The risk of loss in trading options can be substantial. Under certain circumstances, the losses you incur may exceed the initial margin amount deposited. Even if you set contingency orders, such as “stop-loss” or “limit” orders, they may not prevent losses. Market conditions may make it impossible to execute such orders. You may 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. Nevertheless, you will remain responsible for any shortfall in your account resulting from such liquidation. Therefore, before engaging in trading, you should thoroughly 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 associated with exercising options and their expiration.
