making. Algo trading is widely used by hedge funds, mutual funds, and large financial institutions, but it is also becoming accessible to retail investors through broker platforms.
