The most commonly used electronic transactions are online transactions and popular self-service entrustment transactions. Compared with written instructions, electronic trading has the advantages of fast trading speed, quick return and high accuracy, because it directly sends trading instructions to the exchange host, eliminating the intermediate link that must be manually transmitted. These advantages are very important for traders. It is an indispensable condition for those traders who are mainly engaged in short-term trading. However, online trading faces not only the risks of stock index options themselves, but also the risks brought by computer networks. First, security risks When trading online, you must enter your own account number and password. Once your account number and password are known to malicious people, you may illegally enter the transaction, which is likely to bring you huge losses. There was once a case where a criminal posted on a futures forum to induce others to download and install his own program "Futures Wizard", thus stealing several people's trading accounts and passwords, and then using these accounts and passwords to make profits for himself by knocking at the door, causing others to lose 3 1.7 million yuan. This reminds us not to download software that doesn't know the truth easily, so as not to give computer hackers an opportunity. Another way is to change the password frequently to ensure that it will not be known by others. Second, the risk of information loss or failure to trade in time. Online trading is easy to encounter special circumstances such as computer crash and disconnection, which leads to untimely trading of stock index futures and inevitable losses. Therefore, when trading stock index options online, there must be a set of emergency plans, that is, once the computer, telephone and network connection have temporary faults, it is impossible to trade. We should remember the emergency hotline provided by the futures brokerage company. In case of the above situation, you can inquire about the market or issue trading instructions through this phone.
