Day trading opens and closes positions within the same trading day, usually to trade short-term price movement.
Day trading opens and closes positions within the same trading day. A day trader may trade stocks, options, futures, currencies, ETFs, or other instruments, but the defining feature is the same-session holding period rather than the asset class.
Day trading is high risk because decisions are compressed into short time windows. Costs, spreads, leverage, emotional pressure, platform outages, and fast price changes can overwhelm a strategy. This page is educational only and is not trading or investment advice.
| Style | What it tries to capture | Main risk |
|---|---|---|
| Momentum | Continuation of a strong short-term move | Reversal, crowding, late entry |
| Breakout | Move beyond a price range or level | False breakout and slippage |
| Scalping | Very small price changes over many trades | Costs, spread, speed, overtrading |
| News reaction | Fast adjustment to earnings, economic data, or headlines | Bad data, delayed execution, volatility shock |
| Mean reversion | Snapback after an intraday extreme | Trend keeps moving against the position |
A trader buys a liquid ETF after a strong opening move and plans to exit before the market closes. The trade plan should specify the entry trigger, order type, maximum position size, loss limit, target or exit rule, and what happens if the ETF gaps through the stop.
Without those details, “day trading” is only a label. It does not say whether the trade has a defined edge or acceptable risk.
| Style | Holding period | Main difference |
|---|---|---|
| Intraday Trading | Same session | Broad same-day activity, often used interchangeably with day trading |
| Swing Trading | Days to weeks | Accepts overnight and weekend risk |
| Position Trader | Weeks to months or longer | Relies more on sustained trends or fundamental thesis |
| Long-term investing | Years | Focuses on ownership, cash flows, and compounding rather than same-day execution |
FINRA’s day trading page explains day trading in margin accounts and links to pattern day trader requirements. FINRA Rule 2270 provides the Day-Trading Risk Disclosure Statement, which warns about substantial losses, commissions, margin, short selling, and system failures. SEC Investor.gov’s day trading risk page is another useful investor-risk source.
