Automated trading systems are computer programs that execute trades in financial markets based on predefined criteria. These systems analyze market data, identify trading opportunities, and place orders without human intervention. They can operate 24/7, allowing traders to capitalize on market movements even when they are not actively monitoring the markets. These systems often use algorithms that incorporate various strategies, such as technical analysis or arbitrage. By automating the trading process, they aim to increase efficiency and reduce emotional decision-making. However, users must remain vigilant, as market conditions can change rapidly, potentially leading to unexpected outcomes.
