Risk Warning
An option is a contract that gives the holder the right, but not the obligation, to buy or sell an asset at a fixed price at any time on or before a specific date. The price of an option is influenced by several factors including the current price of the underlying asset, the strike price, time to expiration, and implied volatility.
Implied volatility reflects the market’s expectation of the future volatility of an option over a certain period. It is data derived inversely from the BS option pricing model and is generally considered an indicator of market sentiment. When investors anticipate higher volatility, they may be willing to pay more for options to hedge risks, resulting in higher implied volatility.
Traders and investors use implied volatility to assessoption pricesthe attractiveness, identify potential mispricing, and manage risk exposure.

This content does not constitute any offer, solicitation, recommendation, opinion, or guarantee for any securities, financial products, or tools. The risk of loss in trading options can be substantial. In some cases, losses may exceed the initial margin deposited. Even if you set contingent orders such as 'stop-loss' or 'limit' orders, these may not prevent losses. Market conditions may prevent these orders from being executed. You might be required to deposit additional margin within a short period. If you fail to provide the required amount within the specified time, your open positions may be liquidated. However, you will still be responsible for any shortfall in your account. Therefore, before trading, you should study and understand options and carefully consider whether such trading is suitable for you based on your financial situation and investment objectives. If you trade options, you should be familiar with the procedures for exercising options and the rights and obligations upon exercise and expiration. Option trading involves extremely high risks and is not suitable for all investors. Investors should read carefully before engaging in any options trading strategy.Characteristics and Risks of Standardized Options。
