In the afternoon, the double-headed structure decisively entered the market, but the 87000 support was not effective; instead, it retreated to the entry point given in the morning. Currently, the support position has adjusted, and we are looking at the range of 86600-86400 given in the morning. If the middle band of the Bollinger Bands in the subsequent 4-hour level is also effectively broken, the previously formed double-headed structure may change. We need to rely on the middle band for support to return above 88000 and continue the previous upward trend.
