Frequent Intraday Trading and the Former PDT Rule

For educational purposes only; not investment advice.

Direct answer

Section titled “Direct answer”

FINRA’s current investor guidance focuses on intraday margin requirements, not the former uniform pattern day trader (PDT) counting test. A broker monitors positions held during the trading day and compares required margin with account equity. If equity is insufficient, the account has an intraday margin deficit that the firm expects to be satisfied promptly.

Older explanations often say that four or more day trades within five business days, subject to a 6% test, triggered a PDT designation and a $25,000 minimum-equity requirement. Those thresholds describe the former framework and should not be used as a current operating rule. Account screens, broker policies, and older educational material can lag, so customers should verify the rules actually applied by their firm.

How current intraday margin works

Section titled “How current intraday margin works”

A same-day purchase and sale can create exposure during the session even if no position remains at the close. Current intraday margin calculations look at positions during the day rather than only end-of-day holdings. The broker monitors whether account equity adequately supports those positions under applicable regulatory and house requirements.

FINRA’s current guidance states that using borrowed funds requires at least $2,000 of margin-account equity, while a broker may require more. This general minimum is not a promise of sufficient intraday buying power: riskier, larger, concentrated, or volatile positions can require substantially more equity.

If a deficit occurs, the firm may expect a deposit or position liquidation as promptly as possible. A repeated practice of creating intraday deficits and not promptly satisfying them can require the firm to freeze margin trading for 90 days or until the deficit is satisfied, whichever comes first. Broker agreements may also permit earlier restrictions or liquidation.

Cash accounts do not use margin loans, but they are not a universal workaround. They remain subject to full-payment, settlement, good-faith, and freeriding rules. The account type changes which rules apply; it does not make repeated trading consequence-free.

Intraday deficit example

Section titled “Intraday deficit example”

Suppose a broker’s intraday calculation requires $18,000 of equity for positions accumulated during the session, but the account has $14,000 of eligible equity.

Intraday margin deficit = $18,000 - $14,000 = $4,000

Closing the positions before the market close does not erase the fact that the exposure existed. The firm determines how the deficit must be satisfied and whether restrictions apply under its rules.

Contrast that with the former PDT counting example: four qualifying day trades in five business days could have triggered the old designation when its percentage test was met. Under current guidance, memorizing that count does not determine the margin required for the actual intraday positions.

Risks and operational checks

Section titled “Risks and operational checks”
  • Buying-power changes: displayed capacity can fall as positions, volatility, or house requirements change.
  • Deficit restrictions: unresolved or repeated deficits can limit margin activity.
  • Forced sales: a broker can liquidate positions under the margin agreement.
  • Execution risk: frequent orders compound spread, slippage, fees, and market impact.
  • Settlement violations: cash-account trading can still breach payment and settlement rules.
  • Legacy terminology: an interface may still display PDT labels or counters that do not fully explain current calculations.
  • Options complexity: opening and closing options on the same day can create exposure whose treatment depends on position and firm rules.

Before trading, confirm the account type, current equity, intraday buying power, security-specific requirements, deficit cure procedure, and whether the broker has placed any restrictions on the account.

Common misconceptions

Section titled “Common misconceptions”

“Everyone may now day trade without limits.” Intraday margin, broker risk controls, and cash-account settlement rules still apply.

“Keeping more than $2,000 guarantees sufficient buying power.” It meets a general margin-account minimum cited by FINRA, not the requirement for every position.

“Closing before the bell eliminates margin consequences.” Intraday calculations examine exposure held during the session.

“A cash account has no trading restrictions.” Full-payment and settlement violations can still lead to limits.

“The old $25,000 number remains the universal current threshold.” It belongs to the former PDT framework; verify current firm calculations instead.
