Understanding Pattern Day Trading and Its Application to Options

Pattern Day Trading (PDT) rules are designed to protect individual investors from over-leveraging their accounts.

The PDT rule requires a minimum account balance of $25,000 to engage in four or more day trades within a five-trading-day period.

A day trade is defined as a transaction that is closed before the market closes on the same day.

This rule is in place to prevent traders from using excessive leverage, which can lead to significant losses.

In the context of options trading, PDT rules apply to certain types of trades, such as buying and selling options within the same day.

Pattern day trading is a regulatory designation for traders who execute four or more day trades in a margin account over a five-business-day period. This designation is put in place to discourage investors from trading excessively.

To be classified as a pattern day trader, you must execute four or more day trades in a margin account, which constitutes more than 6% of the account's total trade activity during that five-business-day window. This can happen even if you've made only a few day trades in your account.

Suggestion: Business Credit Cards That Don't Report to Personal Credit

The pattern day trading rule only applies if the number of day trades is 6% or more of your total trades during the five business days. For example, if you make four day trades but have 100 total trades in your account, day trading only makes up 4% of your trading activity, and you wouldn't be flagged as a pattern day trader.

If you're flagged as a pattern day trader, your account will be restricted, and you'll be required to maintain a daily equity balance above $25,000 to place opening transactions. If your account's equity balance falls below $25,000.01, trading is restricted to closing transactions only until that account's equity balance is increased to above $25,000.

You can request to have your margin account reclassified as a cash account to avoid the pattern day trading designation. However, this will require your account to be able to withstand the 100% margin requirement of a cash account.

Here are the key differences between a pattern day trader and a non-day trader:

Keep in mind that your brokerage firm is also required to flag your account as a pattern day trader if they have a reasonable belief that you will day trade. This can be based on your previous trading history with the same broker.

A day trade is essentially buying an asset, immediately selling it, and then purchasing the same security again inside the same trading day. This practice is also known as day trading.

The Financial Industry Regulatory Authority, or FINRA, defines day trading specifically as buying and selling the same security on the same day in a margin account. This is why FINRA doesn’t consider you to be a “pattern day trader” unless you execute four or more round-trip trades within five business days.

A round-trip trade can be either buying a security and then selling it, or selling a security and then buying it. To break it down, here's a simple example:

For instance, if you make four day trades but have 100 total trades in your account, day trading only makes up 4% of your trading activity, and you wouldn’t be flagged as a pattern day trader.

A Pattern Day Trader is someone who executes four or more day trades in a margin account over a five-business-day period. This designation is a regulatory classification, not a personal trait.

To be considered a Pattern Day Trader, you must be trading in a margin account, not a cash account. Margin accounts allow you to borrow money from your broker to trade, whereas cash accounts require you to pay for trades upfront.
