Futures Knowledge Explains Front Month
In futures markets, front month is the month with nearest expiration date. Suppose in June, futures for Natural Gas are available with expiry in July, August and September. The July contract is front month contract and September contract is the back months contract, because out of all the available contracts, July contract expires first and September contract expires last. The difference in price between the front month futures contract and the back month futures contract is used to calculate the calendar spread.
