Introduction
Options trading can be a great way to make money, but it can also be risky. One of the most important things to understand when trading options is the concept of delta. Delta measures the sensitivity of an option’s price to changes in the underlying asset’s price. It is a key factor in determining the risk and reward of an options trade.

In this article, we will explain what delta is, how to calculate it, and how to use it to make better options trades.
What is Delta in Options Trading?
Delta is a Greek letter that measures the rate of change of an option’s price in relation to the price of the underlying asset. It is expressed as a number between -1 and +1.
A delta of +1 means that the option’s price will increase by $1 for every $1 increase in the underlying asset’s price. A delta of -1 means that the option’s price will decrease by $1 for every $1 decrease in the underlying asset’s price. A delta of 0 means that the option’s price will not change in response to changes in the underlying asset’s price.
How to Calculate Delta
Delta can be calculated using the following formula:
Delta = (Change in option price) / (Change in underlying asset price)
For example, if an option’s price increases by $0.50 for every $1 increase in the underlying asset’s price, then the delta of the option is 0.5.
How to Use Delta in Options Trading
Delta can be used to make more informed options trades. By understanding the delta of an option, you can better assess the risk and reward of the trade.
- If you are buying an option, you want to choose an option with a delta that is close to 1. This will give you the most leverage and the greatest potential for profit.
- If you are selling an option, you want to choose an option with a delta that is close to 0. This will reduce your risk and limit your potential losses.
