In addition to leverage and shorting, futures also have the characteristics of T+0. Everything is not much different from stocks, and the benefits are all in the strength of personal operation. So it is easy to understand that you can ask such a question. Needless to say, if you want to believe. Mainly options. Let's first understand the concept: an option is the right to buy or sell a certain number of specific assets at a specific price at a specific time in the future. Option trading is a kind of right trading. In futures option trading, the option buyer obtains the right to buy or sell a certain number of futures contracts from the option seller at a predetermined price (exercise price) within the time stipulated in the contract after paying a fee (royalty). After receiving the option fee paid by the option buyer, the option seller must unconditionally perform the obligations stipulated by option contracts as long as the option buyer requests to exercise his rights. In futures trading, buyers and sellers have equal rights and obligations. In contrast, the rights and obligations of buyers and sellers in option trading are not equal. After paying the patent fee, the buyer has the right to execute and not to execute, but has no obligation; When the seller receives the royalty, no matter how unfavorable the market situation is, once the buyer proposes to implement it, he is obliged to perform the option contracts, but has no right. Here is a key word: exercise price, exercise or not (in jargon, exercise). During the delivery period (exercise period) stipulated in the contract, if the futures price is compared with the exercise price, you can exercise (exercise) whether you buy a call option or a put option at this time. Get a futures contract that is beneficial to you. At this point, the return is positive. When the futures price runs in the opposite direction to the options you buy, the options yield is huge. When exercising, you can choose not to exercise. At this time, no matter how serious the loss is, because the rights are not in place, that is, the actual futures contract is no longer obtained, and the loss is only the paid royalties. Therefore, it can be considered that option trading is a trading form that locks in losses (determined when purchasing options) and has unlimited gains. Just add that when the futures market is likely to be bullish, the premium of call options will increase accordingly, and vice versa.
