What Is the Series 57 Exam?

The Series 57, officially known as the Securities Trader Representative Exam, is a licensing examination administered by the Financial Industry Regulatory Authority (FINRA). It is required for individuals who engage in equity trading activities on behalf of a broker-dealer, particularly those involved in trading Nasdaq or over-the-counter (OTC) securities. This exam ensures that professionals understand the regulatory and operational framework necessary to execute and manage trades in compliance with federal securities laws.

The Series 57 exam is part of FINRA's broader licensing structure designed to ensure that registered representatives have the qualifications necessary for their specific roles. Passing this exam is a requirement for individuals who are functioning as proprietary traders, institutional traders, or other professionals whose primary responsibility involves executing orders or maintaining markets in securities.

Historical Context and Purpose

The Series 57 was introduced in January 2016 as a consolidation of prior licensing exams, specifically the Series 55 (Equity Trader Exam) and, in some cases, elements of the Series 56, which had been administered to proprietary traders. FINRA created the Series 57 in response to the evolving structure of equity markets and to create a more uniform standard for licensing equity traders across different types of trading platforms and institutions.

Prior to the creation of the Series 57, the industry faced inconsistencies in trader qualification requirements depending on the business model of the firm or the exchange involved. The new exam aimed to bring greater consistency to the registration process and to align it more closely with modern market operations and technologies.

Exam Structure and Requirements

To be eligible to take the Series 57, a candidate must first pass the Securities Industry Essentials (SIE) Exam, which tests basic industry knowledge and is a prerequisite for most FINRA representative-level exams. Once the SIE is complete, the candidate can take the Series 57 to qualify as a Securities Trader Representative.

The Series 57 exam contains 50 scored multiple-choice questions (plus an additional 5 unscored questions used for research purposes). Candidates are given 105 minutes to complete the exam. The passing score is 70%.

Unlike some other FINRA exams, the Series 57 is focused specifically on trading and market making activities. It does not cover topics related to sales, retail customer interaction, or investment advisory services.

Content Covered

The Series 57 exam focuses on two primary areas:

1. Trading Activities (80%): This section covers the rules and practices related to executing trades, handling orders, reporting transactions, and maintaining market integrity. It includes:

• Order types and routing
• Market making obligations
• Limit and stop orders
• Trade reporting requirements
• Short sale regulations
• Order audit trail system (OATS)
• Market manipulation rules

2. Regulatory Compliance (20%): This portion covers knowledge of applicable securities regulations and procedures that govern equity trading, including:

• SEC rules (such as Regulation NMS)
• FINRA rules and guidelines
• Anti-fraud provisions
• Market access and supervisory controls

Together, these domains ensure that a trader understands how to operate within the bounds of regulatory expectations while maintaining orderly and fair markets.

Who Needs the Series 57 License

The Series 57 license is required for individuals who engage in proprietary or agency trading of equity securities. This includes traders at broker-dealers who:

• Execute trades on behalf of institutional or retail clients
• Make markets in Nasdaq or OTC securities
• Conduct proprietary trading for the firm’s own account
• Handle order flow or perform supervisory functions over traders

It is especially relevant for professionals working in firms that are FINRA-member broker-dealers participating in Nasdaq, OTC, or alternative trading systems (ATS). However, it does not cover individuals whose primary role is advising clients, managing portfolios, or engaging in mutual fund sales—those roles require different licenses such as the Series 7 or Series 65.

Registration and Sponsorship

To take the Series 57, a candidate must be sponsored by a FINRA-member firm. This means that the firm must submit a Form U4 (Uniform Application for Securities Industry Registration or Transfer) on behalf of the candidate. Individuals cannot self-register for the exam.

After passing the Series 57, the individual is registered as a Securities Trader Representative (TD). This designation must be maintained through continuing education and firm supervision, and it may be subject to additional regulatory obligations depending on the scope of the individual's activities.

Relationship to Other Licenses

The Series 57 is distinct from broader licenses like the Series 7, which covers a wide range of securities and customer interaction responsibilities. The Series 57 is narrowly tailored to focus on trading functions only.

If a trader’s responsibilities expand to include activities such as dealing directly with retail clients or providing investment advice, additional licenses would be required. However, for a professional whose sole responsibility is trade execution and market making, the Series 57, along with the SIE, is sufficient.

Continuing Obligations

Registered representatives holding a Series 57 must comply with FINRA continuing education (CE) requirements. This includes participation in both Regulatory Element training, administered by FINRA, and Firm Element training, provided by the employer. These components are designed to ensure that traders stay informed about rule changes, emerging market practices, and ongoing compliance responsibilities.

If a registered individual leaves the industry, their Series 57 registration remains valid for two years. After that period, if they return to a trading role, they must retake the exam unless they maintain their registration through certain eligible programs or exemptions.

The Bottom Line

The Series 57 exam plays a critical role in regulating the individuals responsible for the trading infrastructure of U.S. securities markets. It ensures that traders have a working knowledge of market operations, trading protocols, and compliance obligations. For anyone pursuing a professional role in equity trading through a broker-dealer, especially in a market-making or proprietary trading capacity, obtaining the Series 57 license is both a regulatory requirement and a foundational step in their career development.
