/Forex Public Platform Development (IV): Public number debugger (emulation platform, provide PHP source code)
When developing/Forex a public platform, debugging is often cumbersome and can only be changed on the top of the phone, or in the server to write logs. When your server script has a bug, the phone is not displayed, tracing is not easy. During the development process, I wrote a debugger that can si
. "With the help of the wave-wise investment lever control, the original need to the threshold of 1 million of dollars to invest in the strategy, into the low-threshold of the following products, wave-wise investment customers, only need to copy with the single, you can obtain high-end customer's equal earnings, this is the wave of intelligent investment in science and technology innovation, but also for "said the CTO of Wave Intelligence.After the wave-wise investment, fxstreet into the wave-wi
. Extended to the actual amount, 10,000, 1 million, the compounding effect will be more pronounced.
Then we often say that a little progress every day, in the end is what concept.
Suppose your ability is 1, the rate of progress of 1%, 1 years (365 days) in the end can improve how much?
One year later, your ability is 37.783.
In other words, if you devote 1% of your daily efforts to your dreams, then one year from now you have 37 steps forward to your dream.
In fact, there are not many peo
Similar to stocks, foreign currency traders also have two types:One is gambling with you. He built a warehouse between the system and the bank. Your list is traded in his warehouse at a high point, and it is connected to ECN (with little dot
trading along the direction of the trend
The main reason why people lose money is that traders try to contend with the trend and want to guess the head or bottom of the market. Traders must remember an old market motto: "The trend is your friend"
An algorithm is a set of well-defined rules that are used to solve a problem within a finite step. Popular point, that is, the process of computer problem solving. In this process, whether the formation of a problem-solving ideas or writing programs, are in the implementation of some kind of algorithm. The former is the algorithm of inference implementation, the

Algorithm Is a set of clearly defined rules used to solve a problem within a limited step. In layman's terms, it is the process of solving computer problems. In this process, no matter whether it is a problem-solving idea or writing
Program All are implementing certain algorithms. The former is an algorithm implemented by reasoning, and the latter is an algorithm
Page substitution occurs because of paged-request storage management, which is one of the ways to implement virtual storage management, where one feature is multiple--and multiple times the page is swapped in or out of memory.Best-performing page replacement algorithm: the best permutation algorithmThe more commonly used page substitution algorithms are: FIFO permutation algorithm, LRU permutation
Genetic Algorithm (GA), as a classical evolutionary algorithm, has formed a more active research field in the world since Holland was put forward. A lot of researches on GA are presented, and various improved algorithms are proposed to improve the convergence speed and accuracy of the algorithm. Genetic algorithm
The string matching algorithm is mainly two kinds, the most basic brute force solution, also is called the naïve algorithm, the other is the KMP algorithm. This article gives the simplest method of two algorithms, easy to remember and write in the interview, of course, the emphasis is still to understand the algorithm
Introduction of Ant colony algorithm, genetic algorithm and simulated annealing algorithm

First, the problem description0-1 knapsack problem, part knapsack problem. The DP algorithm of 0-1 knapsack, the greedy algorithm of partial knapsack and DP algorithm are implemented respectively.Second, the principle of the algorithm(1) 0-1-pack DP algorithm0-1 knapsack problem: There are n items and a backpack with a
We often encounter the shortest path problem, and the shortest path problem solutions are diverse, breadth-first search (BFS), Depth-first search (DFS) and Dijkstra algorithm seems to solve the problem, here is a brief introduction to these algorithms, analysis of their scope of application.
First, the principle analysis:1 Breadth First search (BFS)Breadth-First search relies on queues to solve problems. Each node in the queue needs to contain a recor
