Beijing time, real trading, when playing with this thing, you have to look at the hourly chart, then look at resistance and support levels. If the hourly chart fails to reach the resistance level, there is a high probability of a one-sided trend of a 30-minute decline. First, observe the 4-1 hour chart, and if the resistance level is broken, do not short. If the 4-hour chart shows an uptrend, be very cautious about shorting, because each bearish candle marks the beginning of an uptrend. #事件合约起飞中
