The game of the market is essentially a game between funds and chips. If there are more people who want to buy chips and fewer people who sell them, the price will rise. If there are more people who want to sell chips and fewer people who buy them, the price will fall. If there are more people who want to sell chips and more people who want to buy chips, the trading volume will increase sharply, resulting in differences; if the willingness to buy and sell chips is low, the trading volume will shrink and fluctuate. The market will be tepid, forming a deadlock or freezing point. If there is any increase in volume before, it will rise, and the rise must be driven by a large volume. In fact, this statement is a bit simple, because there must be a sale for every purchase. If you open a short position, someone must open a long position before you can trade. There are opponents at all times, that is, the trading volume is large, but the differences are large.
