Basic knowledge of options, first bullet
Starting today, I will popularize the basic knowledge of options trading. Major exchanges should thank me for providing free investment education, haha.
Let's talk about the four trading directions of options first.
Options, options, a right to buy or sell spot at a specific price at a future time.
Therefore, options are divided into call options and put options.
Call, call option, stipulates that the buyer of the option buys spot at a specific price at a specific time in the future.
Call options include two trading directions:
Long call, buy call
Short call, sell call
Put, put option, stipulates that the buyer of the option sells spot at a specific price at a specific time in the future.
Put options include two trading directions:
Long put, buy put
Short put, sell put
For example,
Ethereum Long- 20240419- 3600-call
The above option means that the eth call option expires on April 19, 2024, with an exercise price of $3,600.
If you buy this option and choose to exercise it when it expires, you can buy the aunt at a price of $3,600. If it rises to $3,700 at this time, you will make a profit. If it falls to $3,500 at this time, it is not profitable, and you can also not exercise the option, and only lose the premium for buying the option.
If you sell this option, you promise to sell the aunt at a price of 3,600 yuan as agreed when the option expires. No matter how much the aunt price is at that time, as long as someone exercises the option with you, you must fulfill the contract. In return, you can get the option premium.
So, the buyer pays the premium and gets a promise. The seller promises a promise, gets the premium, and the option transaction is completed.
In order to ensure fulfillment, we will also ask the seller to pay a certain margin.
In reality, many buyers use option leverage to bet on unilateral rises and falls for the sake of safety and risk-taking. Many sellers do it to hedge spot risks and hedge arbitrage.
Everyone gets what they need and gets what they want. This is the charm of the financial market.
At present, Bitcoin and Ethereum options are relatively mature, and everyone can trade together.
Next time, we will talk about the impact of Greek letters on trading.
