Pattern day trader rule

Plain-language meaning

The U.S. pattern day trader designation is a broker-dealer margin-account rule with eligibility and equity requirements under current regulation.

Why it is useful

Pattern day trader rule is useful as descriptive evidence when it is compared on the same definition, source, period, unit and exact listing. It is one input to research, not a verdict.

Where it appears in XMarketRadar

Look for Pattern day trader rule in United States company intelligence, filings, official-data and exact NASDAQ/NYSE listing research.

How it is calculated or sourced

Pattern day trader rule comes from the named regulator, exchange, filing system, broker record or official publication. XMarketRadar preserves the source identity and date rather than translating absence into a value.

Inputs, period and unit

Read the disclosed inputs or source, observation period, bar interval, unit, native currency and scale. A value without its source and as-of context is incomplete; unlike units must not be combined.

Worked example

Illustrative only: An account making four qualifying day trades inside the applicable five-business-day test can trigger broker review under the current U.S. rule; account type and current regulation still govern.

What high and low mean

A higher or lower Pattern day trader rule value is descriptive, not automatically good or bad. Meaning depends on the instrument, comparison period, method and related evidence.

Positive, negative and genuine zero

Positive and negative Pattern day trader rule values retain the definition shown here. A genuine reported or computed zero is displayed as 0 and is not the same as missing evidence.

When it is unavailable

Unavailable (—) means Pattern day trader rule is absent, unsupported, stale under the screen's rules or not computable from verified inputs. It must never be converted to zero or a neutral signal.

Limitations and common mistakes

Rules and filing timetables can change. Pattern day trader rule should be checked against the linked official source; a glossary summary is not legal, tax or regulatory advice.

Market-specific differences
