spot and futures prices must change in the same direction, and the quantity is your own control. 1 tons of spot is the 1 lots of soybeans in futures. Because you are hedging, although the spot price may rise in November and the futures price will fall before delivery, the futures price will return to the spot price at the time of final delivery, so the change amount of the two will be almost the same, so the hedging may eventually be total. Either small profit or flat, buying or selling futures contracts with the same quantity and opposite direction in the futures market and selling or buying futures contracts in the future to offset the losses in the spot market is hedging.
