Charts help investors identify major market trends such as uptrends, downtrends, or sideways movements. Understanding the trend allows investors to choose appropriate strategies. -
Determining entry and exit points:

By interpreting charts, investors can set stop-loss levels and profit targets more effectively, improving risk management. -

Charts provide visual, immediate information, helping investors grasp market conditions quickly and make timely decisions. -
Supporting investment strategy development:
Chart data enables investors to build and adjust their investment strategies more flexibly and effectively.
III. How to read and analyze stock charts
1. Trading volume
Trading volume indicates the market’s level of interest in a stock. Changes in volume can signal upcoming price movements.
-
High volume with strong upward or downward trends confirms the strength of that trend.
-
Low volume may indicate low market interest, making the stock less attractive.
Common interpretations:
-
High volume + rising price → price may continue to rise
-
Low volume + falling price → price may rebound
-
High volume + falling price → price may continue to decline
-
Low volume + rising price → price may fall again due to weak confidence
2. Technical indicators
Indicators like RSI, MACD, Bollinger Bands provide additional insights into the strength and momentum of price trends.
There are two main indicator types:
-
Trend indicators — show overall price direction (e.g., Moving Averages – MA).
-
Momentum indicators — measure price volatility to find good entry points (e.g., MACD, RSI).
3. Identifying trends
-
Uptrend: Price consistently rises, forming higher highs and higher lows.
-
Downtrend: Price consistently falls, forming lower highs and lower lows.
-
Sideways trend: Price moves within a narrow range with no clear direction.
4. Timeframes
Investors choose timeframes based on their strategy:
-
Short-term: minutes (5m, 15m, 30m)
-
Medium-term: hours or days (1H, 4H, 1D)
-
Long-term: weeks, months, years (1W, 1M, 1Y)
