We are now in the era of AI artificial intelligence. Don't cling to manual trading anymore; human energy is ultimately limited. You need to learn to use technology to assist in monitoring the market. AI quantification is still in its developmental stage; if you want to make money, you need to stay ahead of others. Don't wait until everyone is using AI quantification and it's everywhere before you join the crowd; by then, you might not even get a share. Just like in physical businesses, you need to seize opportunities and stay ahead of others. Don't wait until everyone is selling their houses before you realize you should buy one.
