If you're wondering what 'Greeks' are, they are defined to be the way options normally respond to various factors that govern Forex, such as price fluctuations, time decay, market volatility, and different interest rates.
One such Forex option formula is the Delta. It is described to be the speed with which an option rises or decreases in price as against the underlying price of the currency it has been bought on. A Gamma is a 'Greek' formula derived from the Delta, and describes the odds of any changes that may occur in Delta. A Gamma also serves as an advance warning of any indications of change in the Delta. Gammas are considered positive signals for both a call and put option, and most traders tend to keep an eye on Gamma formulas closely.
A Theta signifies time decay. Options have a prescription period, and as the time of its expiration nears, the value of the Theta approaches zero to negative. If the Theta has a positive number, it means that there is still enough time for a trader to exercise the option. A Vega, on the other hand, reflects how the volatile market affects the option's price. You may notice that an option's price increases depending on how the market's volatility affects the underlying asset. Volatility is a good thing if you are a buyer of an option, but a bad thing if you are about to sell one.
Finally, a Rho describes how the option is affected by the prevailing interest rates. A positive Rho defines high interest rates that are good for the option, and are negative if high interest rates are bad for it.
