A stock chart is a record of prices people already paid. Learn to read it accurately, and learn exactly where its usefulness ends.

Every stock page has a chart, and most beginners look at it first. This topic teaches you to read one the way you would read a table of numbers: carefully, in a fixed order, and without guessing at what it means for the future.

Start with how to read a stock chart. It covers the price and time axes, the three main chart types, why the time window and the price scale can change the story, and how a stock split can look like a crash. Then learn what sits inside each period with candlestick charts, which pack the open, high, low and close into one shape [2].
Moving averages explained works through a simple moving average day by day and shows why the 50-day and 200-day lines always lag the price. Support and resistance explains the price levels traders draw on charts and what they are not. Technical indicators and ratings explains the "Strong Buy" or "Sell" summaries some quote sites show next to a chart, and why they are not advice.
Short definitions live in the glossary: bull market, bear market and market correction. If you size trades with a stop price, the position size calculator works out how many shares fit the amount you plan to risk.
Worked examples use hypothetical stocks calculated in code, never live prices or trading signals, and definitions and rules link to primary sources such as the SEC, FINRA and CME Group.
