Four-hour technical analysis shows that the price has been under long-term pressure below the moving averages, indicating a clear weak trend. Although the MACD green bars have been gradually narrowing, they remain below the zero line in a bearish zone, forming only a short-term correction pattern without any substantial reversal signals. The KDJ lines are turning upward, but are strongly suppressed by the 50-level threshold. This rebound is merely a technical correction after an oversold condition and does not indicate a trend reversal.

Overall assessment suggests that after a period of low-range consolidation, the probability of breaking support is dominant.

Bitcoin: Expect a short position around 87800-88600 with targets at 87000-86000. If support is broken, continue to watch for further decline; otherwise, look for a long position. $BTC
