FX Options: What are the option greeks and how can I see them in the platform?

What are the "Greeks”?

  • Delta: Shows the equivalent FX Spot exposure of a given position. This is the sensitivity of a position’s value with respect to the spot rate.
  • Gamma: This is the second derivative of the position value with respect to spot, i.e. it shows how much the delta changes when spot changes (i.e. how much will the delta change when spot moves up by one percentage point.
  • Vega: Sensitivity of a position with respect to the implied volatility used to price FX Options. This shows how much money is made (positive number) or lost (negative number) when volatility goes up by one percentage point.  
  • Theta: Also known as time decay. This shows by how much the position will increase or decrease in value from one day to the next.
