How prices, charts, orders and volume work — the ten ideas everything else builds on.

About an hour of reading in total. Finish with the Basic quiz to check what stuck.

1. What Is Volatility and Why Does It Matter for Traders? — Volatility gets blamed for both the biggest gains and the biggest losses in trading. Understanding what it actually measures changes how you size risk.

2. How to Read Candlestick Charts: A Beginner's Visual Guide — Candlestick charts pack four numbers into every bar. Once you know what each part represents, reading price action gets dramatically faster.

4. What Is Market Cap and Why Does It Matter? — Market cap gets thrown around as a size ranking, but it's really a measure of what the market as a whole thinks an asset is worth — and it changes how you should read a price move.

5. What Is Liquidity in Trading? — Two assets can look identical on a price chart and behave completely differently the moment you try to actually trade a meaningful size.

6. Bid Price vs. Ask Price: What Is the Spread? — Every tradable asset technically has two prices at once. The gap between them — the spread — is a hidden cost that's worth understanding before you place an order.

7. Market Order vs. Limit Order: What's the Difference? — The two most basic order types in trading, and choosing the wrong one for the situation is a surprisingly common beginner mistake.

A guide to what index futures are, who trades them overnight, how the percentage on the screen is calculated, and why the number tells you about the open but not about the close.

10. What Is Trading Volume, and Why Does It Matter? — The same price move can mean very different things depending on how much volume came with it.

11. What Are Support and Resistance Levels? — Prices don't move in a straight line — they tend to stall at certain levels over and over. Learning to spot those levels is one of the first real skills in reading a chart.

12. What Is an ETF and How Is It Different From a Stock? — ETFs trade just like individual stocks but represent something different underneath. Here's the distinction that actually matters for a trader.

13. Price-Weighted vs Market-Cap-Weighted Indexes: Why the Dow Fell 1.23% and the S&P 500 Only 0.52% on October 23, 2026 — The Dow Jones Industrial Average weights its 30 stocks by share price, the S&P 500 by company size, and on some days that difference decides the headline.
