The "IG Index GME" is the reference index of the Italian Natural Gas Market. It is calculated by GME - at the end of the trading sessions - for each gas day as the arithmetic average of the prices of trades concluded in the 17:15–17:30 time band (including endpoints) in the continuous-trading Day-Ahead Gas Market (MGP-GAS) and in respect of Day-Ahead and WE products.
