$BTC The second one maintains a range-bound oscillation pattern throughout the day, with bulls launching a rally at noon, pushing the price up to around 1733. After the surge, the bullish momentum could not be sustained, and the market began to slightly retreat, with a current pullback of 20 points, indicating a short-term oscillation correction.

From the 4-hour Bollinger Bands structure, the lower band is turning upward, the middle band is flat, and the upper band is still trending downward. The bullish and bearish forces are relatively balanced, with no clear trend signal, so the overall outlook remains a wide-range oscillation.
The trading strategy mainly focuses on buying low and selling high within the oscillation, with light positions near the support zone of 1670-1690 to gamble on rebounds, and short positions near the resistance zone of 1735-1750 to bet on pullbacks. Until the range is effectively broken, no clear trend will be confirmed. If it breaks above 1750, then go long with the trend; if it falls below 1670, the oscillation pattern is broken, and the strategy should be adjusted accordingly.
