After reading that Teacher P seems to have been playing with contract small orders recently, it's time to talk about something. The purpose of Ant Group is to test market sentiment, so don't be influenced by Ant Group's own profit and loss. If one's emotions are affected by the profit and loss of an ant order, then the meaning of opening an ant order will be lost. Testing liquidity with a certain amount of funds (real market liquidity+market making liquidity) requires strict development of a quick exit plan (unrelated to profit or loss).
