If your firm handles margin accounts, FINRA Regulatory Notice 26-11 is required reading. FINRA has published updated interpretations of Rule 4210 specifically addressing the new intraday margin standards, and deleted every interpretation tied to the old day trading margin requirements.
This isn't a tweak. It's a wholesale replacement of the interpretive guidance your margin desk has relied on for years.

What Changed
FINRA's new intraday margin standards replaced the former day trading margin requirements in their entirety. Notice 26-11 does three things:
- Publishes updated interpretations of Rule 4210 aligned with the new intraday margin framework
- Deletes all interpretations relating to the former day trading margin requirements
- Makes available educational resources for customer-facing communications about intraday margin and margin accounts generally
The old interpretations are gone. Not amended. Deleted. Your margin procedures need to reflect this.
What This Means Operationally
The shift from day trading margin to intraday margin standards changes how firms calculate and monitor margin requirements throughout the trading day. The updated interpretations spell out exactly how your operations and compliance teams should handle these calculations. No guesswork.
If you haven't already updated your written supervisory procedures to reflect the new intraday margin framework under Rule 4210, this notice is your cue. The interpretations FINRA deleted were the foundation for how many firms structured their day trading margin procedures. Those procedures are now out of date.
Customer Communications
FINRA's educational resources aren't just nice-to-have. They're a compliance tool. When customers don't understand margin, and most don't, disputes follow. Regulators take note when firms fail to adequately explain margin risks.
You can hand customers FINRA's materials as-is, or use them to tighten up your own disclosures. Either way, don't skip the review. Either way, document that you've reviewed your customer education materials for consistency with the new standards.
Action Items
Here's what needs to happen:
- Review the updated Rule 4210 interpretations — compare them against your current margin procedures and identify gaps
- Update your WSPs — remove references to day trading margin and incorporate the intraday margin framework
- Brief your margin desk — ensure operations staff understand the calculation methodology under the new standards
- Evaluate customer disclosures — incorporate FINRA's educational resources or confirm your existing materials align with the new framework
- Document your review — examiners will ask how you implemented this change
The Bottom Line
This is the kind of change that looks administrative until an examiner asks about it. FINRA replaced the entire interpretive framework for day trading margin. Your firm's procedures need to reflect that replacement, not as a future project, but now.
The educational resources are a straightforward win. Use them. When margin disputes arise, and they will, you want documentation showing you provided clear, FINRA-approved explanations to customers.

Key Takeaways
Do the new intraday margin interpretations apply to all margin accounts or just day traders?
The intraday margin standards under Rule 4210 apply to the calculation of margin requirements throughout the trading day for accounts engaging in intraday trading activity. Review the specific interpretations to determine applicability based on your customer activity profiles.
Can we use FINRA's educational materials directly with customers?
Yes. FINRA explicitly states these resources can be shared with customers to explain the new intraday margin standards and margin accounts generally. You can use them as-is or adapt them to your firm's format while maintaining accuracy.
What happens to our existing day trading margin procedures?
They need to be updated or replaced. FINRA deleted all interpretations relating to the former day trading margin requirements. Any procedures built on that old guidance should be revised to reflect the new intraday margin framework under Rule 4210.
