From the daily level, the large bullish engulfing candle on March 11, accompanied by significant volume, indicates that the market may be entering a rebound phase. Additionally, the BTC futures have filled the gap below, further confirming a higher probability of a rebound. Therefore, the current trading direction is definitely to go long. Looking at the hourly level, it is still below the descending trend line, repeatedly testing the 85000 support-resistance switching position upwards, and the futures have filled the gap above, but the lows are gradually rising. The pattern resembles a cup and handle, but the trading volume is gradually shrinking. Thus, the current opening strategy is primarily to go long on dips, watching the downside levels of 82000 and 79000. If it breaks down and recovers while showing a strong candlestick, one can attempt to go long, with the stop loss set at the current low. There are a large number of stop-loss orders at the upper level of 86500, near the descending trend line, coinciding with the 0.618 position; bulls should appropriately reduce their positions or close them entirely.
