The position difference is the increase or decrease of the position on the same day, that is, how much the position of a certain variety today has increased compared with that of the variety yesterday.

Why is there a positive and negative warehouse difference?

1, warehouse difference is zero:

If either of the buyers and sellers is an existing trader, then the "position difference" is zero. Let's take Apple's 190 1 contract as an example. If investor A opened more than one order before Apple Futures 12000, now Apple has risen to 13000. At this time, A wants to hedge his multiple orders, so he chooses to close the position with an empty order. The "warehouse difference" at this time is compared with yesterday's-1. It happens that investor B is optimistic about the future trend of Apple 190 1 contract and wants to open more positions, so the "position difference" is compared with yesterday's+1. Then today's "warehouse difference" overall changes to 0. That is, the warehouse variance is 0.

2. The warehouse variance is negative:

If both buyers and sellers are pre-stored traders and choose to close their positions at the same time, the "position difference" is negative. Similarly, take Apple 190 1 as an example. If investor A opened more than one order before Apple 190 1 contract 12000, investor B has an empty order, but Apple futures have now risen to 13000. A thinks that Apple is more likely to fall in the future and wants to close more orders.

3. The warehouse variance is positive:

If buyers and sellers open positions at the same price, the "price difference" is positive. Take the Apple 1905 futures contract as an example. If Apple 1905 has two investors, A and B, in 12000, A is optimistic about the future trend of Apple 1905, so he chooses to open a position in 12000. And B thinks that Apple futures will fall in the future, so he chooses short positions, so the position of Apple 190 1 today is +2. That is, the position difference is positive.
