# What replaced the $25,000 pattern day trader rule

FINRA replaced the PDT rule with intraday margin from 4 June 2026, but firms may phase in until 20 October 2027, and cash accounts were never under it.

**Answer:** FINRA's intraday margin standard replaced the pattern day trader rule, with its four-trades-in-five-days count and its 25,000 dollar minimum, effective 4 June 2026. Brokers may keep applying the old rule while they phase in the new one, until 20 October 2027, so yours may still count day trades. Margin accounts now need equity against intraday exposure, with a 90-day restriction for repeated unmet deficits. Cash accounts were never under the PDT rule; Regulation T's payment rules still apply.

## How it works

Two layers set what a US brokerage customer may do in a day. The Federal Reserve's Regulation T
sets the credit rules for cash and margin accounts. FINRA Rule 4210 sets margin requirements on top
of it for every FINRA member firm. The pattern day trader rule was part of Rule 4210, so FINRA could
remove it, and has.

A firm can always be stricter than either layer. FINRA's
[investor guidance](https://www.finra.org/investors/insights/intraday-margin-requirements) says
so plainly: "Your firm has the authority to impose higher requirements if they choose." What a
customer meets is the rule plus the house policy, and the house policy is the part that differs by
broker.

## What the old rule required

The SEC's [approval order](https://www.sec.gov/files/rules/sro/finra/2026/34-105226.pdf), Release
34-105226 of 14 April 2026, summarises the rule it retired.

- **A day trade** was buying and selling, or selling and buying, the same security on the same day
  in a margin account.
- **A pattern day trader** was any customer with four or more day trades within five business days,
  unless they were 6 per cent or less of the customer's trades in that period.
- **Minimum equity of 25,000 dollars** had to be deposited before the customer could continue day
  trading, and maintained at all times.
- **Day-trading buying power** was the previous close's equity less the maintenance requirement,
  times four for equities. Exceeding it created a special maintenance call.
- **An unmet call** after five business days restricted the account to trading on a cash-available
  basis for 90 days, and funds deposited to meet the requirements had to stay in the account for two
  business days.

The order also notes a gap: because of how a day trade was defined, the old requirements did not
consider zero-days-to-expiration options trading, which the new standard covers.

## What replaced it

[Regulatory Notice 26-10](https://www.finra.org/rules-guidance/notices/26-10), published on 20 April
2026, describes the new standard in Rule 4210(d)(2). It replaces the old requirements "in their
entirety" and measures exposure rather than counting trades.

- **Intraday margin level.** Broadly, what the customer could withdraw while still meeting
  maintenance margin, or the deposit needed to meet it.
- **IML-reducing transaction.** Any trade that lowers that level, such as a purchase or a short sale.
- **Intraday margin deficit.** The highest shortfall after such a transaction during the day.

FINRA leaves the method to the firm. It may monitor in real time and block trades that would create
a deficit, or "make a single calculation of an account's intraday margin deficit" at the end of the
day. The rule also lets a firm count FDIC-insured bank sweep balances it operates as a credit,
treat the day's deposits and withdrawals as occurring at the start of the day, and treat the legs
of a spread entered together as simultaneous. Where the order of two activities cannot be shown, the
deficit is computed in the order that produces the highest one.

What happens to a deficit:

| Step | Rule 4210(d)(2), as described in Notice 26-10 |
|---|---|
| Satisfy it | "As promptly as possible", by net deposits or an increase in the account's margin level from the end of that day to the end of a later one |
| It lapses | Outstanding until satisfied or until just after the close on the 15th business day |
| 90-day freeze | If the customer "makes a practice" of not satisfying deficits promptly and misses one by the close of the fifth business day, the firm must block new short positions and debit balances for 90 calendar days, or until it is met |
| De minimis | Deficits not exceeding the lesser of 5 per cent of account equity or 1,000 dollars do not count toward the practice |

What did not change, according to FINRA's guidance: 2,000 dollars is still the minimum equity to
trade on margin at all, and maintenance margin is still 25 per cent of the market value of long
margin-eligible equities. What is new is when it applies: under the new requirements it has to hold
"throughout the entire trading day, not just at end of the day". Portfolio margin accounts with less than 5 million dollars in equity must margin intraday
risk on terms substantially similar to end-of-day positions.

## Why brokers still count day trades

The effective date was 4 June 2026, 45 days after the notice. But firms "that need more time to
implement the rule change will be permitted to phase in their implementation over a period of 18
months, until October 20, 2027". The SEC's order describes that period as one in which members may
continue applying the old day trading requirements "as appropriate (e.g., by account)".

So between June 2026 and October 2027 three answers are all compliant:

1. The firm has switched, and nothing counts day trades any more.
2. The firm has not switched, and the four-in-five count and 25,000 dollar minimum still apply.
3. The firm is switching account by account, and two customers of the same broker are on different
   rules.

FINRA's guidance to investors puts it the same way: "Your firm might continue operating under the
old day trading margin requirements during the transition, or they might choose to migrate to the
new system sooner." It tells investors to contact their firm.

House rules sit on top of whichever regime applies. Alpaca's
[help page on the new rule](https://docs.alpaca.markets/us/docs/the-intraday-margin-rule) (updated 7
July 2026) says the PDT designation has been removed there, and that a deficit margin call "must be
satisfied within two business days". That is tighter than FINRA's own timetable, and allowed.

## Cash accounts were never under it

The pattern day trader rule defined a day trade as one made in a margin account. A cash account was
outside it before 4 June 2026 and is outside the new intraday standard after it. What governs a cash
account is Regulation T's [section 220.8](https://www.ecfr.gov/current/title-12/part-220).

- A broker may buy a security for a cash customer if there are sufficient funds, or if it accepts
  in good faith the customer's agreement to pay in full promptly and not to sell before paying.
- Payment is due within one payment period, which section 220.2 defines as the standard US
  settlement cycle plus two business days.
- If a security is sold "without having been previously paid for in full", the privilege of delaying
  payment beyond the trade date is withdrawn for 90 calendar days. The freeze does not apply if full
  payment arrives within the payment period and the sale proceeds are not withdrawn before it.

Brokers name these events in their own terms, but the rule underneath is federal and unchanged by
FINRA's amendments. A customer who moved to a cash account to avoid the PDT count is still subject
to it.

## What it means for software that reads an account

Platforms, journals and scripts that show "day trades remaining" or flag pattern day trader status
are reading the old rule. Whether that number still binds depends on your broker's transition,
not on the software.

Account APIs lag too. Alpaca, whose [market data API](https://stockmarketstack.com/tools/alpaca-market-data) has a card here,
documents its Trading API's account object in a
[reference page](https://docs.alpaca.markets/us/reference/getaccount-1) updated on 27 May 2026. It
still describes the `multiplier` value 4 as a "PDT account with 4x intraday buying power" and
`buying_power` at that multiplier as day-trade buying power computed from the previous day's equity,
while the same broker's help page says the PDT designation is gone. A program that reads those
fields needs the broker's current definition, not the field's name.

## What you can do about it

**Ask your broker which regime your account is on, and from when.** It may be the old rule, the new
one, or a date between now and 20 October 2027. The answer can differ by account at the same firm.

**Read the house rules, not only FINRA's.** Maintenance above 25 per cent, a shorter window to cover
a deficit, or real-time blocking instead of an end-of-day calculation are all permitted. The
broker's margin disclosure is where they are written down.

**Know the two numbers that trigger a restriction.** Under the new standard, a deficit unsatisfied
past the fifth business day, by a customer who makes a practice of it, brings the 90-day freeze;
deficits up to the lesser of 5 per cent of equity or 1,000 dollars do not count toward the practice.

**In a cash account, the clock is settlement, not day trades.** Selling a security before it is paid
for can freeze delayed payment for 90 days under Regulation T, whatever FINRA's margin rule says.

**If your code reads a broker's account fields, re-read their definitions.** Day-trade counters,
PDT flags and buying-power multipliers were built for the old rule. Check the broker's changelog and
reference pages after it switches, and do not hard-code the 25,000 dollar threshold into anything
that will outlive October 2027.

## FAQ

### Is the pattern day trader rule still in effect?

Not as a FINRA requirement for firms that have switched. FINRA's amendments to Rule 4210 took effect on 4 June 2026 and remove the pattern day trader designation and the 25,000 dollar minimum. Firms that need more time may phase in the new standard until 20 October 2027 and, in the SEC's description, may continue applying the old requirements in the meantime, by account if they choose.

### Do I still need 25,000 dollars to day trade?

Not under the new standard. FINRA's investor guidance says there is no 25,000 dollar minimum equity requirement for day trading, while 2,000 dollars remains the minimum equity to trade on margin at all. Your broker can set higher house requirements, and a firm still in its transition period may still apply the old rule to your account.

### What is an intraday margin deficit?

Broadly, the largest shortfall during the day between the margin your positions require and the equity in the account, measured after a trade that reduces the amount you could withdraw, such as a purchase or a short sale. It must be satisfied as promptly as possible, by deposits or by changes to the account that raise its margin level.

### When does the 90-day restriction apply now?

When a customer makes a practice of failing to satisfy intraday margin deficits promptly and leaves one unsatisfied past the close of the fifth business day. The firm must then stop the account creating or increasing a short position or a debit balance for 90 calendar days, or until the deficit is met. Deficits no larger than the lesser of 5 per cent of account equity or 1,000 dollars do not count toward the practice.

### Does the change affect cash accounts?

No. The pattern day trader rule applied to day trades in margin accounts, and the new intraday standard applies to margin accounts. A cash account runs on Regulation T, where selling a security that has not been paid for in full withdraws the privilege of delayed payment for 90 days, unless full payment arrives within the payment period and the proceeds stay in the account until it does.
