Trend is the direction of market movement, whether the peaks and valleys gradually rise, gradually decrease, or move horizontally. Upward trend: The high point is getting higher and the low point is also getting higher, like climbing stairs step by step. Downward trend: The high point is getting lower and the low point is also getting lower, like stepping down a step by step. Trend trading follows three steps: first look at the direction, then find the entry point, and finally determine the exit strategy, all of which are indispensable. Seize the rebound during the mid-term decline, wait for the coin price to break through the short-term downward trend line before entering, but be quick to enter and exit, and set a stop loss. A pullback in the mid-term uptrend, when the coin price breaks through the short-term downtrend line, is a signal of the end of the pullback and can be increased or bought. After the mid-term decline ends, if the coin price breaks through the downward trend line in volume, it is a signal that the mid-term rise may begin, and the middle line can enter the market. Judging trend reversal: When the trend line is broken, there is no longer a new high or low, and the previous fluctuation points are crossed, be alert when two or more of the three signals appear.
