How to Read Stock Charts Without Guessing
Learn price axes, time frames, volume and what candlesticks can and cannot tell you.
- Start with the axes
- Candlesticks summarize completed periods
- Volume and volatility
- Think in scenarios
- Practice
Start with the axes
The horizontal axis usually represents time and the vertical axis represents price. Check whether price displays are adjusted for splits or dividends and which trading sessions are included.
Candlesticks summarize completed periods
Each candlestick shows opening, closing, highest and lowest prices. A single candle does not establish that a price must go in a given direction next.
Volume and volatility
Volume counts trading activity. Large moves can occur on heavy or thin volume and may be affected by news and market liquidity.
Think in scenarios
Instead of saying a pattern predicts a certain outcome, write what evidence would support or contradict your interpretation and how much uncertainty remains.
Practice
Visit the candlestick lesson and explain one rising, one falling and one nearly flat candle using fictional figures.
Put it into practice
Explain the main idea in your own words, identify two risks and find a primary source to validate an important claim. Document what you still don't know.
