Recent two trading days BTC review: the night before last, I set up short positions around 94000-94500, targeting below 91500 for take profit, and the results were precisely profitable. The key is not to be greedy and close the position, but to quickly switch to long positions in the 91600-92100 range. This wave of longs has already gained over 1000 points, a typical high-low switching strategy. Basically, it’s about catching the retracement at the high point to short, then turning around to go long at the support level during rebounds—timing is very important, you can't chase highs or get trapped. Currently, although BTC is experiencing significant volatility at this level, as long as risk and stop-loss are well managed, both bulls and bears have opportunities. The key still depends on the support and resistance levels on the 4-hour chart.
