After the opening, the price surged, then fell below the average price line. When the price rises again near the average price line, it encounters resistance, which can be used as a basis to enter a short position. Each time the price line rises near the average price line and faces resistance, it presents an opportunity for investors to enter a short position. However, it is essential to combine this with other technical indicators and use them in conjunction; relying solely on the average price line and price line has a low probability of success.
