In the futures market, some people analyze the price trend through the number of large positions. Those who follow large households will operate according to the positions held by large households. For example, comparing the number of positions held by the top 20 multi-single large households with the number of positions held by the top 20 empty single large households shows that there are net multi-single and empty orders, indicating that the concentration of holding multi-single in large households is higher than that of holding empty orders.

For qfii, you can't hold empty orders but there is no spot to hedge.
