Recently, while studying technical analysis, I found that many people actually have misconceptions about this set of tools. To be honest, technical analysis is often criticized as "storytelling with charts," but the problem isn't with the tools themselves; it's whether the user truly understands the underlying logic.

Simply put, technical analysis involves judging market direction through price movements. When prices continuously rise or fall, we call it a "trend"; conversely, when prices fluctuate within a certain range, it's called "consolidation." It's that simple, and can be summarized into three market conditions: bullish, bearish, and sideways.

Many people prefer to trade directly based on price movements. The advantage is flexible entry and exit, allowing quick profits or risk management. But the downside is obvious—when there is no trend, prices tend to fluctuate randomly, causing signals to fail. Therefore, technical traders must overcome issues like overtrading and not following discipline, and continuously backtest and refine strategies to maintain a winning rate.

Throughout history, technical analysis masters have created many tools to better identify market conditions. The most common are "pattern recognition," which classifies price charts directly, and "technical indicators," which calculate price and volume through formulas. Technical indicators are divided into trend-following types (like moving averages, MACD) and oscillators (like KD, RSI).

My most frequently used tool is still candlestick charts. This method was first invented by a rice merchant named Honma Munekyu during Japan’s Edo period, to record rice market prices. Candlesticks consist of four values: "Open," "Close," "High," and "Low," represented by a small line segment that visually records a day's price movement. When buying pressure is strong, the candlestick is red; when selling pressure dominates, it’s green. The color quickly conveys the market’s bullish or bearish sentiment.

By combining multiple candlesticks, classifying and identifying specific arrangements, you can form "patterns." I find this to be the most practical advanced technical analysis method. Pattern recognition is fundamentally divided into three types: bottom, head, and consolidation zones.

The bottom zone is when the price is relatively low. The most common pattern is the "W bottom." A W bottom looks like a big W, with the left side called the "left leg" and the right side called the "right leg." The formation principle is: after a sharp decline, heavy trading occurs, and selling pressure exhausts itself, forming the first leg; then, a rebound occurs but no new investors enter, causing the price to settle back down and form the second leg; finally, more investors notice the stock, and when the price breaks the neckline (the high point of the left leg rebound), it triggers a surge of capital chasing the stock, volume explodes, and the W bottom is formed. Once confirmed and the neckline is broken, it usually triggers a rally.

Conversely, there's the "M top," which is the inverted version of the W bottom, looking like a big M. The left side is called the "left shoulder," and the right side the "right shoulder." The formation principle is: after a sharp rise, heavy selling occurs at the high point, causing the price to fall and form the left shoulder; after the decline, some investors see it as a pullback and buy in, but the chasing volume isn't enough, and the price can't break previous highs, forming the right shoulder; finally, buying interest weakens, and when the price breaks the neckline, it accelerates downward, forming the M top. At this point, it’s advisable to consider selling quickly and exiting.

Lastly, I want to mention moving averages, a very popular indicator overlaid on candlestick charts. Moving averages represent the average closing price over a certain period, reflecting investors’ cost basis and providing a clear view of the trend. Market analysis tools typically include six lines: 5-day, 10-day, 20-day, 60-day, 120-day, and 240-day. The 5-day and 10-day are short-term averages; 20-day and 60-day are mid-term; 120-day and 240-day are long-term.

The simplest practical approach is to keep only one moving average based on your trading cycle. When the moving average continuously trends upward and the price stays above it, it indicates bullish dominance, and a long bias can be considered; conversely, if the moving average trends downward and the price stays below it, it indicates bearish dominance, and a short bias can be considered. If the price keeps crossing above and below the moving average, it signals sideways consolidation, and trading becomes risky with frequent stop-losses, so it’s better to stay out.

Another common strategy is the moving average crossover. When a short-term moving average crosses above a long-term one, it indicates the price is accelerating upward—called a "golden cross," which can be a buy signal. Conversely, when the short-term moving average crosses below the long-term one, it indicates weakness—called a "death cross," which can be a sell signal.

Honestly, is technical analysis useful? It all depends on whether the user truly understands its logic and is disciplined in following it. The tools themselves are fine; the issue lies in execution.
