Recently, I’ve been reading discussions in investment communities and found that many people still have a bit of confusion about what the OTC market is. Actually, simply put, OTC means over-the-counter trading—investors don’t trade on centralized exchanges; instead, they buy and sell securities directly through banks, brokerages, or electronic systems. This market is also called over-the-counter trading.

I’ve noticed that many people ask why they would trade OTC instead of going directly to an exchange. The main reason is that some companies simply don’t meet the qualifications to be listed—mostly small and medium-sized enterprises or startups. But there are also some companies that deliberately choose over-the-counter trading even though they do meet listing requirements, because listing rules are too strict, information disclosure is more extensive, and competitive pressure is higher. In the over-the-counter market, the two trading parties negotiate the price directly, which offers far more flexibility than the centralized market.

Taiwan’s OTC market is divided into two parts: the Securities Exchange and the over-the-counter trading center. The OTC index compiled by the over-the-counter trading center reflects conditions in the small and medium-sized stock market. The government established this mechanism to lower the listing threshold for companies. As long as they are recommended by more than two advisory brokerages, they can register. If the company performs well within six months, it can apply to transfer to a listed status. This was originally a good design, but because the threshold is low, it’s inevitable that some questionable companies get mixed in.

When it comes to how the over-the-counter market actually operates, it’s basically similar to the process for listed stocks. You place an order through a brokerage, and the order is uploaded to the over-the-counter trading center’s automatic matching system. The system matches trades using price priority and time priority. There is a call auction every 5 seconds, and the price fluctuation limit is also ±10%, exactly the same as listed stocks. The settlement system is T+2, meaning settlement is completed two business days after the trade.

Compared with on-exchange trading, the advantages of OTC are quite clear. First, products are more diverse—not just stocks and bonds, but also foreign exchange, cryptocurrencies, derivatives, and more. Second, trading methods are more flexible: you can tailor them according to your needs, and you have more options for leverage. Over-the-counter trading has less stringent risk-control restrictions, so shorting or using high leverage is generally easier.

However, risks do exist as well. The OTC market lacks unified rules and transparency, and regulatory oversight is relatively relaxed, which gives some bad actors opportunities. Liquidity is also worse than on-exchange trading, so exiting quickly can be difficult. Most importantly, you face counterparty credit risk. For certain products, prices may swing a lot while liquidity is low, and you also need to watch out for scams involving false information.

So, is OTC over-the-counter trading actually safe? To be honest, without the exchange’s strict regulation there is indeed risk, but it’s not absolutely unsafe either. The key is to choose the right broker. A legitimate trading platform should be subject to multi-layer regulation and have strong risk-management capabilities. Second, you should choose mature trading products—such as foreign exchange—and understand details like spreads and liquidity. Some reputable platforms also provide investor protection measures, such as risk assessments, KYC identity verification, and complaint-handling mechanisms.

So if you want to “mine gold” through over-the-counter trading, the first step is to find a reputable and regulated broker. The second step is to choose mature trading products and not be misled by promises of high returns. The third step is to understand risk management and make good use of tools like limit orders and stop-losses. As long as you do these things, the risks of trading in the OTC market are actually manageable.
