Stock-market trading is buying and selling securities — stocks, ETFs and more — to take part in companies' growth and manage capital over time. This guide explains how the market works, the trading styles, and how to make data-driven decisions.

Day trading means opening and closing positions within the same session, holding nothing overnight. It's the most demanding style — it needs screen time, iron discipline and tight risk control.

Technical analysis forecasts likely price moves from price and volume history rather than fundamentals. The assumption: information is already in the chart and patterns tend to repeat. This guide covers the building blocks every trader should know.

Swing trading captures medium moves over days to weeks — a middle ground between day trading and long-term investing, needing far less screen time while still leaning on technical analysis.
