The boss will still return to 117000. The second one should focus on whether 4715 can break through. If it breaks, it will go up; if it doesn't break, it will break the previous low. Once the direction is determined, it becomes simple to operate. If it goes down, short at high points; if it goes up, go long at low points. The second one has shown an independent market trend, but overall it is still a downward trend. In terms of operation, short at high points. Short at 4710 for the second one. Go long at 4320 for the second one. Whether up or down, it should challenge a few times; the intermediate price highs and lows can also make money, provided that you can hold on.
