1. Trading definition

refers to the option that both parties have on whether to buy or sell a certain foreign exchange in the future according to the agreed exchange rate in the process of foreign exchange trading

2. Trading advantages
option trading makes up for the defect that forward trading only guarantees present value but not future value. It has greater flexibility, and for contract holders, when the exchange rate is favorable, they will take non delivery measures, so that the exchange rate risk loss is less than or equal to the insurance premium
(1) option is an effective risk management tool. Options are futures contracts, which can be said to be derivatives of derivatives. Therefore, options can be used to maintain the value of both spot and futures business. Through the call option, it can keep the value of the spot or futures, and will not face the risk of margin call. Through the put option, we can rece the cost of holding or increase the position income. The comprehensive use of options with different strike prices and different maturities makes it possible to provide tailor-made hedging strategies for hedgers with different preferences
(2) options provide investors with more investment opportunities and strategies. In futures trading, only when the price changes directionally can the market have investment opportunities. If the price is in the consolidation period with less fluctuation, there will be no investment opportunities in the market. In option trading, whether the futures price is in bull market, bear market or consolidation, it can provide investors with profit opportunities. Futures trading can only be based on direction. The trading strategy of options can be based on the change direction of futures price, and can also be based on the volatility of futures price. When investors are bullish on volatility, they can buy straddle, wide straddle and other trading portfolios; On the contrary, if investors are short of volatility, they can do the opposite of the above strategy< (3) leverage. Options can provide investors with greater leverage. In particular, the short maturity of the virtual option. Compared with futures margin, the same amount of contracts can be controlled with less royalty. Take the average option as an example to compare with futures< (1) unique profit and loss structure

compared with stock, futures and other investment tools, the difference of option lies in its nonlinear profit and loss structure
for a long futures position with a cost of 1800 yuan / ton, the position loss will increase by one yuan for every one yuan rise in price and one yuan fall in price. For short futures positions, the opposite is true
profit and loss 1800 the profit and loss chart of futures price futures position is the profit and loss chart of long call option with execution price of 1800 yuan. The profit and loss chart at maturity is a broken line rather than a straight line, and there is a corner at the position of the execution price. If the futures price is less than the option strike price, the call option is in a state of virtual value and has no value at maturity. No matter how deep the futures price falls, the buyer's loss will not increase; If the maturity futures price is 1820 yuan, the call right is in the state of profit and loss balance; If the futures price is greater than the option strike price, the nature of call option long position is the same as that of futures long position, and the relationship between the profit and loss of call option and the change of futures price begins to change in the same direction
it is the nonlinear profit and loss structure of options that makes options have obvious advantages in risk management and portfolio investment. Through the combination of different options, options and other investment tools, investors can construct different risk return portfolio
(2) the risk of option trading
in option trading, the rights and obligations of the buyer and the seller are different, which makes the buyer and the seller face different risk situations. For option traders, both the buyer's and the seller's positions are faced with the risk of adverse changes in royalty. This is the same as futures, that is, within the range of royalty, if you buy low but sell high, you can make a profit by closing the position. On the contrary, it will lose money. Different from futures, the risk bottom line of option bulls has been determined and paid, and its risk is controlled within the scope of royalty. The risk of option short position is the same as that of futures position. Because the premium received by the option seller can provide corresponding guarantee, it can offset part of the loss of the option seller when the price changes unfavourably
although the risk of the option buyer is limited, the proportion of its loss may be 100%, and the limited losses add up to a larger loss. The option seller can receive the premium. Once the price has a big adverse change or the volatility rises sharply, although the futures price can not fall to zero or rise indefinitely, from the perspective of capital management, for many traders, the loss at this time is equivalent to "infinite". Therefore, before making option investment, investors must have a comprehensive and objective understanding of the risk of option trading.
