The PDT Rule Is Gone: What FINRA's New Intraday Margin Standards Replace It With

On April 14, 2026, the SEC approved FINRA's proposed amendment to Rule 4210, eliminating the Pattern Day Trader designation entirely. The $25,000 minimum equity requirement that has restricted retail traders since 2001 is gone. So is the four-day-trades-in-five-days counting mechanism. What replaces it is a real-time intraday margin framework that is, in some ways, more demanding, not less.

This article explains the mechanics of the change, sourced from SEC Release No. 34-105226 and the underlying SR-FINRA-2025-017 filing, and what it means in practice if you run automated strategies on a margin account.

Why the PDT rule existed

The Pattern Day Trader rule was created in 2001 following the dot-com collapse, when regulators watched retail traders accumulate losses in fast-moving markets with no mechanism to slow them down. The $25,000 minimum was intended as a capital buffer: the reasoning was that traders with more skin in the game would exercise more care.

The rule was designed for an era when intraday risk management was manual and brokers had limited ability to monitor exposure in real time. That era ended. FINRA's own filing (SR-FINRA-2025-017, published in the Federal Register on January 14, 2026) stated that the PDT framework "no longer aligns with the needs of the investing public" and placed "unnecessary burdens on customers and members" that modern risk infrastructure can handle differently.

What the new intraday margin system does

The replacement framework, established through SR-FINRA-2025-017 (filed December 29, 2025 and published in the Federal Register on January 14, 2026), requires broker-dealers to monitor customer intraday margin exposure in real time throughout the trading session. Margin requirements are now based on actual position risk rather than a fixed equity threshold. The SEC's approval of this change is documented in Release No. 34-105226, dated April 14, 2026.

The specific changes under the new framework:

• The $25,000 minimum equity requirement is eliminated. The minimum equity to open a margin account remains $2,000, unchanged.
• Trade counting is gone. There is no definition of a "pattern day trader" under the new rules.
• Margin requirements are calculated based on the volatility and size of open intraday positions, not on how many trades you placed that week.
• A de minimis threshold protects smaller accounts: a customer is not considered to be in violation where the intraday margin deficit does not exceed the lesser of 5% of account equity or $1,000.
• Accounts previously restricted to liquidating transactions only due to PDT flags are no longer subject to that restriction.

Who benefits, and who needs to pay attention

The clearest beneficiaries are retail traders who had active strategies but could not maintain $25,000 in a margin account. If you had a system with positive expectancy and a $10,000 account, the PDT rule was a structural barrier with no relationship to your actual risk. That barrier is gone.

For traders already above $25,000, the day-to-day change is less dramatic, but the shift to real-time margin monitoring matters. Under the old framework, a large account could absorb day trade exposure passively because the rule was about equity, not position risk. Under the new system, your margin exposure is calculated dynamically throughout the session. A concentrated intraday position can generate a real-time margin requirement regardless of your account size.

What to expect during the transition

The new rules take effect 45 days after FINRA publishes its official Regulatory Notice, which must go out within 45 days of the April 14 approval. Brokers that need time to upgrade their intraday margin systems have an 18-month phase-in period from the date of that notice.

In practice, this means your broker may still be operating under PDT rules for some months yet. Expect variation across brokers during the transition. Some will move quickly; others will use close to the full 18 months. Check your broker's official communications before assuming the change is already in effect for your account. Broker guidance pages like the ones E*TRADE and similar platforms publish are the right place to track implementation status.

What it means for automated traders specifically

If you run bots that execute multiple intraday round trips (entries and exits within the same session), the PDT rule was either limiting how you sized accounts or forcing strategies only into accounts large enough to stay clear of the restriction. That constraint is gone.

The more significant shift is in how margin works during live execution. Automated strategies that hold intraday positions across multiple instruments, or that scale into positions progressively, need to account for real-time margin calculations that change as positions open and close. A bot sized for a $25,000 PDT-compliant account may need its position sizing reviewed under the new framework, not because the rules are stricter, but because the margin math is now dynamic rather than static.

PDT Tracker and what margin visibility means going forward

RelayDesk includes a PDT Tracker that monitors your day trade count and account equity status. Under the old rules, this was primarily a compliance tool for avoiding accidental PDT violations. Under the new framework, the value shifts toward real-time margin visibility: knowing your intraday exposure as it changes is more relevant than counting trades.

The PDT Tracker remains directly useful during the transition period while brokers implement the new system. After full implementation, the relevant question for any automated strategy running on margin is not how many day trades you made this week, but what your real-time margin position looks like right now. That question requires the same account visibility, and RelayDesk gives you a centralized view of it across your connected brokers.
