A picture is worth a thousand words and stock charts are no different. Full of lines, colours and some unique patterns, they can look intimidating to a beginner. But once you get the basics, they can help you towards appropriate decision making. If you have ever wondered how seasoned stock market investors make quick buying and selling decisions, the answer is, most of them can read stock charts efficiently.
A stock chart is a picture, a graphical depiction that shows how a stock's price has moved over time. The chart helps you see if a stock is going up, going down or staying flat. When you apply science to them, they are visual representations of market psychology, trends and opportunities. While fundamental analysis focuses on a company’s financial health, technical analysis, which is enabled by stock charts, examines price action and market behaviours.
Before understanding charts and their types, lets get to know their basic components,
Or Y axis. Located on the right side, it shows the stock’s price levels.
Or X axis. Runs along the bottom, representing the time frame. Can be minutes, days, weeks or months.
Usually displayed below the price chart, volume shows how many shares were traded during a specific period.
These lines connect price points to show the overall direction, uptrend, downtrend or sideways.
To begin with, let’s look at the most common chart types
The simplest form, showing the closing price over a period. It is good for beginners. However, it lacks detailed information like highs, lows and volume.
Displays opening, closing, high and low prices for each time period
The most popular among traders. Each ‘candle’ shows the open, high, low and close prices, with colours indicating bullish (price up) or bearish (price down) movements.
Since candlesticks are most commonly used, let's understand them better.Each candlestick represents a specific time period, be it, minute, hour or day The rectangular part is called the ‘body’ and the lines sticking out are called ‘wicks’ or ‘shadows’.
Green (or White) candles Indicates the stock went up. The bottom of the body shows the opening price and the top shows the closing price.
Red (or Black) candles Indicates the stock went down. The top shows the opening price and the bottom shows the closing price.
The wicks show the highest and lowest prices reached during that period. For example, a green candle with a long top wick means the stock reached higher but fell back before closing still up for the day, just not at the highest point it reached.
Patterns are the language of charts. Here are a few basics,
means higher highs and higher lows. This indicates bullish sentiment.
means lower highs and lower lows. Signals bearish sentiment.
As you look at charts, you will notice that stocks often bounce off certain price levels.
Support This is a price level where the stock usually stops going down and bounce back up. It's like a floor. Buyers think the stock is a good deal at this price, as its floor level prices are expected to go up from here.
Resistance This is a price level where the stock usually stops rising and falls back down. It's like a ceiling. So when stock price reaches its ceiling, sellers tend to sell anticipating decline in stock prices after it has reached ceiling.
These levels are important because they help you predict where a stock might change direction.
Most charts show volume at the bottom, usually as vertical bars. Volume tells you how many shares were traded during each period. High volume means lots of people are buying and selling.
This usually happens when important news comes out or when a stock makes a big move. High volume indicates high interest, which means a trend is strong.
Low volume means not many people are trading. Moves on low volume might not last because there is not much conviction behind them.
A stock might be in an uptrend when you look at a one-year chart but in a downtrend on a one-month chart. Hence, time frame matters. Short-term traders look at minutes, hours or days. Long-term investors look at months or years. Choose the time frame that matches your investing time frame.
Stock charts are not crystal balls, they cannot predict the future perfectly. But they do show you what has been happening and help you spot patterns. The more you practice reading charts, the more natural it becomes.
