Yesterday, the Federal Reserve decided to keep the interest rate unchanged. Powell's words were dovish, but he continued to play Tai Chi, so it had little impact on the market. Yesterday, the market hit the 3350 trend line pressure and began to fall rapidly, which is consistent with the short selling near 3360. The market has now reached the 4H large-scale trend line support position, and the support here is relatively strong. At the current price of 3160, you can consider going long, and the short position is chosen near the trend line pressure of 3280. #美联储何时降息？
