The pattern day trader rule is a regulatory framework designed to protect investors and prevent excessive trading activities that could be financially detrimental. Here are the key aspects of the pattern day trader rule:
- Definition: A pattern day trader is defined as any customer who executes four or more day trades within five business days, provided that the number of day trades represents more than 6% of the customer’s total trades in the margin account for that same five business day period12.
- Minimum Equity Requirement: Pattern day traders must maintain a minimum equity of $25,000 in their margin account at all times. If the account falls below this threshold, the trader may be restricted from day trading until the account is restored to the required minimum equity level12.
- Day Trading Margin Limit: Pattern day traders are limited to a maximum of three day trades in a five-business-day period if their account equity is below $25,000. This is to reduce the risk of excessive trading and financial losses12.
- Day Trade Buying Power: The day trade buying power is determined by the maintenance margin excess as of the close of business of the prior day. This power represents the amount of marginable stock that can be day traded without incurring a day trade margin call2.
- Day Trade Margin Calls: If a pattern day trader exceeds the day-trading buying power limitation, a day-trading margin call is issued. The trader has five business days to deposit funds to meet the call; failure to do so may result in further restrictions on trading12.
- Pattern Day Trader Designation: Brokers may designate customers as pattern day traders based on their trading activities, training history, or other reasonable basis. Once designated, the trader must adhere to the pattern day trader rules until the designation is removed3.
The pattern day trader rule is intended to safeguard investors by limiting their day trading activities and ensuring they maintain a sufficient equity balance to support their trading activities.
