Counterparty price refers to the price of active transaction, and the counterparty price of option refers to the price of entrusted transaction that submits option. The selling price submitted by the buyer is the same as the price listed in the selling order, and the buying price submitted by the seller is the same as the price of the existing pending order on the bill. For example, the opponent's price to buy can be to sell one, and the opponent's price to sell is to buy one.

Second, the counterparty of the option.

To put it simply, when placing an order, the option holder is ready to enter the market and adopt "buy and open positions", referred to as "buy and open positions". If you are ready to leave after holding for a period of time, you will use "sell and close your position", which is referred to as selling flat.

Option obligor, when placing an order, adopts "selling and opening a position", which is referred to as selling. After holding it for a period of time, prepare to leave the market and take "buy and close the position", referred to as "buy flat".

Buying and selling are opposites, and the counterparty of buying must be selling. But it is not necessarily selling or opening a position. But as long as it is on sale, you can eat all the bills.

Option refers to a contract, which originated in the American and European markets in the late18th century. This kind of contract gives the holder the right to buy or sell assets at a fixed price on or before a certain date. The key points of option definition are as follows:

1. Option is a right. An option contract includes at least a buyer and a seller. The holder enjoys rights, but does not assume corresponding obligations.

2. The object of the option. The subject matter of an option refers to the assets you choose to buy or sell. Including stocks, national debt, currency, stock index, commodity futures and so on. Options are derived from these subject matter, so they are called derivative financial instruments. It is worth noting that the option seller does not necessarily own the underlying assets. Options can be "short". Option buyers may not really want to buy the underlying asset. Therefore, when the option expires, both parties do not have to make physical delivery of the subject matter, but only need to make up the price according to the price difference.

3. Due date. The expiration date of the option agreed by both parties is called "expiration date", and if the option can only be executed on the expiration date, it is called European option; If an option can be exercised at any time on or before the expiration date, it is called an American option.

4. Execution of options. The act of buying and selling the underlying assets according to the option contract is called "execution". The fixed price agreed in the option contract for the option holder to buy and sell the underlying assets is called the "exercise price".
