Secondary level of 4 hours, the closing price has fallen below 3942, the exchange rate has also fallen below, forming a high hanging reversal, high 4 is established, with upper resistance levels at 3960 and 3986 (which are also daily level resistance), if the rebound does not break, it will continue to decline, with lower support levels at 3910, 3880, and 3830 (which are also daily support levels).
3846 is the head and shoulders line for high 3 and high 4. If the closing price cannot hold here, I will provide a few further support levels, 3760, 3630, and 3500 (the latter two can be used for pending orders to receive spot, also daily level C point support).
For those trading contracts, please be sure to control your position well. Tomorrow morning's daily closing is quite crucial. If the closing price breaks through 3986, combined with the interest rate decision at 3 a.m. on the 19th, there may be a spike upward, with resistance levels still around 4100, 4150, and 4270.
In the cryptocurrency market, there are no absolutes, always respect the market and be prepared for both scenarios.
