The characteristic of an upward trend is that the price lows are continuously raised, and the highs are also continuously raised, with the price trend extending upward.
From the perspectives of time, space, and volume analysis, when the price is in an upward trend, the time of increase is long, and the time of decrease is short; the magnitude of increase is large, and the magnitude of decrease is small; during increases, the trading volume expands, while during decreases, the trading volume shows significant shrinkage. In an upward trend, the increase is the main direction, and every pullback in price is a good opportunity for investors to buy on dips.
