$BTC surge up then fall back, start paying attention to two short opportunities.

On the daily timeframe, there are signs of a top divergence; the price continues to push higher, but the upward momentum is not increasing in sync. In short-term price-volume behavior, after the spike higher, there is no sustained price expansion; instead, it quickly drops back, indicating that the buy support at the high level is beginning to weaken.

For the first short, watch around 85,700. Set a stop-loss above 86,100 and first look at the trend line near 84,000.

If the 84K trend line breaks down effectively, and the rebound does not reclaim it, then consider the second short, targeting around 82,400.

85.7K short → take profit at 84K first → if the trend line breaks, wait for the retest and short again → look at 82.4K.
