Technical Analysis
The study of price, volume, and market behavior using charts and indicators.
Many day traders use technical analysis to structure entries, exits, and risk, but no indicator can reliably predict every price move.
Day Trading Basics
Master the fundamental concepts that every day trader must understand before entering the markets. These basics form the foundation of all successful trading strategies.
What You Need to Know First
Day trading is not just about buying low and selling high. It requires understanding market mechanics, technical analysis, risk management, and trading psychology. Before you can develop a profitable strategy, you must master these fundamentals.

Core Concepts to Master
Volatility
The degree and speed of price movement in a security.
Volatility can create opportunity, but it also increases slippage, stop-outs, and the size of potential losses.
Risk Management
Rules designed to limit losses and protect trading capital.
Position sizing, predefined exits, maximum-loss limits, and avoiding excessive leverage are foundational risk controls.
Market Hours
U.S. stock exchanges have a regular session from 9:30 a.m. to 4:00 p.m. Eastern Time on normal trading days.
Volume and volatility often change throughout the session, and pre-market or after-hours trading has different liquidity and risk characteristics.
Liquidity
The ability to buy or sell without causing a large change in price.
Liquid markets generally make it easier to enter and exit near the prices you expect; thin markets can produce wider spreads and more slippage.
Position Sizing
Choosing the number of shares or contracts based on account size, entry, stop level, and acceptable loss.
Good position sizing starts with the amount you are willing to lose if the trade is wrong—not with the amount you hope to make.
U.S. Day-Trading Margin Rules Changed in 2026
FINRA's replacement intraday margin standards became effective June 4, 2026. The new framework eliminates the old automatic Pattern Day Trader designation and its $25,000 minimum-equity requirement for firms that have transitioned to the new standards.
Important transition: brokerage firms may continue using the legacy day-trading margin provisions while they transition, through October 20, 2027. Your actual requirements therefore depend on your broker and account type.
Check your broker's current rules before trading on margin. See FINRA's current intraday margin guidance.
