Exchanges & Alternative Trading Systems
Exchange and ATS Compliance Consulting for the Infrastructure That Markets Run On
Exchanges and alternative trading systems operate at the center of market structure – under direct SEC oversight, with regulatory obligations that are technically demanding, operationally consequential, and continuously evolving. CRC Oyster partners with trading venues of every type and scale, from established exchanges managing complex ongoing regulatory relationships to emerging ATS operators navigating the approval process for the first time.
The CRC Oyster Approach
Exchange and ATS Compliance Requires Market Structure Expertise
The compliance obligations of exchanges and ATSs are distinct from those of the broker-dealers and investment advisers that trade on them. They sit closer to the regulatory infrastructure itself – subject to SEC oversight, responsible for the integrity of the markets they operate, and accountable for surveillance programs that must detect manipulation and rule violations across every participant on the venue.
CRC Oyster brings the cross-disciplinary expertise trading venue compliance requires, spanning market structure regulation, SEC oversight frameworks, surveillance program design, clearing and settlement, and enterprise risk management. We understand both sides of the market access relationship: the regulatory requirements venues must satisfy to operate, and the compliance frameworks governing how participants access them.
What defines our approach:
Market structure depth
Reg NMS, Reg ATS, Form ATS, and SEC exchange registration requirements.
Surveillance expertise
Programs designed for venues where the obligation runs to market integrity itself.
Both audiences
New entrants navigating approval and established venues managing ongoing regulatory relationships.
Enterprise perspective
Compliance, clearing, risk, and technology governance addressed together, not in silos.
Who We Serve
Exchange and ATS Compliance Support Across the Full Range of Regulated Trading Venues
National & Regional Securities Exchanges
SEC-registered exchanges operate under the most comprehensive regulatory framework in market structure, including SRO obligations, rule filing requirements, member regulation responsibilities, and active SEC oversight. CRC Oyster helps exchanges manage the full scope of ongoing compliance obligations, including surveillance, SEC examination readiness, rule filing support, and enterprise risk frameworks
Alternative Trading Systems, ECNs & Dark Pools
ATSs operate under Reg ATS and face Form ATS filing obligations, fair access requirements, and an increasingly active SEC oversight program. CRC yster helps ATS operators build and maintain the compliance infrastructure their venue requires, from initial Form ATS filing through ongoing regulatory maintenance, surveillance program design, and examination readiness.
New Entrants & Emerging Venues
Launching a new trading venue involves a regulatory approval process that is demanding and consequential. The structure of the application, the surveillance program design, and the compliance infrastructure presented to the SEC all shape the approval timeline and the ongoing regulatory relationship that follows. CRC Oyster has guided new entrants through that process.
Established Venues Strengthening Compliance Infrastructure
For venues with existing programs, the challenge is continuous improvement: keeping pace with evolving SEC examination priorities, upgrading surveillance capabilities, managing the rule filing calendar, and ensuring enterprise risk frameworks reflect current operations. CRC Oyster provides ongoing support calibrated to established trading venues.

Market Access Advisory for Exchanges and ATSs
Operating as an exchange or ATS requires regulatory approval before the venue goes live, and continuous regulatory maintenance for as long as it operates.
CRC Oyster helps trading venues navigate the full market access regulatory process:
- Exchange registration – rule development, filing strategy, and SEC review relationship management
- Form ATS filing and maintenance – initial filing, quarterly Form ATS-R reporting, and material change amendments
- Fair access compliance – subscriber access standards, fee structures, and non-discriminatory access documentation
- Reg NMS compliance – order protection, access, sub-penny, and market data obligations
- SEC oversight relationship management – routine information requests, examination coordination, and proactive regulatory engagement
- Rule filing support for registered exchanges – new rules, amendments, and immediate effectiveness filings, coordinated with outside regulatory counsel.
Regulatory Filings, Form ATS Maintenance & Compliance Calendar
Beyond initial registration, exchanges and ATSs face a continuous filing calendar. Missed or deficient filings create regulatory exposure that compounds quickly.
CRC Oyster manages:
- Ongoing Form ATS-R quarterly reports
- Material change amendments as venue operations evolve
- Exchange rule filing calendar – new rules, amendments, immediate effectiveness filings
- Regulatory correspondence – tracking and responding to SEC information requests
- Compliance calendar maintenance across all required filings and deadlines
- Regulatory change monitoring with proactive impact assessment.
Trading Venue Surveillance Frameworks & SEC Examination Readiness
For trading venues, surveillance is a market integrity function; the obligation runs to the integrity of the markets operated, not just the venue’s own regulatory standing.
CRC Oyster designs and assesses trading venue surveillance programs covering:
- Surveillance program design – manipulation detection, wash trading, layering, spoofing, and other market integrity risks
- Alert logic and tuning – parameters calibrated to venue trading volume, participant profile, and risk profile
- Surveillance technology assessment against SEC examination expectations
- Investigation workflow design – escalation procedures and regulatory reporting obligations
- Ongoing surveillance oversight as venue activity and market structure evolve
- SEC examination preparation – alert logs, investigation records, and program methodology documentation.
Enterprise Risk Management for Exchanges and ATSs
Trading venue enterprise risk spans market, operational, technology, regulatory, and reputational risk simultaneously in ways generic frameworks don’t adequately address.
CRC Oyster designs risk frameworks covering:
- Compliance risk assessment attuned to the venue’s operations and regulatory obligations
- Governance design – board reporting, risk committee structure, escalation frameworks
- Operational resilience – business continuity planning where failures carry market-wide implications
- Technology risk governance – compliance risks from infrastructure decisions and third-party dependencies
- Regulatory change management across SEC rulemaking and market structure developments
Clearing Advisory for Exchanges and Alternative Trading Systems
Clearing relationships are operationally foundational and compliance-consequential for trading venues.
CRC Oyster provides:
- Clearing arrangement assessment against operational requirements and regulatory obligations
- Clearing firm evaluation and selection support
- Clearing agreement compliance and operational review
- Participant clearing obligation assessment against venue rules
- Ongoing clearing relationship oversight
Technology Reviews for Trading Venues
For trading venues, technology infrastructure carries direct regulatory compliance obligations; matching engines, order management systems, surveillance platforms, and connectivity infrastructure are all subject to SEC oversight.
CRC Oyster provides:
- Compliance technology assessment against applicable regulatory requirements
- Change management review against SEC expectations for system changes
- Cybersecurity and operational resilience review
- Third-party technology vendor assessment
- Gap assessment and prioritized remediation roadmap
Frequently Asked Questions
A registered exchange is an SRO subject to full SEC oversight, member regulation, and rule filing obligations. An ATS operates under Reg ATS as a broker-dealer with additional venue-specific obligations. The compliance programs required differ significantly; CRC Oyster assesses which structure fits a new venue and builds accordingly.
With a clear picture of the venue’s business model, trading activity, and participant profile, because those factors determine Form ATS requirements, fair access obligations, and surveillance program design. CRC Oyster conducts that assessment before any filing is made.
Active and increasing. The SEC’s Division of Trading and Markets has expanded its examination program for both registered exchanges and ATSs, with particular focus on surveillance adequacy, fair access compliance, and technology governance.
It creates an integrated compliance obligation. Reg ATS requirements sit alongside existing FINRA supervisory obligations and both need to be managed coherently. CRC Oyster builds programs that address both dimensions without gaps at the intersection.
CRC Oyster manages the compliance and operational dimensions of the rule filing process. Legal review is provided by outside regulatory counsel, with whom we coordinate closely.
