Pattern Day Trader
A Pattern Day Trader (PDT) is a US regulatory designation applied to margin account holders who execute four or more day trades within five consecutive business days, requiring a minimum equity of USD 25,000 — a rule with no equivalent in India.
The Pattern Day Trader rule is a creation of the US Financial Industry Regulatory Authority (FINRA) and was codified under NASD Rule 2520. It applies exclusively to margin accounts at US broker-dealers and mandates that any customer classified as a PDT maintain a minimum equity of USD 25,000 at all times. If the account falls below that threshold, the broker restricts the account to closing transactions only until the equity is restored. The rule was introduced in 2001 following regulatory concerns about retail speculation during the dot-com bubble.
India has no corresponding statutory PDT designation. SEBI and the NSE/BSE do not impose a minimum capital threshold for intraday traders, nor do they count the number of intraday round-trips a trader may execute in a given week. An Indian retail investor with a margin-funded account of Rs 10,000 can technically execute unlimited intraday trades in the MIS (Margin Intraday Square-off) product category, subject only to the available intraday leverage and the broker's own risk management system (RMS) limits.
The margin treatment differs substantially between the two regimes. A PDT account in the US is entitled to four times the overnight maintenance margin for intraday purposes — called day-trading buying power. Indian MIS margins, by contrast, were set by individual brokers until SEBI's peak margin circular (effective from September 2021) capped intraday leverage for equity cash to the extent of the SEBI-prescribed VaR plus ELM margin, bringing Indian intraday margin requirements closer to delivery margins and significantly curtailing the 10x to 20x leverage that discount brokers previously offered.
For Indian traders who also trade US markets through platforms offering US equities — such as through the LRS route under the RBI's Liberalised Remittance Scheme — the PDT rule becomes directly relevant. If an Indian resident maintains a US brokerage account funded below USD 25,000, each day-trade counts against the five-trade weekly limit, and triggering the PDT flag can freeze the account's intraday capabilities for 90 days.
The absence of an Indian PDT equivalent does create a freer intraday environment, but SEBI's peak margin norms, the Integrated Risk Management and the broker-level auto square-off mechanisms collectively discipline leverage in a different but functionally comparable way. The comparison illustrates that both jurisdictions have arrived at capital-discipline mechanisms through distinct regulatory philosophies.
