根据前期对金融市场投资系统的移动端使用情境特点的分析，移动端的使用环境

According to the previous analysis of the characteristics of the mobile terminal usage scenarios of the financial market investment system, the uncertainty of the mobile terminal's use environment often results in users who can only operate on the mobile terminal during fragmented time. In addition, according to the observations of investment managers using the PC terminal in field observations, users have clear goals when using the financial market investment system, such as viewing overall data, querying specific project/fund information, paying attention to work to-dos, and viewing new news. Combined with the investigation of the investment management platform, it is concluded that the security principles, consistency principles, operational flexibility principles, feedback effectiveness principles and brand communication principles applicable to the mobile terminal design of the financial market investment system are summarized as follows: <br>Security It is the primary foundation for the investment management system to go online. According to the results of the Deloitte Global Risk Management Survey, many investment management companies may need to modernize risk management. 60% of the investment management companies surveyed believe that cybersecurity is one of the three major risk management challenges.

Nielsen pointed out that the same terms, functions, and operations in the software page should be consistent. In the same language and context, the same operation should have the same result. Applying the principle of consistent design in the investment management system can help users quickly familiarize themselves with and locate their target information in the same type of page. The following describes how to grasp the consistency of the mobile terminal of the investment management system from three aspects. First of all, you need to meet The business layer and the logic layer, followed by the framework layer and the structure layer, and finally the interaction and interface presentation layer.

According to the analysis of the situational characteristics of mobile use of financial market investment system in the early stage, the uncertainty of the use environment of the mobile side often leads to the user's operation of the mobile side only at the time of fragmentation. In addition, according to the field observation of the investment manager using the PC side of the observation, users in the use of financial market investment system have clear objectives, such as looking at the overall data, query specific project/fund information, pay attention to work to-do list, view new news and so on. Combined with the research on the investment management platform, this paper summarizes the security principles, consistency principles, operational flexibility principles, feedback effectiveness principles and brand communication principles applicable to the mobile design of financial market investment systems, which are described as follows:<br>Security is the primary basis for investment management systems to operate online. According to Deloitte's global risk management survey, many investment management companies may need to modernize their risk management, with 60 percent of investment managers surveyed citing cybersecurity as one of the three main challenges to risk management, and the U.S. Securities and Exchange Commission and European financial regulators focusing on cybersecurity.<br>The principle of consistency stems from Nielsen's top ten usability principles, and Nielsen points out that the same language, function, and operation should be consistent on software pages, and that the same actions should result in the same results in the same language and context. Applying the principle of consistency design in investment management system can help users to quickly familiarize themselves with and locate their target information in the same type of page, the following three aspects explain how to grasp the consistency of the mobile side of the investment management system, first need to meet the business layer and logical layer, followed by the framework layer and structure layer, and finally the interaction and interface performance layer.

According to the previous analysis of the characteristics of the use situation of the mobile terminal in the financial market investment system, the uncertainty of the use environment of the mobile terminal leads to that users can only operate on the mobile terminal in the fragmented time. In addition, according to the observation of investment managers using PC in the field observation, users have clear goals when using the financial market investment system, such as viewing the overall data, querying specific project / fund information, paying attention to work to do items, viewing new news, etc. Based on the investigation of investment management platform, this paper summarizes the principles of security, consistency, operation flexibility, feedback effectiveness and brand communication, which are applicable to the design of mobile terminal of financial market investment system<br>Security is the primary basis for the investment management system to run online.

Nielsen points out that the same language, function and operation in software pages should be consistent, and the same operation should produce the same results in the same language and situation. The application of consistency design principle in the investment management system can help users quickly get familiar with and locate their target information in the same type of pages. The following three aspects describe how to grasp the consistency of the mobile end of the investment management system. First, it needs to meet the business layer and logic layer, then the framework layer and structure layer, and finally the interaction and interface presentation layer.<br>
