Today, suppose there is a big, stupid institutional Investor (mutual funds, banks, retirement funds ...). , he wants to buy a stock, but does not want to put the market price to buy, so in the market to hang a big order to buy. At this time all the people in the market will see the limit order book inside someone hung into a big single ready to buy this stock.Suppose the original order book of the market is 200 | $1.01 x $1.03 | 200, and then suddenly this stupid institutional investor comes in

Method Sharing: Let's take a look at the original artwork and the effect comparison: Forgive me what I do here is not very fine ha, this is also a piece of material on the internet can often see pictures: First we copy the original Layer two layers: Then the layer 1 Gaussian blur, the d

Tags: des style blog color using OS IO dataDeadlocks are not unfamiliar to DBAs or database developers, and they can be triggered in a variety of ways, and in general, developers of database applications are designed with some considerations in mind to avoid deadlocks. But sometimes because of some special application scenarios such as high-frequency queries, highly concurrent queries due to the potential problems of database design, Some of the hard-

ADC conversion is the input analog signal volume, the microcontroller converted to digital volume. Reading the number must wait for the conversion to complete, the completion of a channel reading is called the sampling period. Sampling period generally = conversion time + read time. The conversion time = sampling time + 12.5 clock cycles. The sampling time is the time you tell the STM32 sampling analog through the register, the longer the setting the more accurateDetermination of sampling

Before buying a computer, we must understand the relevant configuration of the computer, memory, graphics, frequency, etc., but you know what the working frequency of computer memory? The following look at the small series to introduce you to the introduction bar. Memory frequency is the same as CPU frequency, is used

In recent days, the site optimization mixed kid in their own area QQ group saw several groups of friends in the discussion article update frequency of this problem, one of the topics caught my attention, the exact words "someone's Wuhan SEO site updated 3 daily, and my site only one weeks to update 1 articles, My blog ranking how compared to people ah ", at that time did not participate in the discussion, but the rise today, think of this topic, and t

　　memory frequency is the same as CPU frequency, is used to represent the speed of memory, it represents the maximum operating frequency that memory can achieve. The memory frequency is measured in MHz (MHz). the higher the memory frequency is to a certain extent, the faster

DDR4 How much memory frequency is appropriate? For computer enthusiasts, the greater the memory frequency, the faster the speed is relative. In today's latest DDR4 memory era, how much memory frequency is appropriate? Today's small series will share the DDR4 memory high and low frequency on the computer performance and

Baseband signal is the digital signal 1 or 0 directly using two different voltage to express, and then sent to the line to transmit. The wideband signal is a frequency division multiplexing analog signal which is modulated by the baseband signal. The basic principle of multiplexing technology is: Before entering the same wired or wireless transmission medium, each signal is modulated into a modulated signal which is not confused with each other, then

projects, and the operational risks will be reduced. This is an important reason why many transaction systems do two processes instead of one process, the risk control process and policy process are isolated from each other in the software engineering sense. Modifying the policy will not increase the possibility of disorderly reporting. The smaller the number of processes, the better. The less synchronization between different logical streams (threads), the better. With low computing workload,
