Algorithmic trading, also known as algo trading or quantitative trading, is the use of computer programs and algorithms to automatically make trades in financial markets. The algorithms used in algorithmic trading are designed to analyze market data and execute trades based on a set of predefined rules and instructions. These trades can be executed at high speeds and with high levels of accuracy, which allows traders to take advantage of market movements and opportunities that may be difficult or impossible to detect manually. Algorithmic trading is commonly used in stock markets, futures markets, and currency markets, among others.
