Over-the-Counter Trading Depth Guide: Exploring the True Face of the OTC Market

When investors look for promising targets but cannot find this stock on mainstream exchanges, they often need to turn to another vast investment world—the over-the-counter (OTC) market. What opportunities and traps are hidden in this market? How can one protect oneself in an environment lacking central regulation? This article will comprehensively reveal the operating logic of OTC trading.

The Essence of OTC Trading: A Decentralized Trading Network

Over-the-counter (OTC) trading does not occur on formal centralized exchanges but is conducted through banks, brokers, electronic platforms, or direct contact, completing buy and sell transactions at dispersed trading points. This market is also known as “pink sheets,” “OTC markets,” or “over-the-counter markets.”

Unlike the unified bidding method of centralized markets, OTC prices are entirely negotiated between trading parties. In this market, counterparties are diverse—potentially banks, brokers, corporations themselves, or individual investors. This decentralization grants OTC trading unique flexibility but also presents management challenges.

Who Participates in OTC Trading?

Companies that cannot be listed on exchanges or have not applied for listing—especially smaller firms or startups—are often the main participants in OTC trading. However, this is not an absolute rule—some companies that meet listing criteria choose OTC trading to avoid excessive disclosure requirements and the resulting competitive pressures.

With the development of the internet and increasing investor demand for trading convenience, the OTC market has rapidly expanded. The low entry barriers and flexible trading rules make this market a destination for many capital flows. However, due to the lack of strict regulatory frameworks and disclosure requirements, OTC trading carries higher risks, including counterparty credit risk.

Asset Classes Traded in OTC Markets

OTC markets are not limited to stocks. The main trading varieties include:

Stocks and Bonds: Besides listed stocks, OTC markets host many unlisted or non-compliant small company stocks. Bonds are particularly common in OTC trading due to their large issuance volume, variety, and lower trading frequency, making OTC more suitable for such assets.

Financial Derivatives and Contracts: Options, futures, CFDs, and other structured products are mainly traded OTC, providing investors with more risk hedging and leverage tools.

Foreign Exchange and Cryptocurrencies: Global currency trading is almost entirely OTC. Cryptocurrency trading highlights OTC advantages—investors can purchase large amounts of crypto in one go, which is often difficult on centralized exchanges.

How OTC Trading Works: A Case Study of Taiwan Market

Taiwan’s OTC market is operated by the OTC Securities Exchange (commonly called the OTC Center). Its mechanism is almost identical to that of listed markets, with differences mainly in company size and listing standards.

Operational Process includes three steps: investors place orders with brokers → brokers upload orders to the OTC Center’s Automated Trading System (ATS) → ATS matches trades based on “price priority, time priority.” The technical rules are synchronized with the listed markets, requiring no additional operations or special features.

Trading Hours and Rules:

• Pre-market session: 08:30–09:00
• Regular trading hours: 09:00–13:30
• After-hours pricing: 13:40–14:30
• Matching frequency: every 5 seconds
• Price fluctuation limit: ±10% (same as listed rules)

The OTC market shares the same trading mechanisms as the listed market—call auctions, matching trades, and intraday trading time limits. Therefore, the barrier to participation for ordinary investors is not high.

Settlement follows T+2 (settlement two working days after trade), identical to listed stocks. Listed companies must comply with disclosure regulations (quarterly reports, annual reports, major announcements), making OTC market transparency higher than the emerging market, allowing investors to access relatively sufficient information.

The Taiwan OTC Center compiles the OTC Index (also called the OTC Composite Index), reflecting the overall condition of the OTC stock market. Many investors use it to gauge the performance of small- and medium-sized stocks.

OTC Trading vs. On-Exchange Trading: Seven Dimensions Comparison

The purpose of on-exchange trading is to set “standards” for trading, thus rules are more stringent. OTC trading is closer to the fundamental supply and demand laws of economics, with inherent differences:

Product Standardization: On-exchange markets resemble banks offering uniform services, while OTC markets are like pawnshops with unique offerings—more varied but less standardized.

Trade Mode Trade-offs: Call auctions are transparent but profit margins are limited. Negotiated OTC trades offer more bargaining space but rely heavily on information advantage—familiar participants can earn excess returns, while inexperienced investors face higher risks.

Regulation and Security: On-exchange markets are regulated by government agencies, offering participant protections. OTC markets operated by brokers are less regulated, posing risks of fraud, such as fake exchanges set up by malicious actors. Investors must verify platform licenses and regulatory status.

Liquidity Considerations: On-exchange trading benefits from regulation and international capital inflows, resulting in higher liquidity. OTC investors may face “quoted but not traded” situations, making it difficult to cash out at desired prices.

Trading Flexibility: On-exchange markets enforce strict risk controls; leverage and short-selling are limited. OTC markets are less restrictive, allowing higher leverage but increasing risk.

Three Major Advantages of OTC Trading

Multi-Dimensional Investment Options: OTC opens access to derivatives, binary options, forex, and other multi-layered markets, greatly expanding portfolio construction beyond centralized markets.

Flexible Trading Operations: Trading methods and product specifications can be tailored to investment goals, unconstrained by standardized products.

Leverage Opportunities: Traditional markets offer limited leverage, while OTC markets provide various leverage options, enabling investors to amplify capital efficiency and expected returns.

As regulatory frameworks improve, many brokers are licensed and supervised by reputable financial institutions, significantly enhancing OTC market safety and approaching the security level of centralized markets.

Hidden Risks and Dangers of OTC Trading

Lack of Regulation and Fraud Risks: OTC markets lack unified rules and transparency, making them prone to fraud by unscrupulous brokers. In contrast, listed companies and securities must comply with regulations, with better risk controls. Many companies that cannot meet exchange requirements operate OTC, with varying quality.

Liquidity Shortfalls: OTC securities have much lower liquidity than centralized markets, making it difficult to obtain desired prices or even to sell.

Market Volatility Risks: Like stocks, OTC assets are affected by market fluctuations. Unlike centralized exchanges, OTC investors often lack transparent market information, creating asymmetries that advantage some participants.

Counterparty Risks: Negotiated prices mean sellers may quote different prices to different buyers. Additionally, some malicious actors may use false information to scam investors. Certain assets are highly volatile and illiquid, further amplifying these risks.

Is OTC Trading Safe? How Should Investors Evaluate?

OTC trading is not inherently safe—compared to centralized trading, it carries corresponding risks, but these can be managed effectively.

First, assess broker credentials. Reputable brokers should be regulated at multiple levels and have strong risk management capabilities. Investors should verify that platforms hold government-issued licenses, such as ASIC (Australia), CIMA (Cayman), FSC (Mauritius), etc.

Second, choose mature, liquid trading products. Forex is a typical mature OTC product; investors should understand spreads, liquidity, deposit/withdrawal convenience, and other factors.

Third, review platform investor protection measures. Legitimate platforms should have risk assessments, KYC procedures, complaint mechanisms, and other safeguards to reduce trading risks.

OTC Trading and Taiwan Market Ecosystem

Taiwan’s stock market consists of two pillars: the Stock Exchange and the OTC Securities Center. This dual structure aims to ensure listed companies meet certain standards while avoiding overly strict regulations that hinder new enterprises. Many startups with innovative potential lack funds to scale, making OTC a vital alternative.

To address this, the government established the OTC Center and relaxed OTC listing conditions—companies need only two or more broker recommendations to qualify. If within six months they achieve profitability or improved financial health, they can apply to transfer to the main or OTC markets.

However, lowered thresholds have also led to market chaos. Besides genuine high-potential but underfunded companies, some unscrupulous firms enter the OTC space. Some fraudsters impersonate brokers, recommending high-risk targets and manipulating prices to extract retail investor funds—this is the so-called “pink sheet” scam.

Therefore, investors aiming to profit from OTC markets must possess two skills: the ability to select quality targets and the judgment to identify reputable brokers.

OTC Investment Decision Guide

Before participating in OTC trading, investors should conduct systematic assessments:

Platform Selection: Prioritize brokers regulated by multiple authorities, with good reputation and comprehensive risk management tools.

Product Choice: Start with mature, liquid assets (e.g., forex, well-known cryptocurrencies), then gradually explore derivatives and complex products.

Risk Management: Set clear stop-loss and take-profit levels, use leverage cautiously to avoid margin calls.

Information Gathering: Learn basic technical analysis, fundamental analysis, and market psychology to reduce losses caused by information asymmetry.

Capital Management: Treat OTC funds as risk capital, allocate a proportion lower than overall portfolio to prevent single-market downturns from impacting the entire investment.

OTC trading offers opportunities but also hidden traps. Success depends on sufficient knowledge, risk awareness, and self-discipline. Properly leveraging OTC flexibility and diversity can lead to outsized gains, but reckless actions may result in principal loss. Opportunities and risks coexist—wisdom and caution are essential.
