In the past two days, ETH has been experiencing evenly spaced pullbacks, with each day's rebound and retracement having similar amplitudes. This is not very friendly for those who are re-entering the market daily, as entering slightly early could result in a brief loss. The 4-8 hour chart shows a M-top structure, but the daily level remains strong. In the past two days, there has been a rebound after finding support around the 12-hour EMA 7: 4160. The support here is quite strong. Between 4330 and 4100, 4160 is the only strong support, while 4220 is weak support. Therefore, until there is a breakthrough above 4400, the ideal entry point for low buys is around 4160. If it falls below this level, the entry point would be around 4068. Currently, there is not much risk of a significant pullback, and for short positions, it is best not to chase below 4280, as a rebound could easily lead to losses.
