Recently, many friends have asked me how to trade derivatives, so I decided to compile a list of common questions to help everyone.

First, it’s important to understand what derivative financial products are. Simply put, they are investment tools derived from underlying assets such as stocks, foreign exchange, commodities, and indices. Their value changes with the price fluctuations of the underlying assets. I think the biggest feature is that you can control a larger amount of assets with only a small amount of margin—this is the leverage effect. For example, if you want to invest in Bitcoin, you can buy 1 BTC directly, or you can trade Bitcoin derivative contracts—by depositing only a small portion of margin, you can participate, and your costs are indeed much lower.

So why do some people trade derivatives? There are mainly three reasons. The first is speculation, which amplifies returns through leverage. The second is hedging risk—many large companies use futures contracts to avoid the risk of price fluctuations. The third is arbitrage—finding opportunities in the price spreads based on market relationships. Personally, I come across speculation and arbitrage more often.

The advantages of derivatives are obvious: good liquidity, low trading costs, and flexible trading, including the ability to trade in both directions. But the drawbacks can’t be ignored either: the rules are complex, the risks are high, and if you choose the wrong platform, you may also face counterparty risk. That’s why choosing a platform with strict regulation is especially important.

There are five commonly seen types of derivatives. Futures are standardized contracts with expiration dates and they are traded on exchanges. Options give you the right to buy or sell, not the obligation, and they also have expiration dates, but the strategies are more flexible. Contracts for Difference (CFD) have no expiration date, are traded over the counter (OTC), and offer the highest leverage. Forward contracts and swap contracts are also non-standardized and are mainly used by institutional investors.

The one I use most often is CFD. Its benefit is that there’s no pressure from an expiration date, so you can hold positions indefinitely. Transaction costs are only the spread and overnight fees, unlike futures which also involve commissions and trading taxes. And you can short directly without needing to borrow securities. However, you should note that OTC trading doesn’t have the protection of a centralized exchange, so you must choose a regulated platform.

As for trading platforms, I recommend first clarifying what derivatives you want to trade. Generally, brokerages mainly offer warrants and options; futures firms provide futures and options; while OTC brokers offer futures, options, and CFDs. There are many choices for investors in Taiwan, such as well-established brokerages like Interactive Brokers and First Securities, as well as some brokers that specialize in CFDs.

I also want to emphasize the risks of trading derivatives. High volatility is an inherent characteristic, and derivative prices can’t be predicted. Improper speculative activity may lead to massive losses, or even liquidation. Therefore, be sure to set stop-loss and take-profit levels and never go all in.

In short, derivative financial products do provide more flexibility and opportunities than traditional stock trading, but they also require more knowledge and risk management. If you’re a beginner, it’s recommended to start with a demo account to practice and understand how different derivatives work, and then move on to real trading with a small amount of capital. Commodity companies and miners can use futures to lock in prices, hedge funds use derivatives to amplify returns, and ordinary investors can use derivatives for short-term speculation or to hedge risk. The key is to choose the right platform, learn the rules well, and manage risk properly.
