Delta in Options Trading: An Overview

Delta in Options Trading: An Overview of the most familiar Greeks, delta is a measure of an option’s sensitivity to shifts in the price of its underlying asset. It shows how much an option’s price will change for every $1 move in the underlying.

Traders often view delta as the probability that an option will end up in-the-money at expiration. For example, a call option with a strike price close to the market’s stock price has a Delta of.50, which translates to a 50% chance of being in-the-money at expiration. Delta also varies depending on how deep in-the-money a trade is and changes in implied volatility.

When you create spreads, calculating the Delta value of each leg is a good way to understand the overall exposure of your positions. Delta values can also help you determine whether you have a profit potential and when to take your profits or cut losses.
