What Is Options Trading? Understanding Calls and Puts

An option is a financial contract that gives its buyer the right, but not the obligation, to buy or sell an underlying asset at a set price by a set date. That single feature — a right rather than an obligation — is what sets options apart from other instruments and makes them a distinct corner of the derivatives world. This article explains the concept for education only; it is not a description of a specific product available on any particular platform.

The two basic building blocks

Every option is one of two types:

• Call option: gives the buyer the right to buy the underlying asset at the agreed price (the "strike").
• Put option: gives the buyer the right to sell the underlying asset at the strike price.

The differences between the two are explored in detail in call and put options. A few terms recur throughout options:

• Strike price: the agreed price at which the option can be exercised.
• Expiry: the date by which the decision must be made.
• Premium: the price the buyer pays upfront to acquire the option.

The buyer's key advantage is limited downside: if the option ends up worthless, the most a buyer can lose is the premium paid.

How options differ from futures and perpetuals

It is important not to confuse options with other derivatives. A futures or perpetual contract represents an obligation tied to the price of an asset, whereas an option represents a right the holder may choose not to use. WEEX offers futures and perpetual products; vanilla options are a separate instrument type, and this page does not assert that options are available to trade on WEEX. If you are looking at derivatives on WEEX, those are its futures and perpetual markets.

Options are closely tied to volatility — the concept in volatility (VOL) — because the chance of large price moves directly affects an option's value. In traditional markets, options also connect to settlement mechanics such as the special quotation explained in MSQ.

Why options are considered advanced and risky

Options can behave in complex ways. Their value depends not only on the underlying price but also on time remaining and expected volatility, so they can lose value even when the underlying moves in the expected direction, simply because time passes. For option sellers in particular, the risk can be very large. Options are generally regarded as an advanced instrument that requires study before use.

A worked example

Imagine an asset trading at 100, and a call option with a strike of 110 that expires in one month, bought for a premium of 3.

• If the asset rises above 110, the call gains value, and the buyer's maximum loss remains the 3 premium.
• If the asset stays below 110 until expiry, the option expires worthless, and the buyer loses the 3 premium — but no more.
• The seller of that call, by contrast, collected the 3 premium but took on the risk of a much larger loss if the asset rallied sharply.

This asymmetry — limited, known risk for buyers; potentially large risk for sellers — is central to how options work. Because options are complex, this is educational information only, not a recommendation to trade them, and not a claim that they are offered on WEEX.

Summary

Options are contracts granting the right, not the obligation, to buy (call) or sell (put) an asset at a set price by a set date. They differ fundamentally from futures and perpetuals, which are obligations. Options are powerful but complex and risky, especially for sellers. This page is educational and does not assert that vanilla options are available to trade on WEEX, whose derivative markets are futures and perpetuals.
