The calculation formula is: profit and loss of the day = (selling price-settlement price of the day) * selling amount+(settlement price of the day-buying price) * final buying amount+(settlement price of the previous trading day-settlement price of the previous trading day) * (selling positions of the previous trading day-buying futures of the previous trading day), futures adopt the margin system, and the margin is generally futures, accounting for10 of the contract value. The contract value is equal to the futures stock index multiplied by the multiplier, so the contract value changes under the influence of the futures stock index and the contract multiplier. Other things being equal, the greater the contract multiplier, the greater the contract value, which means the greater the contract value of stock index futures.

Trading margin of the day = settlement price of the day * total position after trading of the day * trading margin ratio. These two formulas explain how futures companies collect the profit and loss settlement and margin of customers' positions after the day's trading (regardless of the profit and loss of the day's trading when customers open positions and open positions).

Other things being equal, the contract value increases with the increase of the basic index, so does the contract value of futures. When futures and HSI introduce contract value, the contract value but health index is less than 2000 points (contract multiplier is HK$ 50), so the futures contract value does not exceed HK$ 654.38+ million. In 2009, the value of Hang Seng Index contracts exceeded 2000 () points, and the value of Hang Seng Index futures contracts exceeded HK$ 65.438 billion.

1. Calculation of fair value of forward contract?

Therefore, the formula for calculating the fair value of a forward contract is: the balance sheet fair value of a forward contract = (the forward exchange rate agreed in the contract-the forward interest rate of a forward contract with the same delivery date in the financial market on the balance sheet date) × the due delivery date × the discount rate, where (the forward exchange rate agreed in the contract-the forward interest rate of a forward contract with the same delivery date in the financial market on the balance sheet date )× the due delivery amount can be understood as the intrinsic value, and multiplied by the discount rate reflects the time value.

2. What is the understanding of the fair value of forward contracts?

Simply understood, the fair value of a forward contract includes intrinsic value and time value, in which intrinsic value is the difference between the forward contract and the contract amount on the same delivery date in the financial market on the balance sheet date, and time value is the discounted value.

3. How to calculate the fair value of forward contracts?

Suppose that the forward contract you bought and held on the balance sheet date has the same transaction direction, amount, quantity and maturity date, and compare this price with the forward contract price you held on the purchase date to confirm the change of fair value. Of course, the price generally needs to be asked by the bank!

4. What is the difference between the price and value of a forward contract, and how is its value determined?

This is a standardized forward contract. The delivery time of the forward contract is agreed by both parties, while the delivery time of the forward contract is stipulated by the exchange. The amount of forward contract transactions shall be agreed by both parties, and the amount shall be traded in the unit specified by the exchange. For example, Party A and Party B agreed that after 100 days, Company A would buy 100 tons of copper from Company B at a price of 53,000 tons. This agreement is a long-term contract, which is reached by both parties through negotiation. In this case, the delivery time and price are set and standardized by the exchange. For example, a company buys 100 tons of copper in the market, but the delivery time is not necessarily exactly 100 days later, and the price is not necessarily 53,000/ton. Everything depends on the exchange.
