As the price falls, people continue to buy at the bottom, but the funny thing is that you can find that the funds for buying at the bottom come from small and medium-sized traders, not the so-called smart money. They will occasionally trade a sum of money (yellow) to reveal another error in their behavior, so we must pay closer attention to their behavior. Overall, they have not made a move yet. The funds of retail investors are filtered out because they are of little use to the overall price. When big funds are used to help retail investors, I will remind them.
