What is the size of a contract in trading?
Could you please clarify for me the concept of contract size in trading? I'm trying to understand how it factors into my trading decisions. Is contract size a fixed quantity, or does it vary depending on the asset being traded? Also, how does contract size affect the potential risk and reward of a trade? Is there a standard way to calculate the appropriate contract size for my trading strategy? I'd appreciate any insights you can provide to help me better grasp this aspect of trading.
