Based on the one-hour Ethereum chart, the price experienced a surge and pullback in the morning but failed to launch another attack above the 1600 level. Instead, the current price has moved to near the middle band of the key support Bollinger Bands. Combined with MACD indicator analysis, it is not difficult to see that a bearish divergence has already appeared. If the price later breaks below the middle band of the Bollinger Bands as support, it is highly likely to give back all of today's gains.
