#数字资产市场动态 January 21 $BTC $ETH Short-term Technical Analysis and Trading Ideas

Recent days have seen significant market fluctuations, and tonight BTC and ETH have shown many interesting technical signals.

From the 4-hour chart of BTC, the price successfully stabilized after touching the lower Bollinger Band, which is a typical oversold rebound signal. The KDJ indicator has already turned red in the extremely oversold zone, and the J line has crossed above the K and D lines to form a low-level golden cross, indicating that the short-term selling pressure has basically been released and the bullish momentum is gradually building. The Bollinger Band is narrowing, indicating that volatility is contracting, and the price is expected to recover along the lower band. If this level holds steady, the upward resistance should focus on the key level of 92,000.

ETH's performance is highly correlated with BTC, and the short-term stabilization pattern is also quite clear. The joint strength of these two assets often signals the brewing of a rebound rally.

From a trading perspective:

— $BTC can consider building long positions in the range of 88,300-88,800, with the upper target focusing on the resistance zone of 90,300-92,000.

— The rebound opportunity for $ETH in the 2910-2940 range is also worth participating in, with upside potential targeting 2990-3060.

Of course, these are just ideas based on the current technical analysis; specific operations should be flexibly adjusted according to real-time market conditions.
