I remember feeling overwhelmed when I first looked at a chart. Candles that look like little flames densely packed together, with lines of various colors tangled above them. But it's simpler than it seems. These tools are ultimately just to help read the stock's movements more clearly.

Let's start with candlestick charts. Green candles indicate days when the price went up, red candles show days when it went down. The thick body of each candle shows the opening and closing prices, and the thin lines (wicks) extending above and below represent the highest and lowest prices of the day. The longer the body, the greater the price fluctuation on that day. Especially, if a long candle suddenly appears, it signals that something significant has happened, so you should watch carefully.

Now, this is an important part: support and resistance lines. Have you ever seen a stock bounce back repeatedly at a certain price level? Those points are connected to form support lines. Conversely, if the price keeps falling back when it approaches a certain level without breaking through, that forms a resistance line. Resistance lines are often used as sell signals because when the price hits resistance, it’s likely to fall. However, if the price breaks through a resistance line and goes higher, that line can become a new support level. This concept is really important.

Next is the moving average line. The "moving average" you often hear about in news is exactly this—an average of the stock price over a certain period, plotted as a line. Common ones are the 5-day, 20-day, and 60-day moving averages. By looking at how these lines are arranged, you can identify the trend. If the short-term moving average is above the long-term one, it’s an uptrend (called a bullish alignment); if below, it’s a downtrend (called a bearish alignment). The most practical way to use this is to spot golden crosses and death crosses. When the short-term line crosses above the long-term line, it’s a buy signal (golden cross). When it crosses below, it’s a sell signal (death cross).

Finally, the OBV indicator. Also called the On-Balance Volume indicator, it’s based on the principle that volume precedes price movement. It adds volume on days when the price rises and subtracts volume on days when it falls. If the price is rising but OBV isn’t changing much, that’s a sign that buying momentum is weakening. Without volume supporting the move, it’s hard for the upward trend to continue.

The key point is that you shouldn’t rely on these tools alone. Support and resistance lines or moving averages alone are not enough. Combining multiple indicators gives a more accurate picture. It might seem complicated at first, but as you look at charts more often, it will become natural to read them. These basics will serve as a foundation for smarter investment decisions.
