ETH is encountering resistance when it goes up, is the double top going to form? Brothers, ETH has reached 3940 in this wave, but it has obviously reached the top. Now we should not only guard against chasing highs, but also guard against possible double top structures! In terms of form, the daily double top is obvious: the previous high was 3940, and this wave of highs reached 3940 and then pressed down. The neckline support is about 3700. Once it falls below, the double top is established and the downward space is opened. The K-line signal is also weak, with long upper shadows in 4 hours, especially the K-line on July 28, from 3888 to 3806, indicating that the selling pressure in the 3800-3900 area is very large. In terms of MACD, the 4-hour has already formed a dead cross, and the daily column has also shrunk for 4 consecutive days; the RSI 4-hour has fallen from overbought to 45. Although the daily line is still at a high level, it has turned downward. EMA moving average does not support the current price. The 4-hour price has fallen below EMA7 (3799), while the daily EMA30 is still at 3298, so there is a lot of room for medium-term correction. The volume structure is not good either. When the price fell in 4 hours on July 28, the transaction volume was as high as 1.93 million U, far exceeding the average, which is a large-volume decline. On the contrary, when the price rose, the volume could not keep up, which is a typical "price increase and volume reduction". Funds began to hesitate and dared not chase. 3650: The previous low + integer level + EMA support overlap, which is a good bargaining position. 3600: The typical double-top structure callback target position, superimposed with the integer level, the opportunity is more stable. Stop loss: 3570, do not hold hard if the previous low is broken. The overall market is not weak now, but the rhythm of ETH has begun to be weak. It is risky to chase high, so it is better to wait for the key position to buy low. Remember: Only those who can survive the shock are qualified to eat the main rising wave.
