A one-touch option is one of the most popular exotics that are profitable if the price of the currency pair touches a specified price within a certain period of time. Timing is especially significant with exotic options. Each broker may have different cut-off conventions but exotic options are timed against the New York cut-off, which is 10 a.m. ET. However, some brokers will set the cut-off time at 24:00 GMT (4 a.m. ET), so it is necessary to confirm the time before making a trade.
No-touch options are profitable only when the price of a currency pair does not reach the target by a specified time. A no-touch option offers better payout odds when the strike price is closer to the market price but the expiration date is farther away because the chances the currency will not touch the strike price diminish considerably the longer the trader has to wait. One interesting factor of the no-touch is the fact the underlying currency pair does not have to move away from the strike price in order to produce a profit. The currency pair simply has to stay relatively stagnant for the trader to collect a payout.
Double one-touch In double one-touch option you can select two strike-price barriers that provides a payout if either one is touched. The double one-touch is similar to a standard long strangle or straddle option trade and it is a good tool to use when you have no strong opinion about direction of the price movements but you expect volatility to explode.
Double no-touch
The double no-touch option is just the opposite of the double one-touch. It is appropriate for situations in which you anticipate a range-bound market where there is no clear indication about the direction and expect volatility to be low.
One-touch and no-touch options are precisely time sensitive. A one-touch will be significantly cheaper the less time there is to expiration because the odds of reaching the target is greatly reduced, while a no-touch will be priced opposite to one-touch because the chances of not touching the target will diminish the more time is left on the contract.
However, the double one-touch and double no-touch options will have the same pricing parameters in terms of time but will vary greatly with respect to the volatility. Double one-touch options, for example, will become progressively more expensive as the barriers narrow.
Digital options
Digital options produce a payout only if the spot price meets or exceeds the selected barrier price at expiration. Digital options are less expensive than one-touch options with the same strike and expiration date whereas Digital premiums can be half the price of no-touch options premiums with the exact same strike price and expiration dates, but the trader has to weigh the advantage of lower cost against the risk price will settle even 1 pip below the target at expiration.
Asian options
Asian options are options in which the average price over a period of time is the underlying variable. Because of this, Asian options have a lower volatility and hence are rendered at cheaper relative to their European counterparts. They are commonly traded on currencies and commodity products having low trading volumes.
They are divided into three categories; arithmetic average Asians, geometric average Asians and both these forms can be averaged on a weighted average basis, whereby a given weight is applied to each stock that is being averaged. This is used for attaining an average on a sample with a highly skewed sample population.
Balloon options
An option whose notional payments increase significantly only after a set threshold is broken. It is commonly used in foreign exchange markets and these options provide greater leverage to the holder. The main idea behind the balloon option is that after the threshold is exceeded, there is an increase in regular payout.
Barrier options
Barrier options are path-dependent options which appear in many flavours and forms, but their key characteristic is that these types of options are either initiated or exterminated upon reaching a certain barrier level; they are either knocked in or knocked out.
Basket option
A basket option has all the characteristics of a standard option, except that the strike price is based on the weighted value of the component currencies which is calculated in the buyer's base currency. The buyers order the maturity of the option, the foreign currency amounts which make up the basket, and the strike price is expressed in units of the base currency.
At expiry, if the total value of the component currencies in the spot market is less favourable than that of the strike price of the basket option the buyer would let the option lapse. If it is more favourable, the buyer would exercise the option and exchange all of the component currencies for the pre-specified amount of the base currency (i.e. the strike price of the option).
Digital Option
An option whose payout is fixed only after the underlying stock exceeds the predetermined threshold or strike price is known as Digital option. It is also known as "binary" or "all-or-nothing option."
Embedded Option
An option which is an inseparable part of another instrument is known as embedded option. A common embedded option is usually the call provision in most corporate bonds.
Lock-out option
A lock-out option pays only if the value of the underlying does not go beyond a specified value whereas a double-lockout option pays if the value of the underlying asset remains confined within a specified range.
Look back option
A look back option pays depending on the highest value reached by the underlying during the contract period. Some of the look back options use the highest value reached by the underlying during the contract period to determine the amount of settlement. One formula for the lookback is:
Look back = Maximum (Spot Price at Expiration – Minimum Spot Price over Term of Contract, or 0)
Single-barrier options
Single-barrier options are options which have a single trigger price that is either above or below the strike price whereas double-barrier options have trigger prices that are above and below the strike price. Because the option may either not come into existence or pass out of existence, barrier options are generally cheaper than the standard options but the double-barrier options are the cheapest.
Double-trigger option
A double-trigger option, often used for insurance purposes, pays off when 2 events occur. A company or an insurance company will buy this option to limit losses that are unlikely, and it would be very expensive if they both occur. An example would be if a company had a large property loss in a foreign country due to changes in the foreign exchange rate made the loss much more expensive.
Weather options
Weather options pay off only for unusual weather. Many businesses that are affected by the weather, such as utilities and ski resorts, use these options to keep cash flow more consistent.
Exotic options are frequently used to make the price of options (and hedging) cheaper, by excluding some opportunities for exercise but one must notice to beware as Exotics can be complex, expensive and hard to understand (i.e. involve high gearing).
