What is quantitative currency speculation
A: using quantitative trading tools and introcing advanced mathematical quantitative models instead of human subjective judgment
currency speculation is not a new term. At the beginning, currency speculation refers to currency speculation. We use a foreign currency to go to the bank's foreign exchange trading center to buy foreign currency according to the price at that time, and then wait for the time when the exchange rate rises to sell foreign currency to earn the price difference
2. We need to understand some mathematical models, such as statistical analysis, artificial intelligence algorithm and so on. Its essence is to use mathematical models to analyze the potential laws of data, find trading opportunities, and use computer programs to search for trading opportunities and complete automatic trading. There is no ready-made software to do this, because it needs to build a professional platform, which is not a person can complete
there are some domestic software, such as great wisdom, which provides quantitative analysis, and some software which provides programmed trading of stocks and futures. But in fact, this is not a real quantitative transaction. In fact, it is very difficult to make a pure quantitative investment software suitable for indivial investors, because the quantitative strategy does not have the established and inevitable law like the traditional fundamentals and technology. He needs to cross multi-disciplinary, multi field to mine the rules of data, and then use the rules to trade. However, the potential laws of different time and space data are not consistent, so it is difficult to standardize the quantitative process
if you are a computer or math professional, you can consider using C, C + +, SQL and other languages, and other software such as MATLAB / SAS. No matter what kind of software, to achieve quantitative trading, it must need a certain modeling basis and programming basis, among which the most important thing is mathematical ability.

3. SPD is the abbreviation of serial presence detect, which means serial detection of the existence of mole in Chinese. That is to check the information of the mole in the EEPROM heap memory slot of IIC serial interface. In this way, the information about the mole must be recorded in the EEPROM. Habitually, we call this EEPROM IC SPD. Abbreviated for serial presence detect, it is a code burned in EEPROM. In the past, BIOS had to detect memory when it was booted, but with SPD, it did not need to detect any more. Instead, BIOS directly read SPD to obtain relevant data of memory
SPD is a set of configuration information about memory moles, such as p-bank number, voltage, row address / column address number, bit width, various main operation sequences (such as Cl, tRCD, Trp, TRAS, etc.)... They are stored in a 256 byte EEPROM (electrically erasable programmable read only memory)
in fact, in SPD, the standard information specified by JEDEC only uses 128 bytes (there are 128 bytes, belonging to the manufacturer's own special area). Generally, a byte corresponds to at least one parameter, and some parameters need to be expressed in multiple bytes (such as proct continuation number, manufacturer's code in JEDEC organization)
each bit in a byte may be used to represent the specific value of this parameter. Because SPD has a lot of information, it will not be listed here one by one. Interested readers can refer to the relevant documents
the timing information in SPD is written to EEPROM by the mole manufacturer according to the characteristics of the memory chip used, and the main purpose is to assist Beiqiao chip to accurately adjust the physical / timing parameters of the memory, so as to achieve the best use effect. If the memory setting option is set to "by SPD" in BIOS
then, when starting up, Beiqiao will automatically configure the corresponding memory timing and control registers according to the parameter information in SPD, so as to avoid the failure caused by manual adjustment errors. Of course, for DIYer, the timing and control parameters can also be adjusted freely (the physical parameters still need to be determined by SPD or North Bridge's own detection)
refresh of SPD
like BIOS on motherboard, SPD can also be refreshed. You can do it with Thaiphoon burner
when the system is unstable e to the insertion of new and old memory with the same size on the motherboard, and the BIOS of the motherboard can't adjust the frequency of the two memory separately, you can brush the weak SPD to the strong memory to improve the stability
note: never brush SPDs with different memory sizes! DDR, DDR2, DDR3 SPD can not be mixed brush. As with BIOS refresh, there are risks. If necessary, please back up the memory SPD before refresh.
