Today it rained all day and I read a book. There's a chapter that is very interesting!! Combining with the recent market, I've been wanting to improve this order-following data, but recently the market direction has been unstable. Not opening orders for a long time makes me afraid that people will leave, and opening orders might result in small unrealized losses. Others might follow halfway and run away. Actually, I can't make much money either. I just want to do one thing well, which is always afraid that others will lose patience and leave after losing money, making my heart restless and uneasy.
