How to use trend lines

Trend line is a curve made by investors according to the historical highs or lows of individual stocks, which is used to predict the future trend of individual stocks. Investors can use the trend line to find trading opportunities for individual stocks.

For example, the trend line made according to the historical highs of individual stocks can be regarded as the recent pressure position of individual stocks. Whenever the stock price rises beyond this curve, it is an opportunity to sell. If the stock price rises and breaks through this trend line, then individual stocks may continue to rise and hit a new high, which is a buying opportunity; According to the historical lows of individual stocks, the trend line can be regarded as the recent support level of individual stocks. Every time the stock price falls and touches the curve rebound, it is a buying opportunity. If the stock price falls below the trend line, individual stocks may continue to fall and hit a new low, which is a signal to sell. If a stock fluctuates back and forth between the downtrend line and the uptrend line, investors can use its trend to make short-term high selling and low sucking operations.
