On the 7th day, it's still stable. With 500u in quantitative trading, although the returns are not high, there is still a return rate of over 10% in a month. This is more stable than any investment. Many people ask how I sell the robot. I am not selling the robot; this robot is installed for free. If everyone wants to use it, I can share it, but it's best to wait for me to test it for a month before doing so. If anyone wants it now, leave your WeChat ID, and I will find time to add you. Then we can create a group chat to discuss together.
