What does θ indicate?
In mathematics, the Greek letter theta (θ) is commonly used to represent angles, especially in geometry and trigonometry. This convention dates back to the ancient Greek mathematicians, who used the letter theta (θ) to represent angles in their geometric and astronomical works.

Negative Theta
Theta is negative for long options, meaning that the value of the option decreases as time passes, all else being equal. This is referred to as time decay. So, when you see that an options position has "negative theta," it means that the position will lose value as time passes, all else being equal.
