Hello, the statistical time range of yesterday's inflow/outflow amount and quantity in ETF statistics is the previous trading day of US stocks.

Usually US summer time (March-November): Hong Kong time 21:30-4:00

US winter time (November-March of the following year): Hong Kong time 22:30-5:00

For example, the US stock market is closed on Saturdays and Sundays, and the data seen on Saturdays, Sundays, and Mondays are all US stock trading statistics on Friday.
