Methanol futures: Why does methanol futures have two futures codes, Ma and me?
The content of methanol standard contract will change:
From the current 50 tons per hand to 10 tons per hand. The code was changed from me to Ma, and the new methanol contract rules were used from the 1506 contract. The contract before 1506 was mine, 50 tons/lot; 1506 and later are horses, 10t/ hand.
