non-commercial transactions are speculative transactions. let's say you buy an oil contract, but you do not have a business with oil, there will be no physical delivery, you will sell it when it comes to the price you want. this purchase you make is called speculative purchase. the same goes for the sales situation. what you buy and sell does not have to be emitia, oil is an example.
