Just now, this needle liquidated short positions around 70, but the move was too fast and not very good. On the 4-hour and daily charts, the current formations are still okay, and with 27 minutes remaining, there's no problem with the daily candle closing bullish.

The smaller time frame pattern has been broken, mainly focusing on the 70240 level. If the 4-hour close drops below this, the probability of going back to find a bottom near 690 increases. It currently looks like buying support is still holding, but how long it can last is uncertain.
Calculating the time, this rebound probably isn't over yet; let's keep observing.
Every time there's a needle insertion, it's a good opportunity to reduce positions on both sides. Adjusting your position properly is the top priority.
