Why choose top 1, top 2 and other major firms when making contracts? Leaving aside the fact that large institutions have strong financial resources and value reputation, the key is liquidity; In fact, currently all exchange contracts are bet against clients, but the number of long and short positions made by the exchange at the same time is almost the same, so clients bet against each other. The exposure of the exchange is very small, so even if you win money, you win the client's money, and the exchange steadily incurs transaction fees; Although the small office also earns transaction fees, most of them are returned to KOLs (code stackers). Therefore, the contracts of the small office are mainly based on customer losses, all of which are bets. The trading robots closely monitor the prices of the large office and feed customers to complete transactions. Due to the lack of liquidity, it is easy for most customers to go in the right direction. Therefore, the exposure of the exchange is too large. If customers win money, it means they win money from the exchange. If you win too much, you need to provide proof of income since birth; Of course, some small firms may sell orders, and when the exposure is too large, they go to large firms to hedge. Although they control the risk, they also lose profits that should be eaten but not eaten!
