when trading volume decreases what information can you get? whether you can see where the price moves from trading volume? up or down? I'm very confused.
I think the first thing you can know is whether to trade a coin or not is to look at the trading volume of that coin. The larger the volume, the higher the liquidity, the lower the risk. Therefore, it is very important to look at volume before trading.
I trade volume, not transactional information.
