Timeframes
The same stock can have different counts on different timeframes
Two counts on one listing can both be right. They are different bars. The clocks below are the app’s China A-share session, Asia/Shanghai, on a regular weekday. They are not a full exchange rulebook.
How a 120-minute bar is built
The app builds 120-minute bars from 60-minute bars. Two bars on the same date whose timestamps are 60 minutes apart become one bar: the first open, the higher high, the lower low, and the second close. The 120-minute timestamp is the second bar’s timestamp, the end of the pair, not the start. If the next timestamp is not exactly 60 minutes later, the current bar stays by itself. On the iPhone chart, a final unpaired 60-minute bar is kept as its own bar. The close scan’s 120-minute frame keeps that leftover bar only when its clock is the market close, or one minute before lunch; otherwise that tail is dropped. This article does not state an A-share half-day schedule.
A regular A-share weekday in the app
- Open is 09:30. The app treats 11:31–13:00 as lunch. Continuous trading ends at 15:00. The app’s settle buffer runs until 15:08, so the after-close daily scan has not started at 15:04.
- At 12:00 the daily bar is not closed. A 60-minute bar timestamped 11:30 can already be closed. 13:00 is 90 minutes later, so those two bars are not paired into one 120-minute bar.
- Teaching closes, not a quote: 60-minute bars at 10:30 and 11:30, closes 10 then 9, become one 120-minute bar timestamped 11:30 with close 9. That count is not the daily count.
60-minute and 120-minute views are Pro. Today’s after-close list is the daily count for the hot list and watchlist. Do not copy one timeframe’s count into the other column.
