Daily Settlement Price
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 during 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 session,
d) If no trades were done during the normal session, theoretical prices calculated, considering 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 with the above methods by the end of the normal session, or the prices calculated do not reflect the market correctly, the Exchange may determine the daily settlement price in consideration of theoretical price, spot price of the underlying asset, the previous day’s settlement price or the best bid and ask prices at the end of the session.
Trade reporting will not be taken into consideration in the above calculations. The Settlement Price Committee’s right to change the daily settlement price is under reserve.
