The emotional aspect of trading, when quantified, is essentially flow. The market allocates funds to whom, and the characteristics of these funds reflect changes in flow. Short-term flow indicates that funds will move on, while long-term flow indicates whether funds are increasing or decreasing. The overall market flow represents the allocation weight of funds. It involves whether the allocation is incremental, oscillatory, or contractionary. The overall amount of funds in the market is influenced by long-term policies and short-term information. So, do you understand Ethereum? The trend of ETH is essentially a logic of capital flow.
