In stock trading, being long a stock means an action to buy a stock while being short a stock means borrowing and selling a stock which you dont own. In futures trading, the Long refers to the PERSON in a futures transaction that is committed to buying the underlying asset from the person known as the Short. So long and short in futures trading refers to the parties rather than a transaction type or order type. For example, A who thinks price will decrease is entering into obligation to sell shares we say A is going SHORT in future. While B who thinks price will Increase is entering into obligation to buy shares, we say B is going LONG in future.
