Add **Comment, no more than 140 words (optional)An option is a financial derivative instrument that gives the holder the right, but not the obligation, to purchase (a call option) or ** (a put option) on or before a predetermined date (expiration date). The asset can be a commodity, a currency, an index, or another financial instrument. Specifically, options trading has two main roles: the buyer (option holder): the payment of a contract for the purchase of an option, known as the "right", with the right to choose whether or not to exercise its right to purchase or ** an asset before the expiration date. However, if the market is not favourable for the exercise of the option, the buyer may choose not to exercise the right and the loss will be limited to the right paid. Seller (Option Writer or Seller): Receives the premium paid by the buyer and assumes the obligation to fulfill the terms of the contract when the buyer exercises the right. The seller's income is fixed, but if the market** is not in the seller's favor, the seller may have to bear a huge loss. There are two main types of options: Call options: Call options, which give the holder the right to purchase the underlying asset for a specific ** on or before the expiration date. Put Option: Gives the holder the right to take a specific *** underlying asset on or before the expiration date. The value of an option is determined by a number of factors, including but not limited to: underlying asset**, exercise**, remaining term, market volatility, risk-free rate, etc. In addition, options can be divided into European options (exercisable only on the expiration date) and US options (exercised on or at any time before the expiration date). In practice, options are widely used in risk management, investment strategy construction, arbitrage trading and hedging strategies. Options provide investors with a variety of investment opportunities and risks. Details below:

Investors can potentially earn a greater potential return than the principal amount invested, by paying the right** (a relatively small amount). For example, when the underlying asset is ***, buying a call option can earn an excess return. Risk management: Options can help investors hedge their risk. For example, investors who hold ** can hedge the risk of their holdings by buying put options and maintain the value of the asset. Diversified investment strategies: Options trading can construct a variety of investment strategies, such as covered sell strategies, spread trading (including vertical spreads, horizontal spreads, diagonal spreads), butterfly spreads, etc., which can adapt to different market expectations and risk appetite. Market Volatility Utilization: The options market is particularly suitable for investors who are adept at capturing market volatility. In a volatile market, both call and put options can be tools for investors to make gains. 
Add **Comment, no more than 140 words (optional) Risk: Time Value Loss: Options have time value. The value of the option will naturally decrease over time, and unless there is a significant change in the underlying asset**, it will be more than enough to offset the loss in time value. Total loss risk: The maximum loss for the option buyer is limited to the right to purchase the option**, but the investor may lose all of his rights if the option is exercised** or if the market trend is contrary to expectations**. Wrong market judgment: Investing in options depends on the investor's judgment of future market trends. If the judgment is wrong, both call and put options can cause losses. Liquidity risk: Some options contracts may have poor liquidity, resulting in a large gap in sales**, increased transaction costs, and may be difficult to close positions quickly in an emergency. Leverage Counters: While the leverage effect of options provides an opportunity to expand income, it also magnifies potential losses. Especially when selling options, the potential loss can theoretically be unlimited. Complexity risk: Options trading strategies are diverse and complex, and misunderstandings and applications may lead to unexpected losses for investors. Therefore, when trading options, investors should fully understand the operation mechanism of options products, be familiar with market rules, establish appropriate risk management strategies, make full use of the opportunities brought by options, and properly manage risks. 
The specific cost of trading options for investors is made up of a number of factors, and the specific value of each factor will vary depending on different markets, different brokers, and different periods. Here are a few common cost items and general scopes: Entitlement: Entitlement is the main cost when buying an option contract, which is determined by market supply and demand and cannot give a fixed value. For example, in the U.S.** options market, rights to a standard contract (typically representing 100 shares) can range from a few dollars to several thousand dollars. Trading commissions: With fierce competition, many brokers have lowered their trading commissions. In the United States, some brokers, such as Robinhood, offer zero-commission trading, while others may charge fees ranging from $1 to $10 per transaction, or a percentage of the transaction amount. Contract fees: Individual brokers can charge contract fees for options trading, but many have eliminated these fees, especially after the popularity of electronic trading. Clearing fees: Clearing institutions can charge a clearing fee for each trade, usually charged by the broker and included in the commission. Fees are usually small, ranging from a few cents to tens of cents per transaction. Exchange fees: The exchange charges a transaction fee, which is transferred by the broker to the client, and the specific value depends on the exchange and the type of option. Slippage cost: Slippage is a hidden cost caused by non-market ** transactions, which is difficult to give a specific value and depends entirely on market liquidity. Taxes: Fees depend on the jurisdiction in which the investor is located. In the United States, taxes on options trading include, but are not limited to, capital gains tax, which varies depending on the holding period (short-term or long-term) and the level of income. Due to the diversity and real-time changes in the cost of options, investors should carefully read the broker's cost description before trading options, and consult the latest transaction cost standards in real time. At the same time, investors should also consider factors such as futures rights**, market volatility, time value, etc., to fully assess transaction costs.
