What is options Delta and how does it affect price?

- Delta = ($1.80) / ($3)
- Delta = +0.6

What is a good delta to theta ratio?
Basically, for a non-directional trader capitalizing on theta decay, you want to try to target a 0.5 delta-to-theta ratio. Keep delta at 50% or less of your theta, and you should be good. This ratio may not always be possible when the price moves all around in the middle of a trade. It also depends on the underlying.

If an options delta is less than 50 it is said to be out of the-money. If the delta is greater than 50 the option is said to be in-the-money.
Can option delta be higher than 1?
Call Option Delta A call option's value increases when the underlying price goes up. Therefore, it makes sense that call delta is always a non-negative number. At the same time, a call option's value can't grow faster than underlying price. As a result, call delta can never be greater than 1.
Are delta options accurate?

Call Option Deltas vs. Put Option Deltas
Call Option Price vs. Stock Price Changes
So, you know the basics of what delta represents, but now it’s time to learn about the differences between call and put deltas. As you may have noticed in the table from the last section, the call deltas are positive, and the put deltas are negative. More specifically:
Put Option Price vs. Stock Price Changes
As an illustration, we analyzed the price changes of a call option traded on SPY. Here are the specifics:
Using Delta to Measure Directional Risk
In this example, we’ll visualize the price changes of the March 200 put on SPY.
Visualizing Call Option Price Sensitivity
Now, it’s time to learn about how an option’s delta value represents its price sensitivity relative to movements in the stock price.
Visualizing Put Option Price Sensitivity
To visualize the price changes of SPY call options with different deltas, we analyzed three separate call options with deltas of +0.25, +0.50, and +0.75, respectively. When examining this visual, notice how each option’s delta translates to its degree of price sensitivity:
Option Strike Price vs. Delta
To analyze put option price sensitivity based on the option’s delta, we’ll use the same stock, time period, and expiration cycle as before. However, we’ll analyze three separate SPY put options with deltas of -0.25, -0.50, and -0.75, respectively.
