Why is the cost getting lower and lower every time you sell short futures at a profit? Shouldn't short futures be higher and higher?
It's simple. Let me make an analogy. If you short 1 lot at 3000, the cost is 3000 yuan (for the convenience of calculation, 1 lot = 1 yuan). Hearing 2000, you short 1 lot, so you have 2 lots, and the cost is (3000).
