What is a 'Currency Option'
Currency options are one of the most common ways for corporations, individuals or financial institutions to hedge against adverse movements in exchange rates.
Investors can hedge against foreign currency risk by purchasing a currency put or call. Call options provide the holder the right but not the obligation to purchase an underlying asset at a specified price the strike price , for a certain period of time. If the stock fails to meet the strike price before the expiration date, the option expires and becomes worthless. Investors buy calls when they think the share price of the underlying security will rise or sell a call if they think it will fall.
Selling an option is also referred to as ''writing'' an option. Put options give the holder the right to sell an underlying asset at a specified price the strike price. The seller or writer of the put option is obligated to buy the stock at the strike price. Put options can be exercised at any time before the option expires. Investors buy puts if they think the share price of the underlying stock will fall, or sell one if they think it will rise.
Put buyers - those who hold a "long" - put are either speculative buyers looking for leverage or "insurance" buyers who want to protect their long positions in a stock for the period of time covered by the option. Put sellers hold a "short" expecting the market to move upward or at least stay stable A worst-case scenario for a put seller is a downward market turn.
The maximum profit is limited to the put premium received and is achieved when the price of the underlying is at or above the option's strike price at expiration.
The maximum loss is unlimited for an uncovered put writer. Options pricing has several components. At the expiration date of the option, which is sometimes referred to as the maturity date, the strike price is compared to the then-current spot rate. Depending on the type of option and where the spot rate is trading, in relation to the strike, the option is exercised or expires worthless.
If the option expires in the money, the currency option is cash settled. I present you with my restructured project on options trading and scenario analysis. You are more than welcome to try it out. Firstly, I will give a small presentation that will reveal what you can do with it and whether you need to continue reading.
Then I will continue with dependencies, classes used and classes created along with methods defined. Finally, I will give some basic operations to show how you can use it yourself. Lets say you are constructing a portfolio. You want to start with risk-reversal strategy buy call high, sell put low.
You are interested in payoff chart: For some reason you decide to short a stock and add it to your portfolio: You now realise that you must really have negative view on the market to trade this.
You decide that this will be your view, but your neighbour tells you that a sharp price increase is possible. Decide to buy some digitals: You are satisfied with your decisions and would like to check you profit and loss as up to now numbers on z axis just showed payoff. But your digitals cost and sum of option prices should be slightly positive as both symmetrically out of the money: While you are very happy with your decisions you also want to investigate some sensitivities.
If you liked what you saw and you want to try it yourself or even contribute, continue reading. It has only 1 line to call all you need: And by all I mean 2 things: File structure is simple: Surprisingly only lines of code. Went down twice after I drifted to OOP approach. Classes used are S4 for outputs, some simple variables that needed formalisation and parameter objects.
Reference classes are used for instruments. Contains output from reference classes: All of them have same methods: All of them have arguments:
In FX options, the asset in question is also money, denominated in another currency. For example, a call option on oil allows the investor to buy oil at a given price and date. The investor on the other side of the trade is in effect selling a put option on the currency. Selling an option is also referred to as ''writing'' an option. Put options give the holder the right to sell an underlying asset at a specified price (the strike price). The seller (or writer) of the put option is obligated to buy the stock at the strike price. FX futures and options offer investors a direct way to profit from changing exchange rates, letting them make both pro-dollar and anti-dollar bets with relative ease.
