Day Trading Rules: What Firms Need to Know in 2026

And unfortunately, for those who don’t: FINRA Rules 2130, 2270 and 4210

By Mark J. Astarita, Esq.

Originally published November 2000 under NASD Rules 2360 and 2361. Updated October 2026.

Note: This article was first written in November 2000 and is presented in part for historical reference. It was updated in October 2026, but rules and their interpretations change. It is general information, not legal advice, and you should not rely on it without checking the current rules or talking to counsel.

When I first wrote this article in 2000, the NASD had just adopted Rules 2360 and 2361, its new day-trading rules, effective October 16, 2000. Those rules are still with us. They now sit in the FINRA rulebook as FINRA Rule 2130 (Approval Procedures for Day-Trading Accounts) and FINRA Rule 2270 (Day-Trading Risk Disclosure Statement), and they became FINRA rules effective February 15, 2010 (SR-FINRA-2009-059; Regulatory Notice 09-72). The substance has changed very little.

What has changed, and changed a lot, is margin. In 2026 FINRA got rid of the “pattern day trader” rules and the $25,000 minimum equity requirement that brokers and traders have dealt with for about a quarter century. It replaced them with a new intraday margin standard under FINRA Rule 4210. I cover that below. It is the biggest change to day trading regulation since this article was first written.

The Account Approval Rule: FINRA Rule 2130

A firm that is “promoting a day-trading strategy, directly or indirectly,” cannot open an account for a non-institutional customer unless, before opening the account, it has furnished the Rule 2270 risk disclosure statement and has either:

1. approved the customer’s account for a day-trading strategy and prepared a record setting forth the basis for that approval; or
2. received from the customer a written agreement that the customer does not intend to use the account for day trading. The firm may not rely on that agreement if it knows the customer intends to day trade.

(Rule 2130(a).)

To approve the account, the firm must have reasonable grounds for believing that day trading is appropriate for the customer. It must exercise reasonable diligence to ascertain the essential facts about the customer, including: investment objectives; investment and trading experience and knowledge (e.g., years, size, frequency and type of transactions); financial situation (estimated annual income, estimated net worth exclusive of family residence, and estimated liquid net worth); tax status; employment status; marital status and number of dependents; and age. (Rule 2130(b).) The records must be preserved under FINRA Rule 4511. (Rule 2130(d).)

A “non-institutional customer” is any customer that does not qualify as an “institutional account” under FINRA Rule 4512(c). A “day-trading strategy” is “an overall trading strategy characterized by the regular transmission by a customer of intra-day orders to effect both purchase and sale transactions in the same security or securities.” (Rule 2130(e).) In 2000 I complained that there was no definition of day trading. There is one now, but “regular” is still doing a lot of work in it.

As I said in 2000, none of this should be a hardship. It belongs in the new account process. Most firms already collect this information for Regulation Best Interest, FINRA Rule 2111 (suitability) and FINRA Rule 2090 (know your customer). The day-trading questions are just one more page. The real burden is monitoring. Compliance has to make sure that anyone who is actually day trading has been approved and that the paperwork is in place.

What Is “Promoting” a Day-Trading Strategy?

The rules still apply only to firms that promote a day-trading strategy. The guidance I discussed from NTM 00-62 has since been written into the rule itself as Supplementary Material .01 to Rule 2130. A firm is deemed to be promoting day trading if it affirmatively endorses a day-trading strategy “through advertising, its Web site, trading seminars or direct outreach programs.” A firm generally will be deemed to be promoting day trading if its retail communications “address the benefits of day trading, rapid-fire trading, or momentum trading, or encourage persons to trade or profit like a professional trader.” Promoting day-trading services through a third party counts too.

A firm is not deemed to be promoting day trading solely by:

1. promoting efficient execution services or lower execution costs based on multiple trades;
2. providing general investment research or advertising the high quality or prompt availability of that research; or
3. having a Web site that provides general financial information or news, or that allows the multiple entry of intra-day purchases and sales of the same securities.

The “ominous sentence” I warned about in 2000 is now rule text: “the fact that many of a member’s customers are engaging in a day-trading strategy will be relevant in determining whether a member has promoted itself in this way.” (Rule 2130.01(a).) My concern from 2000 still stands. A firm that never advertises day trading, but whose customers day trade heavily, should not assume it is outside the rule. Look also at how today’s apps and “finfluencer” relationships present trading. A third-party promoter can bring a firm within the rule.

A firm that is unsure whether its retail communications cross the line can submit them to FINRA’s Advertising Regulation Department for review and guidance. (Rule 2130.02; Rule 2270.01.)

The “I Won’t Day Trade” Agreement

Firms will still be tempted to use the customer’s written agreement not to day trade as a way out of the approval process. That is still a short-sighted decision. The firm cannot rely on the agreement if it knows the customer intends to day trade. If, after the account is opened, the firm knows the customer is using the account for a day-trading strategy, it must approve the account under Rule 2130(a)(1) “as soon as practicable, but in no event later than 10 days following the date that such member knows” of the day trading. (Rule 2130(c).)

The Risk Disclosure Statement: FINRA Rule 2270

Rule 2270 (formerly NASD Rule 2361) requires a firm that promotes day trading to furnish the prescribed Day-Trading Risk Disclosure Statement to each customer individually, in paper or electronic form, before opening the account. Since 2000 one requirement has been added: the firm must also post the statement on its Web site “in a clear and conspicuous manner.” (Rule 2270(a).)

The statement covers these points:

• Day trading can be extremely risky. It generally is not appropriate for someone of limited resources, limited investment or trading experience, and low risk tolerance. Customers should be prepared to lose all of the funds they use for day trading, and should not use retirement savings, student loans, second mortgages, emergency funds, or money needed for living expenses. The statement also notes evidence that an investment of less than $50,000 significantly impairs a day trader’s ability to make a profit.
• Be cautious of claims of large profits from day trading.
• Day trading requires knowledge of securities markets.
• Day trading requires knowledge of a firm’s operations, including the risks of halts, volatility and system failures.
• Day trading will generate substantial commissions, even if the per trade cost is low. (The rule’s example still assumes a $16 commission and 29 trades a day. In a zero-commission world it reads as dated, but it is the rule text.)
• Day trading on margin or short selling may result in losses beyond the initial investment.
• Potential registration requirements: people providing investment advice or managing accounts for others may need to register as an investment adviser under the Investment Advisers Act of 1940, or as a broker or dealer under the Securities Exchange Act of 1934, and may trigger state registration requirements.

A firm may use an alternative statement instead. It must be substantially similar to the prescribed statement and filed with FINRA’s Advertising Regulation Department at least 10 days before use (or a shorter period if FINRA allows). If FINRA recommends changes, the statement must be held back until those changes are made. (Rule 2270(b).)

The rule still does not require the customer to sign the statement. I still strongly recommend getting a signed or electronic acknowledgment of receipt. Perhaps it is my litigation mentality, but customers will not remember receiving the statement when they are testifying in an arbitration.

Margin: The End of the “Pattern Day Trader” Rule

For most of the last 25 years, the day-trading rule most traders actually ran into was not Rule 2130 or 2270. It was the “pattern day trader” margin rule in FINRA Rule 4210(f)(8)(B), adopted in 2001 (originally as an NASD rule). Under that framework:

• A pattern day trader had to maintain minimum equity of $25,000 in the margin account on any day the customer day traded, and could not day trade if equity fell below that level.

That framework is gone. On December 29, 2025, FINRA filed SR-FINRA-2025-017 to replace the day trading margin provisions with intraday margin standards. The SEC published the proposal for comment (Exchange Act Release No. 34-104572, 91 FR 1580 (Jan. 14, 2026)). On April 14, 2026, the SEC approved it on an accelerated basis, as modified by Amendment No. 1 (Exchange Act Release No. 34-105226, 91 FR 20731 (Apr. 17, 2026)). FINRA announced the approval in Regulatory Notice 26-10 (April 20, 2026).

• Effective date: June 4, 2026.
• Phase-in: firms that need more time may phase in implementation over 18 months, until October 20, 2027.

So as of today (October 2026), the new rule is in effect, but a firm may still be operating under the old pattern day trader requirements during the transition. FINRA itself tells investors to ask their firm which regime applies to their account. Traders should not assume the $25,000 minimum is gone at their broker until the broker confirms it.

The New Intraday Margin Rule (Rule 4210(d)(2))

The amendments eliminate Rule 4210(f)(8)(B) and the related day-trading provisions, including the pattern day trader designation, the day-trade counts, day-trading buying power, and the $25,000 minimum equity requirement. In their place FINRA added new definitions in Rule 4210(a)(17)–(19) and a new Rule 4210(d)(2). Regular maintenance margin requirements are unchanged. The new rule supplements them. In summary:

• Intraday margin deficit. For each customer margin account (other than a good faith account or portfolio margin account), the firm must determine the “intraday margin deficit” for each day on which there is an “IML-reducing transaction.” Broadly, that is the largest shortfall during the day between the margin required and the equity in the account after a transaction that reduces the “intraday margin level” (IML). A short sale, or a purchase other than to cover a short, generally reduces IML.
• No mandatory real-time monitoring. Firms may monitor and block trades in real time, but they are not required to. They may instead make a single calculation, much as they do for maintenance margin. The rule gives firms several computation choices: sweep-program bank deposits, more current market values, “as of” actions, deposits and withdrawals treated as occurring at the start of the day, and multi-leg strategies. If the firm cannot show the order in which activities occurred, it must assume the order that produces the highest deficit.
• Satisfaction. The firm must require the deficit to be satisfied “as promptly as possible,” through net deposits or an increase in IML. A deficit stays outstanding until it is satisfied or until the close of business on the 15th business day after it arose.
• 90-day freeze. If a customer makes a practice of failing to satisfy intraday margin deficits as promptly as possible, and fails to satisfy one by the close of business on the fifth business day, the firm must enforce written procedures that prevent the customer from creating or increasing a short position or debit balance for 90 calendar days, or until the deficit is satisfied. Deficits that do not exceed the lesser of 5% of account equity or $1,000, or that the firm reasonably determines arose under extraordinary circumstances, do not count toward a “practice.”
• Portfolio margin. New Rule 4210(g)(1)(J) and (K) require firms to monitor intraday risk in portfolio margin accounts. Accounts with less than $5 million in equity must maintain margin for intraday risk substantially similar to what is required for end-of-day positions.

A Note on Rule 2130 and 2270 Cross-References

Supplementary Material .03 to Rule 2130 and .02 to Rule 2270, as currently posted on FINRA’s website, still cross-reference “Rule 4210(f)(8)(B)” for day-trading margin. The 2026 amendments eliminated that paragraph. FINRA may make conforming changes. The approval and disclosure obligations in Rules 2130 and 2270 were not repealed by the margin reform and remain in force.

What Firms Should Do Now

My advice from 2000 still applies. There is still a regulatory landmine waiting for the weary compliance department. Review your active accounts to identify the day traders at the firm. You already have a way to identify active accounts, so use it. This is an excellent opportunity to do a suitability and Reg BI review and to make sure those accounts have the proper disclosure statement and firm approval. And remember that the 10-day clock under Rule 2130(c) still runs once you know a customer is day trading.

In 2026, add these items to the list:

• Decide on, and document, your intraday margin implementation timeline before October 20, 2027. Update your written supervisory procedures and margin agreements, and tell customers which regime applies to them.
• Expect more day trading in smaller accounts. With the $25,000 floor gone, accounts that could never day trade on margin before now can. Firms that “promote” day trading will see more Rule 2130 approvals. Firms that don’t should watch whether a growing share of day-trading customers pulls them into the rule anyway.
• Revisit your marketing. App features, push notifications, and social media and influencer programs should all be reviewed against the Rule 2130.01 definition of “promoting.”
