What are currency options and how do you trade them?

Currency options can seem intimidating at first, but they’re easy to understand once you’ve got the basics. Here, we go through what currency options are, the essentials of FX options trading, and how to open an account.

What are currency or forex options?

Currency options – or forex options – give the holder the right, but not the obligation, to buy or sell a currency pair at a given price before or on a set expiry date.

To be granted this right, the buyer of the option pays a premium to the seller. When trading options, it’s important to know that the buyer is often referred to as the ‘holder’, and the seller is often referred to as the ‘writer’.

Essentials of FX options trading

Before trading forex options, there is some essential terminology that you’ll need to be familiar with:

  • Strike price – the predetermined price of the options contract that you can either buy or sell the contract for at or before expiry
  • Expiry date – the date at which your options contract will need to be settled, but it can be closed before the expiry date arrives
  • Premium – the fee that the writer receives from the holder for taking on the obligation to buy or sell the underlying
  • Implied volatility (IV) – is a measure of the implied risk in an options contract, relative to the price of the underlying market. Implied volatility will affect the price of an options contract
  • In the money – an options contract is in the money when it can be exercised for a profit
  • At the money – an options contract is at the money when its strike price is the same or similar to the price of the underlying market – meaning it could expire with value, or worthless
  • Out of the money – an options contract is out of the money when it cannot be exercised for a profit

How do currency options work?

There are two types of currency options: calls and puts. Buying a call option gives the holder the right to buy a currency pair for the strike price on or before the expiry date, and buying a put option gives the holder the right to sell a currency pair for the strike price on or before the expiry date.

If the expiry arrives and the market price of a currency pair is above the strike price when buying calls, or below the strike price when buying puts, a trader can choose to exercise it. This means they can buy or sell the currency for a better price than what is currently available in the underlying market.

But if this doesn’t happen, a trader can let their option expire, and they’ll only lose the value of the premium. As a result, buying call or put options means that a trader’s upside is potentially unlimited, and their downside is capped at the premium.

On the other hand, traders can also sell call options and put options – which obliges them to sell a currency pair in the case of a call, and to buy a currency pair in the case of a put. For taking on this obligation, the seller of a call or put option will receive a premium.

If a trader is taking on the obligation to sell an options contract, their losses are potentially unlimited – and profits are capped at the total value of the option premium. When selling options, a trader is hoping that the price of a call option remains below the strike price, and the price of a put option remains above the strike price.

There is more information about the mechanics of buying or selling call and put options below.

Buying or selling call options

  • Buying call options gives a trader the right but not the obligation to buy a currency pair for a predetermined price, at or before a set date in the future
  • Selling call options gives a trader the obligation to sell a currency pair for the predetermined price, if the buyer executes their right to buy – and they’ll receive a premium for doing so
  • Buying call options gives unlimited upside with a capped loss, while selling call options gives an unlimited downside and a capped gain – the option premium

Buying or selling put options

  • Buying put options gives a trader the right but not the obligation to sell a currency pair for a predetermined price, at or before a set date in the future
  • Selling put options gives a trader the obligation to buy a currency pair for the predetermined price, if the buyer executes their right to sell – and they’ll receive a premium for doing so
  • Buying put options gives unlimited upside with a capped loss, while selling put options gives an unlimited downside and a capped gain – the option premium
