Price surged and fell back, showing clear signs of peak volume. Just from the 15-minute chart, it is easy to see the short-sell signal from the price's high volume surge and the downward break of the moving average.
Here, I remind all students that if the price on the 15-minute chart does not break the moving average after surging and falling back on the same day, and then the price breaks the moving average on the next day or during the night session, this short-selling method is still applicable. When trading, you can analyze the market by connecting the trends of several days' 15-minute charts.
