Daily market analysis - $BTC

The reference period is 2H. The overall trend is upward, but in the short term there is a "high and low points are getting lower and lower" downward structure. My current idea is that the price may return to the gray area below to test the support.

Then when the price returns to the gray area and rebounds, it is a chance to re-enter the airport for long orders. If the price falls below the gray area, it means that the upward trend is facing a change, and I will give a new target later.
