The reason for shorting at present is very simple. Although it is currently stabilized above the long-short dividing line of 28,800, it has fallen back after a small breakthrough of the previous high. In addition, judging from the market data, the first wave of pull-up tonight is a counter-driving force formed by the stop loss of the short position at the support level below. And there is a bearish divergence at the small-level high. So I first entered a small position to test the waters. If the stop loss is around 29,500 or the daily closing is above 28,800, I will consider closing it and take part of the extra profits to try. It is extremely difficult to touch the top on the left side. It is recommended to wait until the CPI comes out on the evening of the 12th before doing it. The direction at that time may be more accurate. The potential pressure above is 29,300-29,500, and the 29,900 weekly level vertical supply column pressure level.
