What are trading systems?

Trading systems are sets of rules or algorithms designed to automate or guide the process of buying and selling financial instruments such as stocks, bonds, or derivatives. These systems can be manual or fully automated, and they typically use technical indicators, quantitative models, or predefined strategies to make trading decisions. Trading systems aim to remove emotional bias, improve consistency, and increase efficiency in the financial markets. They are widely used by professional traders, hedge funds, and financial institutions to manage risk and capitalize on market opportunities.
