#美联储回购协议计划 Today, I tracked a good opportunity intraday—short at the 4513 level, then successfully exited at 4508. The entire operation yielded a profit of 5 points.

From a macro perspective, the Federal Reserve's liquidity movements are always a key factor influencing short-term trends. Although these intraday fluctuations are not large in magnitude, as long as the rhythm is right, the efficiency can be quite significant. Continue to monitor key support and resistance levels, waiting for the next signal to appear.
