What exactly triggers pattern day trader (PDT) status?

In the United States, a common rule is that a margin account making four or more day trades (round trips) in a rolling five-business-day period may be flagged as a pattern day trader, especially if those trades represent more than a small percentage of the account’s activity. However, implementation can vary by broker, and some firms may be stricter or use additional criteria.

Does PDT apply to cash accounts or only margin accounts?

PDT rules are generally applied to margin accounts. Cash accounts are not typically designated as pattern day trader accounts, but they are limited by settlement rules, which means you can only trade with fully settled funds. If you trade too frequently in a cash account, you can still run into good-faith violations or other settlement-related issues.

Do options trades count toward the PDT day trade count?

Yes, in most cases opening and closing an options position the same day is counted as a day trade, similar to stocks. Multi-leg strategies, partial closes, and complex option trades can make the counting more complicated, so consult your broker’s documentation or PDT counter for how they treat those trades.

How strictly is the $25,000 equity rule enforced?

Brokers are generally required to enforce minimum equity requirements for pattern day traders, but the exact timing and mechanics can vary. Some may require the equity to be at or above $25,000 at the start of the trading day, while others may also respond to intraday drops. This calculator simply checks whether your entered equity is above or below $25,000 and does not model intraday changes.

Is the buying power shown here guaranteed by my broker?

No. The buying power figure is an estimate based on simple 4× and 2× multipliers. Your actual buying power depends on your broker’s margin policies, risk models, the specific securities you trade, account history, and regulatory considerations. Always rely on the buying power figure displayed inside your brokerage platform as the authoritative limit.

What should I do if I am close to triggering PDT but do not want that status?

If you want to avoid PDT, you can reduce intraday round-trip trades, hold positions overnight instead of closing them the same day, move some activity to a cash account, or consolidate trades to fewer, higher-conviction setups. The goal is to stay under the four-day-trade threshold over any rolling five-day period in your margin account.

Is this tool financial or regulatory advice?

No. This is a simplified educational and planning tool. It does not account for all aspects of FINRA or SEC rules, nor your broker’s specific policies. For definitive guidance, review your broker’s PDT disclosures, margin agreement, and regulatory notices, and consult a qualified financial professional if you have questions.

Pattern Day Trader (PDT) Checker

Check if your day trades trigger PDT status and show margin buying power.

Results

Triggers PDT: 1.00
Meets $25k rule: 1.00
Estimated buying power: $100,000 USD

Overview

If you actively buy and sell stocks or options in the same day, you have to pay attention to the U.S. pattern day trader (PDT) rules. Make too many round-trip day trades in a margin account without at least $25,000 in equity and your broker can flag you, restrict your trading, or limit your buying power. This PDT checker helps you quickly see whether your recent activity is likely to trigger PDT status and what kind of margin buying power you might have based on your account equity. It is a simplified planning tool, not a substitute for your broker’s official PDT calculations or risk controls.

How to use this calculator

Count your day trades over the last five business days. Each day trade is a buy and sell (or sell and buy to open/close a short) of the same security on the same day.
Enter that count into the "Day trades in 5 days" field. When in doubt, many brokers show your day trade count in the account activity or profile section.
Enter your current account equity from your brokerage dashboard, including any open positions, in the "Account equity" field.
Review whether the calculator indicates that you are at or above the 4 day trade threshold and whether your equity meets or falls short of the $25,000 guideline.
Look at the estimated buying power to get a rough sense of how much you might be able to deploy intraday under typical margin rules.
Use this information to slow down, adjust your trade frequency, or move to a different account type if you are close to triggering restrictions.

Inputs explained

Day trades in 5 days: The number of round-trip day trades you have made in a rolling five-business-day period. A round trip is opening and closing the same position (or closing and reopening in the case of shorts) in the same security on the same trading day. Many brokers display this count for you; if they do, use their figure.
Account equity: Your total account equity, including both cash and the market value of your securities, options, and other positions. The PDT rule typically looks at this equity value at the start of the trading day. If your equity drops below $25,000, you may lose full pattern day trading privileges in a margin account.

Outputs explained

Triggers PDT: A yes/no style indicator showing whether, under the simplified rules used here, your day trade count is at or above the common PDT threshold of four day trades in five business days. Remember that actual broker implementations may count trades differently or flag your account based on their internal logic.
Meets $25k rule: An indicator of whether your entered account equity meets or exceeds the $25,000 guideline typically associated with unrestricted pattern day trading in U.S. margin accounts. Falling below this amount may lead to reduced day-trading flexibility or additional restrictions.
Estimated buying power: A rough estimate of your intraday buying power based on a simple multiplier: up to 4× your equity if you are at or above $25,000 and up to 2× if you are below that level. Real margin limits are set by your broker and may be lower depending on risk controls, specific securities, or regulatory requirements.

How it works

You enter the number of day trades (round trips: opening and closing the same position in the same security on the same day) you have made in a rolling 5-business-day period.

You also enter your current account equity, which is the total value of cash and securities in your account, including unrealized gains and losses, as typically reported by your broker.

The calculator checks whether your day trade count is at or above the commonly used PDT threshold of four day trades in five business days in a margin account.

It then compares your account equity to the $25,000 guideline for unrestricted pattern day trading. Accounts at or above this level are generally allowed higher intraday margin buying power, subject to broker rules.

For buying power, the tool uses a simple rule-of-thumb: if your equity is at least $25,000, we estimate up to 4× intraday buying power; if your equity is below $25,000, we estimate a more conservative 2× buying power similar to many non-PDT margin or cash-style constraints.

The result is a quick snapshot: whether your recent trading pattern might be considered PDT-like and an approximate maximum buying power figure. Always verify the real values in your brokerage platform, which may apply additional risk or exposure limits.

Formula

PDT trigger (simplified) = dayTradesInFiveDays ≥ 4\nMeets equity rule = accountEquity ≥ $25,000\nEstimated buying power = accountEquity × (4 if meets equity rule else 2)

When to use it

Checking whether your recent trading activity is approaching or exceeding the typical PDT trade count threshold.
Planning how many day trades you can make in the next few sessions without crossing the line into pattern day trader status in a margin account.
Estimating how much buying power you might have if you increase your account equity to at least $25,000.
Comparing how different equity levels (for example, $10,000 vs. $30,000) change your potential buying power and day-trade flexibility.
Exploring whether a cash account, lower-frequency swing trading, or adding funds might better match your desired trading style under PDT rules.

Tips & cautions

If you are below the $25,000 equity level and want to avoid PDT flags, track your rolling five-day day trade count closely and stay under four day trades during that period.
Remember that pattern day trader rules generally apply to margin accounts. Cash accounts can avoid PDT designations but are constrained by T+2 or T+1 settlement, which can limit how often you can recycle capital.
Keep in mind that opening and closing options positions intraday can count as day trades, not just stock trades. Check your broker’s documentation for exactly what they consider a day trade.
Do not assume that your broker will always let you use the maximum theoretical buying power. They may impose stricter limits based on your experience, account history, or specific securities.
If you are close to triggering PDT status unintentionally, consider changing your strategy to longer holding periods (swing trades) or reducing the number of intraday round trips.
Always double-check your broker’s PDT status and buying power display on trading days. This calculator is meant for planning, not real-time risk management.
This tool uses a simplified definition of day trades and a basic 4×/2× buying power assumption. Actual broker implementations of PDT and margin rules can be more nuanced and may vary across firms.
It does not account for intraday equity fluctuations, unsettled funds, maintenance margin requirements, concentration limits, or house-specific risk controls.
The rolling five-business-day count can be tricky to compute manually, especially if you trade actively. When possible, rely on the day trade counter displayed by your broker as the authoritative source.
The calculator does not differentiate among asset classes (stocks vs. options vs. leveraged ETFs), even though these can carry different margin requirements and risks.
Nothing here guarantees that you will or will not be designated as a pattern day trader. Only your broker can apply that status according to regulatory and internal policies.

Worked examples

4 day trades in 5 days, $27,000 equity

Day trade count = 4, which meets the common PDT threshold in a margin account.
Account equity = $27,000, which is above the $25,000 guideline.
PDT trigger (simplified) = yes, but equity also meets the $25,000 rule, so the account is positioned for pattern day trading under typical rules.
Estimated buying power ≈ $27,000 × 4 = $108,000 in intraday margin buying power (subject to broker limits).

2 day trades in 5 days, $18,000 equity

Day trade count = 2, which is below the four-trade PDT threshold.
Account equity = $18,000, below the $25,000 guideline.
PDT trigger (simplified) = no; you are under both the trade count threshold and the equity requirement for full PDT-style margin.
Estimated buying power ≈ $18,000 × 2 = $36,000, assuming a 2× margin-style limit for smaller accounts.

6 day trades in 5 days, $20,000 equity

Day trade count = 6, which is well above the typical four-trade PDT threshold.
Account equity = $20,000, which is below the $25,000 guideline.
PDT trigger (simplified) = yes, and you do not meet the equity rule; your broker may restrict or freeze further day trading in this margin account.
Estimated buying power ≈ $20,000 × 2 = $40,000, but in practice your broker may drastically reduce or remove margin buying power when PDT restrictions are applied.

Deep dive

This pattern day trader (PDT) checker helps active traders quickly estimate whether their recent day trades might trigger PDT status and how much intraday buying power they might have at different equity levels. By entering your day trade count over the last five business days and your current account equity, you get an at-a-glance view of how close you may be to the common four-day-trade threshold and whether you meet the widely known $25,000 equity guideline.

Use the calculator when you are planning to become more active with your day trading strategy and want to understand how account size, PDT status, and margin buying power interact. It can be particularly helpful if you are deciding whether to add funds to reach the $25,000 mark, stay below it and trade less frequently, or move to a cash account or longer-term approach that avoids many PDT restrictions. While the tool simplifies complex brokerage rules, it is a practical starting point for thinking about risk, leverage, and regulatory limits before you scale up your trading activity.
