Market entrustment is usually to ensure that your order can be closed.

For example, if the current index refers to IF 1205, the contract selling price is 2636.4 and the buying price is 2636.2.

You are bullish and ready to buy.

If you quote at 3636.4, when your bill arrives at the trading system of the exchange, the market pending order may have become the selling price of 2636.6 and the buying price of 2636.4.

So if the price doesn't drop, your order can't be concluded.

But if you order at the market price, your order will be sold at the selling price no matter how much the selling price becomes at this time.

This is the role of market entrustment-to ensure that your order is closed!
