Forex Options Trading - How Forex Options Are Calculated (Part 1 of 2)

Forex options are calculated with 'Greeks'. A basic explanation of these 'Greeks' will help you understand how and why the forex options move and behave in a certain way. An option is a derivative and how it's value is derived is from a formula that combines these Greeks together. The Greeks are how these options respond to various factors such as price movement, time decay, volatility, and interest rates.

There are 5 Greeks involved and we share go through them one by one.

Delta:
The speed of the option's price gain or loss against the gain or loss of the 'mother' or underlying asset price is known as the Delta. The Delta is a figure that shows us how fast or slow the option will move relative to its 'mother' or underlying asset. A Delta of 1 means the option price is moving at the same speed and direction as the 'mother' or underlying asset. A Delta of -1 means the option price is moving in the opposite direction for every point the 'mother' or underlying asset moves.

The probability of an option expiring in-the-money is also expressed in the Delta. An at the money call option has a Delta of 0.5; i.e., 50%, meaning a 50% chance of expiring in the money. A deep in the money call will have a Delta of near 1, or 100%, meaning a near 100% chance of expiration in the money. A very out-of-the-money call option will have a Delta of close to zero, meaning a near zero chance of expiring in the money.
