At noon, Bitcoin rebounded from the low of 101400, unable to continue the downward trend, reaching a high of 102900 before retreating under pressure, currently trading around 102800. Overall, it has formed a short-term oscillating upward structure, with no breakout of the high. Ethereum rebounded from the low of 2414, reaching a maximum of 2479, and is currently trading around 2462.

From the current trend, the four-hour chart shows a clear bottom oscillation pattern. If subsequent candlesticks continue to oscillate sideways within this range, it will help digest the volume for the Asian session. At the same time, the lower Bollinger Band still shows a downward trend, indicating that the overall market still has room for correction. Looking at the short-term one-hour chart, KDJ shows a golden cross, and MACD shows a bottom divergence, indicating a certain rebound momentum in the short term. However, the Bollinger Bands have entered a contraction phase, with the upper highs continually moving downwards, and the short-term downward channel has not yet been broken. Therefore, after the rebound, caution is still needed for a potential pullback. The operational strategy is primarily focused on short positions.

For Bitcoin, short positions can be arranged in the range of 103000-103500, targeting around 100700; for Ethereum, light short positions can be tried between 2470-2490, targeting around 2410.
