K-line judgment: 1 hour 4-hour daily line If there is a big sunny line, then the more effective support is the bottom, middle and top of the big sunny line, which can be used as a reference, and the daily line is particularly important.
Boll judgment: the boll upper rail of hourly line, 4-hour line and daily line are all effective resistance in the near future, while the boll lower rail, as a limited support in the near future, is best combined with boll and 4 hours.
