Recently, I’ve found that many people still have a bit of confusion about the concept of over-the-counter trading. In fact, OTC means Over The Counter—simply put, it’s a trading method that takes place outside of regular exchanges. I’ve noticed that quite a few investors around me don’t have a deep enough understanding of this market, so I’d like to share my observations.

The core feature of over-the-counter trading is that both the buyer and the seller directly negotiate the price, with no fixed pricing mechanism like the one used by centralized exchanges. This means that for the same stock, a seller might sell at different prices to different buyers. This flexibility really does attract many investors—especially those who want to trade shares of small and mid-sized companies or startups that aren’t listed on major exchanges.

The situation in Taiwan is particularly interesting. The market is divided into two systems: “Securities Exchange” and the “OTC Trading Center.” The OTC index compiled by the OTC Trading Center (also known as the OTC Index) reflects the state of the over-the-counter stock market. The government’s original intention in establishing the OTC Trading Center was to relax entry requirements. As long as a company has recommendations from at least 2 guidance brokers, it can register, giving more startups the opportunity to raise funds. But this has also brought problems—there are indeed plenty of companies that are just “mixed in” among the legitimate ones.

The variety of products in OTC trading is truly much richer than in on-exchange trading. In addition to stocks and bonds, there are also foreign exchange, cryptocurrencies, derivatives, and more. Cryptocurrencies are especially active in the OTC market, because OTC allows large amounts of different coins to be bought at once—something that’s difficult to achieve on specialized cryptocurrency exchanges.

In terms of operations, the trading process in Taiwan’s OTC market is actually quite similar to the listed market. Investors place orders through brokers, and the orders are uploaded to the OTC Trading Center’s automatic matching system. Trades are matched according to price priority and then time priority. There is a call auction every 5 seconds, and the price fluctuation limit is also ±10%, just like listed stocks. The settlement system is T+2, meaning settlement is completed two business days after the trade.

But to be frank, the risks of OTC trading are indeed higher than those of on-exchange trading. The main reasons are that regulation is relatively less strict, information transparency is lower, and the two trading parties may face credit risk. Since there are no unified rules and no public pricing, fraudulent brokers do exist in the market. Also, liquidity for OTC securities is usually lower than that of centralized exchanges, so trades may not get good prices. For certain products with large price swings and low liquidity, the risks are even greater.

The advantages of OTC trading are also obvious. Product specifications are more flexible and diverse, and can be tailored to your own investment goals. Leverage is more flexible, allowing you to use higher leverage to amplify returns. Trading methods are also more diversified, with far fewer restrictions than in the on-exchange market. And it allows you to access more types of investments and a broader range of markets.

For ordinary investors, to protect yourself in OTC trading, the first priority is to ensure that the broker is safe and under proper, legitimate regulation. Second, choose more mature trading products and understand information such as bid-ask spreads and liquidity. Legitimate trading platforms usually have investor protection measures such as risk assessments, customer identity verification, and complaint-handling mechanisms.

So while OTC simply means “over the counter,” truly understanding OTC trading means recognizing that it has both the advantage of flexibility and the risks brought by looser regulation. The key is still to choose the right platform and trading products—don’t get greedy for high leverage or be lured by false information from bad actors. This market does offer opportunities for experienced investors, but for beginners it requires extra caution.
