At 3 o'clock in the afternoon, the market suddenly entered a pullback mode, directly falling below the middle track of the Bollinger Bands, very clean and neat, indicating that this decline was caused by sudden selling pressure.

Thirteen examined all the data and news, and it was difficult to find a reasonable explanation for this decline.
However, as we have mentioned in the past few days, the current market is still in a period of volatility, and it may remain volatile until the eve of Trump's inauguration. Everyone needs to be mentally prepared.
However, this is also a good opportunity to sell high and buy low.
