After two months of rebound, bitcoin's current weekly trend is shown in the figure, forming a standard high box, which is relatively easy to grasp.A high before the higher breakthrough, means the formation of a new bull market, a lower breakthrough before the low, means the beginning of a new decline. In theory, the high box upward breakthrough is a high probability, but here it should be noted that if the current rebound high can not break through the high in April last year, it is possible to form the head and shoulder top shape.Therefore, there is a certain probability of forming both forms of head and shoulder roof or box. Of course, the current macd gold fork, good for the bulls.No matter what the future goes, once the trend is formed, it will continue. So if you want to do more heavy warehouse, you should be in the breakthrough before the high, that security is much higher, and want to sell short, should also be in the break below the lower edge of the box, so that the certainty is better.
