Many beginners, when analyzing technical charts, always think that the more complex indicators are the most powerful. But in reality, the simplest tools are often the most effective—trend lines, channel lines, and moving averages are such tools. They look simple, but behind them hides the entire market's pulse.

In plain terms, these three tools are drawing the "skeleton" of the market for you. Price movements in the market are not random; they always fluctuate rhythmically along a certain direction. Once you understand this rhythm, you can identify key support and resistance levels.

First, let's talk about trend lines. During an uptrend, connect the successive higher lows; this line tells you where the buyers are saying "no more decline." Conversely, in a downtrend, connect a series of lower highs; this line clearly indicates the sellers' pressure. This line itself will automatically turn into support or resistance levels, where many large orders determine the outcome.

But trend lines alone are not enough. Channel lines come in to complete the picture—during an uptrend, find the first obvious high point, and draw a line parallel to the trend line; this is the upper boundary of the ascending channel. Price oscillates within this channel; the lower boundary is where you should consider bottom-fishing, and the upper boundary is where you might think about selling or reducing positions. The width of the channel can also help estimate future price targets. When the price breaks above the channel's upper boundary, it often signals the start of a new wave of market movement.

When these tools are used well, you are not blindly chasing highs or selling lows, but truly "reading the road." The market always moves according to its rhythm; the key is whether you can see it clearly.
