An option gives a person the right but not the obligation to buy or sell something. An option is a contract between two parties wherein the buyer receives a privilege for which he pays a fee (premium) and the seller accepts an obligation for which he receives a fee. The premium is the price negotiated and set when the option is bought or sold. A person who buys an option is said to belong in the option. A person who sells (or writes) an option is said to be short in the option.

The Exchange, at its discretion, may enable additional strikes as specified in the direction of the price movement, intraday, if required. The additional strikes may be enabled during the day at regular intervals and message for the same shall be broadcast to all trading terminals.

Price steps

The price step in respect of the options contracts is Re.0.05.

Base Prices

The base price of the options contracts, on the introduction of new contracts, would be the theoretical value of the options contract arrived at based on the Black-Scholes model of calculation of options premiums or the settlement price as computed by Clearing Corporation.

The options price for a Call, computed as per the following Black Scholes formula:
C = S * N (d1) - X * e- rt * N (d2)

and the price for a Put is : P = X * e- rt * N (-d2) - S * N (-d1)

where :
d1 = [ln (S / X) + (r + σ2 / 2) * t] / σ * sqrt(t)
d2 = [ln (S / X) + (r - σ2 / 2) * t] / σ * sqrt(t)
= d1 - σ * sqrt(t)

C = price of a call option
P = price of a put option
S = price of the underlying asset
X = Strike price of the option
r = rate of interest
t = time to expiration
σ = volatility of the underlying

N represents a standard normal distribution with mean = 0 and standard deviation = 1
ln represents the natural logarithm of a number. Natural logarithms are based on the constant e (2.71828182845904).

The rate of interest may be the relevant MIBOR rate or such other rate as may be specified.

The base price of the contracts on subsequent trading days will be the daily settlement price of the options contract as computed by Clearing Corporation.
