For example, 94600 has broken the high point in 30 minutes, so a 4-hour rebound is established. What you need to do is wait for a 30-minute retracement within the 4-hour period without breaking 91000 and buy more. The target is 98000-99700. Then the long position you made belongs to the last 30-minute level in the 4-hour rebound. Do you understand this? Then there will be another 4-hour decline to break 91000, so 91000 must be broken to complete the daily decline structure. Some nitpickers will say that 91000 cannot be broken, so if you say it cannot be broken, then it will be broken.
