Main shipments generally show negative net inflows of funds.

In financial terms, the calculation formula for net outflow of funds is: incoming funds - outgoing funds. A positive value indicates a net inflow of funds, and a negative value indicates a net outflow of funds. The trading volume when it rises is counted as inflows, and the trading volume when it falls is counted as outflows. Money Flow is a mature technical indicator internationally. The calculation method is very simple. For example: in the minute of 9:50, if a certain sector index rises compared with the previous minute, the transaction volume of the minute of 9:50 will be counted as capital inflow, and vice versa. Fund outflows will not be included if the index has not changed compared with the previous minute. Calculated every minute and totaled once a day, the difference between inflows and outflows is the net inflow of funds for the sector that day.
