In this method, the profit/loss amount is exchanged at the expiry date. For options which are exercised, profit/loss at the expiry date is determined by the difference between strike price and settlement price at the expiry date.

Daily Settlement Prices

Daily Settlement Price for Futures Contracts

The daily settlement price is calculated as follows at the end of the normal session and rounded to the nearest price tick:

a) The weighted average price of all the trades executed within the last 10 minutes of the normal session,

b) If less than 10 trades were realized in the last 10 minutes of the normal session, the weighted average price of the last 10 trades executed within the normal session,

c) If less than 10 trades were realized in the normal session, the weighted average price of all the trades executed during the normal session,

d) If no trades were realized during the normal session, the settlement price of the previous day will be determined as the daily settlement price.

If the daily settlement price cannot be calculated in accordance with the above methods by the end of the normal session, the settlement price may be determined by using the following methods singly or collectively.

a) The average of the best bid and ask quotations at the end of the normal session,

b) Theoretical prices are calculated considering spot price of the underlying asset or the daily settlement price for other contract months of the contract.

Trade reporting will not be taken into consideration. The right to change the daily settlement price by the Settlement Price Committee is under reserve.

Daily Settlement Price for Single Stock, Index, Mini Index and USDTRY Option Contracts

The daily settlement price is calculated as follows at the end of the normal session and rounded to the nearest price tick:

a) The weighted average price of all the trades executed within the last 10 minutes of the normal session,

c) If less than 10 trades were realized in the normal session, the weighted average price of all the trades executed during the normal session,

d) If no trades were performed, theoretical prices calculated in consideration prices of underlying asset and other contracts based on the same underlying asset will be determined as the daily settlement price.

If the daily settlement price cannot be calculated in accordance with the above methods by the end of the normal session, or it is decided that the prices calculated do not reflect the market correctly, the Exchange may determine the daily settlement price in consideration of theoretical price, the previous day’s settlement price or the best bid and ask prices at the end of the normal session.

Strike Prices

In the case of option contracts, strike prices refer to the prices at which the option holder may buy (for call options) and those at which the option holder may sell (put options).

If the spot price of the underlying security is over TL 8, the option contract is in-the-money, at TL 8, it is at-the-money, and if the price falls below TL 8, the option contract will be out-of-the-money.

Example 2:
