If it continues to operate above 628 and does not break below 628 before 12 o'clock on Sunday night, the probability of an upward rebound is greater than the probability of a direct decline on Monday.

The top should be tested at a higher position, for example around 648.
Conversely, if it quickly returns to around 623 and is again suppressed by 629, then continue to defend and wait to see if it will continue to move downward.
In an upward trend, it is normal not to see a low top and low bottom; similarly, in a correction trend, it is normal not to see a high top and high bottom. If such patterns occur, the subsequent trend needs to be reassessed.
If there are no long positions around 623, waiting is actually a better choice. Once the trend is confirmed, entering the market later is not too late.
