Watching the four-hour candlestick chart, the candle moves towards the EMA trend line and tightens at the resistance level of 91000, the price encounters strong resistance, then gets suppressed and bounces back to the EMA support level of 87700. This oscillation between the resistance level and the support level should be noted, as fakeouts are very common. Whether the price breaks through the resistance level or falls below the support level, as fakeout can lead to a quick reaction, the Bollinger Bands remain sideways, the candle consistently stands near the middle line of 88000, operations should use resistance level and support level as a guide for short-term thinking.
