Spot premium means that the spot price is higher than the futures price, and futures premium means that the futures price is higher than the spot price.

In futures, a position has two meanings: 1. Capital and 2. Hold a position (actually a form of capital).

For example, someone said, "My position is a little tight recently, so I need to open less positions."

Or: "His positions are all empty, and now even two daily limit boards can lose a lot!"
