Pattern day trading (PDT) is a regulatory term used in U.S. stock markets to classify traders who execute four or more day trades within five business days in a margin account, provided the number of day trades represents more than 6% of the total trades in that account. Understanding PDT rules, strategies, and risk management is essential for active traders to avoid regulatory issues and maximize short-term trading opportunities. This article explores the definition, requirements, strategies, tools, and risk management practices associated with pattern day trading.
Understanding Pattern Day Trading
A day trade is defined as the purchase and sale (or sale and purchase) of the same security on the same trading day. Pattern day traders are subject to specific rules by the Financial Industry Regulatory Authority (FINRA) in the United States:
- Minimum Equity Requirement: A pattern day trader must maintain at least $25,000 in their margin account at all times.
- Day Trade Count: Executing four or more day trades within five business days triggers PDT classification if trades exceed 6% of total activity.
- Margin Account Requirement: PDT rules apply only to margin accounts, not cash accounts.
Advantages:
- Ability to leverage margin for increased buying power.
- Access to advanced trading strategies including scalping, momentum, and swing trading intraday.
- Opportunities to capture short-term price movements in volatile markets.
Challenges:
- Risk of rapid losses due to leverage.
- Regulatory penalties for violating PDT rules.
- Requires active monitoring and disciplined trading approach.

Common Pattern Day Trading Strategies
1. Momentum Trading
Captures stocks moving strongly in one direction, often due to news, earnings, or volume spikes.
Example:
- Buy 100 shares at $50 → sell at $53
- Profit: \text{Profit} = (53 - 50) \times 100 = 300
2. Scalping
Targets small, frequent price movements within minutes.
Example:
- Buy 100 shares at $50 → sell at $50.10
- Profit: \text{Profit} = (50.10 - 50.00) \times 100 = 10
3. Breakout Trading
Enter trades when a stock breaks above resistance or below support.
Example:
- Resistance at $60 → price breaks to $61, buy 50 shares → target $65
- Profit: \text{Profit} = (65 - 61) \times 50 = 200
4. Reversal Trading
Trade against short-term extremes indicated by indicators or candlestick patterns.
Example:
- RSI < 30 → buy 100 shares at $48 → sell at $52
- Profit: \text{Profit} = (52 - 48) \times 100 = 400
Risk Management in Pattern Day Trading
| Risk Control | Description | Example |
|---|---|---|
| Position Sizing | Limit exposure per trade | Risk 1–2% of capital per trade |
| Stop-Loss Orders | Automatically exit losing trades | Stop-loss at $48 for $50 entry |
| Take-Profit Orders | Lock in gains at target levels | Exit at prior swing high |
| Daily Loss Limit | Stop trading if daily losses exceed threshold | Stop trading for the day if losing $500 |
| Margin Monitoring | Ensure account stays above $25,000 requirement | Maintain equity to avoid forced account restrictions |
