Generally, the intra-day band operates at 30 minutes or 15 minutes, the multi-day band operates at 60 minutes or 120 minutes, and the multi-week band operates at the daily line.

Operating a certain band depends on whether all the general trends in this band are up or down. Generally, a band will run above the line 12 or 13, and of course it will encounter shocks. At this time, for example, in the 30-minute band, the trend can generally be judged by the deviation of the trend within 5 minutes, the change of the disk surface, and the MACD and BOLL lines.
