Last night, there was a double kill for both long and short, followed by a whipsaw. In the afternoon, after quickly hitting the bottom near 74400, there was a rapid rebound. The US market opened low continuously but couldn't stop the momentum. The current market data shows a clear rebound trend, but the repeated testing of resistance above is very evident, indicating that the market is only undergoing a technical fix. For intraday operations, adjustments should be made flexibly, and one shouldn't stubbornly cling to a single position.
