This type of box has a tower shaped bottom after breaking through the upper track, and a downward relay after falling below the lower track. Before breaking through, it should be played according to the potential downward relay to avoid unnecessary losses caused by being too aggressive, and do not dwell on what exactly it is? Whether it is a tower shaped bottom or a downtrend relay, the buying point of the lower track of the box during the oscillation process is consistent. The old idea proposed two weeks ago of breaking through the middle line of the buying game and rebounding based on the reserved space type is still unchanged. On the bearish side of the market, a slight increase in rebound space is enough, and at the major level, either a retracement of the potential downward trend of the relay structure box or a retracement of the market after the breakthrough, without chasing the local rise before the breakthrough. The long model mainly focuses on the low long of the lower track of the box, the low long of the lower track of the box, and the high of the upper track of the box. The short position is also exactly the opposite. Based on the specific structure stability, the one that comes out first should be done first. BTC
