b) If less than 10 trades were realized in the last 10 minutes of the session, the weighted average price of the last 10 trades executed during the session,
c) If less than 10 trades were realized in the session, the weighted average price of all the trades executed during the session,
d) If no trades were done during the 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 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.
