Pattern Day Trader (PDT): Definition, Rules, and Functionality

Understand what a Pattern Day Trader (PDT) is, the rules governing PDT status, and how it affects trading strategies and regulations.

A Pattern Day Trader (PDT) is a regulatory term for traders or investors who execute four or more day trades within a five-business-day period in a margin account. This designation comes with specific rules and requirements imposed by financial regulatory bodies to mitigate the risk associated with frequent trading.

Definition of a Pattern Day Trader (PDT)

The Financial Industry Regulatory Authority (FINRA) defines a Pattern Day Trader as anyone who fulfills the following criteria within a five-business-day period:

  • Executes four or more day trades.
  • Trades are carried out in a margin account.
  • The number of day trades represents more than 6% of the customer’s total trading activity in that same period.

Rules Governing Pattern Day Trading

There are several critical rules and requirements to be aware of when it comes to Pattern Day Trading:

Minimum Equity Requirement

Under FINRA regulations, a Pattern Day Trader must maintain a minimum equity of $25,000 in their margin account on any day that day trading occurs. This equity can be a combination of cash and eligible securities.

Day Trading Buying Power

Pattern Day Traders are allowed up to four times the maintenance margin excess as of the close of the previous day. This is known as “day trading buying power.” Any trading that exceeds this limit prompts a margin call, which must be met within five business days. Failure to meet the margin call results in a restriction on day trading.

Restrictions and Penalties

If a trader is flagged as a Pattern Day Trader and falls below the $25,000 equity requirement, the account will be restricted to trading only on a cash-available basis for 90 days or until the minimum equity is restored.

Special Considerations for Pattern Day Traders

Risk Factors

Day trading is inherently risky due to the rapid and frequent buy-sell decisions. Therefore, regulators impose stringent requirements to ensure that only individuals with the financial capability (i.e., the required equity) engage in this type of trading.

Margin Calls

Failure to meet a margin call can lead to forced liquidation of positions by the broker, which may result in significant financial loss.

Alternative Strategies

Traders unable to meet the PDT requirements might consider alternative strategies, such as swing trading or investing, which do not require the same level of frequent trading and are not subject to the PDT rules.

Historical Context and Applicability

The PDT rule was established after the dot-com bubble burst in the early 2000s to promote financial stability and protect retail investors from the high risks associated with day trading. The rule ensures that those who engage in frequent trading maintain a significant account balance, thereby providing a buffer against potential losses.

  • Margin Account: An account offered by brokers that allows investors to borrow money to buy securities, subject to certain regulations and interest rates.
  • Swing Trading: A trading strategy that involves holding positions for a period of several days to weeks, to capitalize on expected price swings.
  • Maintenance Margin: The minimum amount of equity that must be maintained in a margin account.

FAQs

What happens if my account falls below the $25,000 minimum equity requirement?

If your account’s equity falls below $25,000, you will be restricted to trading only on a cash-available basis for 90 days, or until the minimum equity is restored.

Can I day trade with a cash account?

No, day trading typically requires a margin account because of the leverage involved. Cash accounts are subject to different rules and do not allow the same level of frequent trading.

How can I avoid being flagged as a PDT?

To avoid being flagged as a Pattern Day Trader, you can reduce the number of day trades you execute to fewer than four trades within five business days or ensure that these trades do not represent more than 6% of your total trading activity in that period.
