There were many models of domestic RS232 chips to choose from, such as the TNT3232E of Siruipu, SIT3232Eose and RSS232 of Xinlite. These chips complied with the rs-232 standard, supported 3.3V and 5V power supply, had a dual receiver and transmitter, and the communication speed could reach 250Kbit/s. They are suitable for a variety of applications, including battery-powered devices, industrial human-machine interface, laptops, and printer. In addition, domestic chips could replace imported chips and achieve PIN-TO-Pin replacement. The performance parameters were basically the same. However, the information on whether the non-isolated domestic RS232 chip could reach 1 mps was not clear.

Some information about the domestic RS232. It was an interface standard for serial communication, which could connect two computers or other electronic devices. The domestically-made RS232 interface chip has good reliability and programming, and can meet various application requirements. Some domestic companies have launched a series of domestic RS232 products, such as DP3232, TD541S232H, and CH9102. These products have low power consumption, high data rates, and reliability. In addition, there were some domestic substitutes, such as MM32 and GD32. Although the pin definition was compatible with STM32, the underlying structure and register settings might be different. In general, domestic RS232 products were competitive in meeting communication needs and could help customers reduce overall design risks and procurement costs.

There were many options for the robotic trading software. TVCbot was a professional quantitative trading robot software that could automatically send TradingView strategies or indicators to multiple exchanges to place trades. CCR was another digital asset trading software that supported multiple trading strategies, multi-threaded operation, and intelligent tracking. GitHub also had the Win-Many Trading System. It was a stock quantitative robotic trading system that could realize multi-strategy automatic stock selection, automatic position control, automatic completion of trading and other functions. In addition, there were also fast-moving and quantitative DIY-based stock trading robots and other software, which were suitable for small and medium-sized investors and stock players. As for the virtual currency trading platform and the perpetual contract trading robot, the search results did not provide specific software names. Therefore, further investigation and research were needed on the specific choice of the robotic quantitative trading software.

The quantitative research methods could be roughly divided into the following categories: 1. The common quantitative research methods in economics and statistics used the demand and supply of the " supply and demand theory " as the cornerstone of research, and paid attention to the reasonable allocation and adjustment of resources. In art and design related majors, the object of quantitative research was usually the user's needs. There were roughly four directions: weight solution, demand classification, demand transformation, and program evaluation and optimization. However, the direction and use of quantitative research were not limited to these. 2. The specific research methods include the survey method, experiment method, content analysis method, social network analysis method, etc. Among them, the survey method was the most commonly used implementation method in quantitative research, including the design of the survey, sample, data statistics, writing reports, etc. The presentation method in the thesis generally had an independent research method part, and its logical structure was data description-data quality assessment-variable definition-analysis method. 3. Under the quantitative research, a variety of statistics and machine learning algorithms could be used for data analysis, such as narrative statistics, association analysis, regress analysis, and cluster analysis.

Here are some common ways to express the results: ** I. A quantitative expression for uncountable terms ** 1. ** Using a measure word phrase ** - As for the uncountable substance, such as a piece of paper, a glass of water, a bottle of wine, a kilogram of rice, a loaf of bread, a bar of chocolate, and so on. - In this way, a specific measure word was used to express a specific quantity. 2. ** Use adjectives or adverbs to express quantity ** - "much" is used to indicate many uncountable names, such as "There is much water in the river." There is a lot of water in the river." - "Little" means very little, as in "I have a little time." (I barely have time.)" - "A little" means a little, as in "I need a little help." I need some help." - "A lot of/lots of" means a lot, as in "There is a lot of traffic today." The traffic is very heavy today." 3. ** Other ways to express quantity ** - Use a container to express it, such as a cup of tea, a bowl of soup, a bag of rice, and so on. - Words of degree, such as a great deal of, a large amount of, words of scope, such as some, any, and adverbs of degree, such as very, quite, too, enough. ** 2. The quantitative expression of the relevant results of quantitative transactions in the financial field (taking the transaction volume as an example)** 1. It could be directly expressed in terms of a specific amount or number of transactions. For example, the original quantitative transaction might have a transaction volume of 100 billion or 150 billion a day, but after the handling fee was increased, it might only be half of the previous volume. For example, if the previous volume was 100 billion, it might now be around 50 billion. You could also use the handling fee for each transaction (such as increasing the handling fee to 1 yuan per transaction) and the number of transactions (such as less than 20,000 transactions per day) to measure the transaction situation. 2. By comparing the results, such as the volume of the quantitative trading and the volume of the short-term manual trading, the position and influence of the quantitative trading in the market could be expressed. ** 3. The result of a quantitative expression of an abstract concept such as "love"(an indirect quantitative expression)** 1. ** In terms of behavior ** - Observing the number and degree of care, care, support, sacrifice, etc. of one person for another. For example, calculating the number of times a person gave up their own interests for their partner, or the frequency of selfless help when the other party needed it, these behavior data could reflect the quantitative results of love to a certain extent. 2. ** In terms of emotional communication ** - It was measured from the frequency of verbal expression, the frequency of physical contact, the number of shared emotional experiences, and so on. For example, the number of intimate hugs per week and the length of communication per day were counted as part of the quantitative results of love. 3. ** Time investment ** - Calculating the amount of time a person is willing to invest in their loved ones. For example, the amount of time he spent with his partner every month, or the proportion of time he spent participating in the other party's life affairs. 4. ** Quality of life improvement ** - It was measured by the specific indicators of material and spiritual improvement, such as the specific amount of income increase after working together, the quantitative score of the improvement of the living environment (such as the number of square meters of living area increased, the comfort score of the living environment increased, etc.), and the quantitative improvement of cultural accomplishment (such as the increase in the number of books read, etc.). 5. ** In terms of subjective feelings ** - Although it was difficult to directly measure, there were some indirect methods, such as conducting a survey or interview on positive emotions such as happiness, satisfaction, and security. A certain rating standard (such as 1 - 10 points) was used to express the quantitative results of subjective feelings, thus reflecting the quantitative results of love. However, this method was only a reference because love was a complex and multi-dimensional emotional experience.

Quantum funds were investment funds that used mathematics, statistics, and computer algorithms to execute trading decisions. They were also known as quantum or algorithm hedgefunds. It mainly uses mathematical statistics analysis and quantitative investment strategies to carry out investment portfolio management. The goal is to achieve profits through systematic and quantitative methods rather than relying on manual judgment or subjective decision-making. The main characteristics of the quantitative funds included: 1. ** Mathematical and statistics analysis **: Use mathematical models and statistics to identify potential investment opportunities and risks based on historical data, market prices, trading volume, and other factors. 2. ** Arithmetic Trading **: Use a computer algorithm to decide to buy and sell assets based on model signals, reducing the interference of human emotions and subjective judgments. 3. ** High-frequency Trading (Part)**: Some quantitative funds use high-frequency trading strategies to trade in large quantities in a very short period of time and profit from small market price fluctuations. 4. ** Diverse Strategy **: For example, market neutral strategy (not considering the overall market trend), trend tracking strategy (trading according to market trend), etc. 5. ** risk management **: Pay high attention to risk management and use models to monitor and control the risk of investment. 6. ** Highly-technical **: Relying on advanced computer technology and data analysis tools to quickly analyze market data and execute transactions. 7. ** Diverse data sources **: Relying on a large amount of market data, such as historical prices, financial data, news events, etc. to build models and make decisions. The strategies used for quantitative funds included quantitative stock selection, quantitative timing, stock index futures arbitration, commodity futures arbitration, statistics arbitration, option arbitration, algorithm trading, asset allocation, etc. While waiting for the TV series, he could also read the exciting content related to this site!
