Why is the daily settlement determined by the futures trading system? Futures implement T+0, two-way trading system and margin system. The margin system determines that futures have poor anti-risk ability and can only bear the market price fluctuation of 10%. On the other hand, two-way trading and T+0 system determine that participants' transactions are hedging transactions and can be closed at any time, that is, your profits and losses come from the losses and profits of other traders. Where will the money come from if it is not settled daily? Exchanges and futures companies will not increase your losses or profits.

Delivery is because the origin of futures is spot, and the fluctuation of the market must depend on spot and be consistent with spot. Delivery determines that the price of futures cannot be outside the spot price range.
